Greer Defends Trump Tariff Strategy as Senate Presses on USMCA, Prices and Farm Trade

U.S. trade chief says full North American renewal is unlikely before 2027, while lawmakers challenge Canada duties, expiring global tariffs and the costs of a policy built around multiple legal authorities.

Analysis  ·  July 22, 2026

U.S. Trade Representative Jamieson Greer defended the Trump administration’s tariff-centered trade strategy before the Senate Finance Committee, arguing that the combination of tariffs, reciprocal agreements and sector-specific enforcement is already reshaping U.S. trade toward domestic production, stronger supply chains and a smaller deficit. The hearing, however, exposed a widening dispute over the costs and legal durability of that strategy — and over whether the administration can preserve agricultural markets and business certainty while using tariffs as its principal negotiating and enforcement tool.

Committee Chairman Mike Crapo (R-Idaho) emphasized market access, enforcement and a stable U.S.-Mexico-Canada Agreement, while Ranking Member Ron Wyden (D-Ore.) accused the administration of a “tariff spree” and introduced legislation that would require congressional approval before presidential tariff actions could take effect. Greer answered that the specific statutory tools may have changed after the Supreme Court struck down the administration’s earlier global tariffs, but the strategy has not: the administration intends to keep using tariffs and trade deals to support reindustrialization, raise wages and reduce dependence on China.

Executive Summary

• USMCA renewal is unlikely in 2026. Greer said he hopes to present “potential interim arrangements” with Canada and Mexico by year-end, but stronger rules of origin and labor and environmental enforcement are likely to require negotiations into 2027.
• The next global tariff step remains unresolved. The 10% Section 122 tariff expires at the end of the week, and Greer gave no timetable for a replacement directive or for proposed Section 301 tariffs tied to forced-labor enforcement.
• The affordability dispute hardened. Democratic senators cited studies and government estimates linking tariffs to higher household costs, while Greer rejected the premise that tariffs have raised overall prices and pointed instead to lower recent inflation and selected price declines.
• There is no direct consumer-refund plan. Greer said Customs and Border Protection will refund importers of record when duties are invalidated; he did not identify a mechanism to return money directly to households that may have paid higher retail prices.
• Agriculture remained a central pressure point. Senators raised fertilizer costs, Mexican pork retaliation, sugar imports, beef access, lamb imports, soybean commitments and the risk that broad trade conflicts will overwhelm gains from smaller market-opening agreements.
• Trade policy is increasingly industrial and national-security policy. The hearing ranged from taconite, palladium, soda ash and aircraft parts to rare earths, nickel, generic drugs and the use of environmental standards as a tariff justification.

The Administration’s Case: Tariffs and Deals Are Working

Greer opened with a broad defense of the administration’s approach. He said a $1.2 trillion trade deficit, an atrophied industrial base and national-security vulnerabilities justified a continuing emergency response. Although the legal authorities have shifted, he said the administration remains committed to tariffs and negotiated deals as the core instruments for reindustrialization, higher manufacturing wages and a smaller trade deficit.

Greer cited 19 framework or reciprocal trade agreements covering 32% of global gross domestic product. He held up the Indonesia agreement as evidence that the arrangements include tariff schedules and substantive annexes, and said U.S. goods and services exports reached record monthly levels from February through May. He also argued that the composition of imports has moved away from consumer goods and autos and toward capital equipment needed for U.S. production.

The trade representative attributed a 24% year-over-year decline in the 12-month goods trade deficit through May to the reciprocal tariff program.

Of note: On agriculture, he said the monthly trade deficit had fallen below $3 billion from $6.2 billion at the end of the Biden administration and asserted that the United States is moving back toward an agricultural trade surplus. He also pointed to a lower bilateral goods deficit with China, a decline in China’s share of U.S. imports and increases in manufacturing pay and productivity. Those figures were presented as administration claims and became a recurring rebuttal when senators challenged the effects of tariffs on farms, prices and jobs.

Crapo asked how quickly the new reciprocal agreements are being implemented. Greer said Cambodia and North Macedonia had eliminated tariffs on U.S. goods, Argentina had begun tariff reductions, Malaysia and Indonesia were moving toward implementation in the fall, Jordan had already liberalized parts of its market, Israel had acted to accept U.S. standards and the European Union had lowered industrial tariffs while opening agricultural tariff-rate quotas.

When Crapo asked how USTR would ensure that those commitments endure, Greer said enforcement ultimately means the willingness to impose tariffs. He pledged to use Section 301 and other tools when partners fail to implement agreements, framing tariffs not only as negotiating leverage but as the final sanction behind trade rules.

Perspective: Greer’s testimony showed that the administration no longer treats tariffs as a temporary bridge to traditional free-trade agreements. Tariffs are the organizing principle of the policy: they are used to force negotiations, police implementation, protect selected industries and redirect investment. That approach can produce rapid concessions, but it also makes business certainty dependent on continuing presidential decisions and on the legal survival of multiple tariff authorities.

USMCA: No Full Renewal Before 2027

The clearest policy news from the hearing was Greer’s timetable for the U.S.-Mexico-Canada Agreement. Crapo asked for a realistic conclusion date, noting the bipartisan importance of business certainty. Greer said he was leaving after the hearing for Mexico City to meet President Claudia Sheinbaum and Economy Secretary Marcelo Ebrard while U.S. and Mexican teams continued negotiations.

Greer said the administration hopes to develop options before year-end for “potential interim arrangements” —one with Canada and one with Mexico. But he acknowledged that some of the most consequential issues will take longer. Those include tighter rules of origin intended to increase North American production, as well as stronger labor and environmental enforcement in Mexico. His answer effectively confirmed that a full renewal or comprehensive revision is unlikely before 2027.

Sen. John Cornyn (R-Texas) asked what Congress should infer from the administration’s July 1 decision not to renew USMCA at the joint review. Greer said the administration chose not to “rubber stamp” the agreement and instead entered the annual review process to improve it. He described agricultural and services access as load-bearing pillars that generally work, while identifying the U.S. trade deficit with Mexico, auto investment and rules of origin as areas requiring change. The administration wants benefits to remain within North America rather than flow through Mexico to producers in China, Vietnam or other third countries.

Cornyn also pressed Mexico’s compliance with the 1944 Water Treaty, which is crucial to South Texas agriculture. Greer said the issue is primarily under State Department jurisdiction but warned that President Trump would have difficulty agreeing to renewal or revisions if Mexico did not cooperate across a broader set of disputes, including water and border security. That answer indicated that USMCA leverage may be applied to issues formally outside the trade agreement.

Greer gives a commitment: Sen. Catherine Cortez Masto (D-Nev.) secured Greer’s explicit support for legislation she has introduced with Sen. Jerry Moran (R-Kan.) to create a travel and tourism working group within USMCA. The commitment was one of the few unqualified bipartisan agreements during the hearing.

Perspective: The administration is preserving the existing agreement while withholding renewal to maximize leverage. Interim bilateral arrangements could prevent a complete breakdown, but they also risk fragmenting a trilateral framework into separate U.S./Mexico and U.S./Canada bargains. Businesses may retain duty-free access under the current pact, yet still delay investment if core rules — especially auto content requirements — remain unsettled into 2027.

Canada: 50% Tariffs and Business Uncertainty

Canada was the most politically charged bilateral issue. The administration announced 50% tariffs under Section 338 of the Tariff Act of 1930 on nearly $20 billion in Canadian motor vehicles, alcoholic beverages and dairy products. The actions are scheduled to take effect 30 days after the July 20 announcement. USTR says the measures respond to Canadian restrictions on U.S. autos, liquor and dairy access; critics say they raise costs and destabilize the United States’ closest trading relationship.

Wyden asked whether some Canadian goods would face higher U.S. tariffs than comparable Chinese products. Greer said China remains subject to much higher tariffs overall, citing tariffs on electric vehicles, steel and aluminum, but acknowledged that a small number of Canadian products could face a higher rate and promised a product-level analysis for the record. Wyden argued that imposing harsher treatment on Canada in any category while easing some restrictions with China reflected a misplaced set of priorities.

Sen. Michael Bennet (D-Colo.) focused on agriculture, noting that Canada and Mexico buy nearly $60 billion in U.S. agricultural products annually. He asked Greer to guarantee that farmers would not lose market access and challenged the administration’s willingness to risk retaliation. After a tense exchange in which Greer initially blamed the agricultural deficit on the Biden administration, Greer gave a direct commitment: the United States would maintain market access in both countries. He said his Canadian counterpart had not indicated an intention to retaliate against the new actions.

Sen. Peter Welch (D-Vt.) described the practical effect of trade conflict on a border state. He said Vermont tourism from Canada was down sharply and cited layoffs or higher costs at Rovers North, Orvis, Jasper Hill Farm and Hill Farmstead Brewery. Welch asked for greater clarity, more stability and more respectful treatment of Canada. Greer responded that most Canadian trade continues to receive preferential treatment and argued that the new tariffs target Canadian barriers to U.S. liquor, autos and cheese. He offered to meet directly with the Vermont companies Welch named.

Sen. Marsha Blackburn (R-Tenn.) submitted questions for the record on Canada’s removal of U.S. distilled spirits from provincial shelves, including Jack Daniel’s. She asked what additional pressure would be used to restore access. Her broader message was that Tennessee companies support reshoring and reciprocal trade but are increasingly reluctant to make major capital investments amid rapidly changing tariff rules.

Perspective: The Canada dispute illustrates the administration’s willingness to use concentrated, very high tariffs inside an otherwise preferential trading relationship. The direct coverage is far narrower than “most Canadian goods,” but the economic effect can spread through integrated auto, dairy, retail and tourism networks. The absence of an announced Canadian retaliation does not eliminate the risk; it merely leaves the response uncertain while the tariffs approach their effective date.

Section 122 Expiration and the Next Tariff Authority 

The administration’s 10% global tariff under Section 122 expires at the end of the week after reaching the statute’s 150-day limit. The levy was imposed after the Supreme Court struck down the administration’s earlier global tariff program, and it has served as a temporary foundation while USTR developed alternative legal routes.

Greer provided little guidance on what will happen next. After the hearing, he told reporters that he first had to consult the president and receive a signed directive. He did not commit to replacing the duties before they expire, nor did he give a timetable for final action in USTR’s Section 301 investigations into foreign failures to address forced-labor goods. Those investigations are widely viewed as a possible vehicle for a new country-by-country tariff structure.

The uncertainty matters operationally as well as politically. Importers, customs brokers and retailers must know which rates apply at entry, while trading partners need to know whether the United States will allow a gap, reimpose a temporary levy or move immediately to a new legal basis. Greer also left open the possibility that Section 122 could be used again, although the statute does not explicitly resolve whether repeated temporary actions are permissible.

Perspective: The administration appears committed to preserving a broad tariff floor even as it migrates from one statute to another. That legal improvisation keeps pressure on trading partners but also deepens the very uncertainty that Republican and Democratic senators said is delaying investment. The next directive will be an important test of whether the White House prioritizes uninterrupted tariff coverage or a more defensible, targeted legal structure. 

Congressional Tariff Power and the Democratic Challenge 

Wyden used the hearing to introduce the Congressional Trade Powers Reform Act, which would require congressional approval before tariff actions under a range of trade statutes could take effect. The bill would also create an advisory mechanism intended to help Congress exercise real-time oversight. Wyden said Congress would not impose a 50% tax on products that raise costs for Americans and argued that the Constitution gives lawmakers, not the president alone, the central role in trade policy.

Greer did not directly engage the constitutional argument. Instead, he defended the results of executive action and described tariff authority as essential to enforcement. Crapo, meanwhile, emphasized the need for close consultation and collaboration between Congress and the administration but did not endorse Wyden’s proposal. Blackburn’s questions demonstrated that concern over unpredictability is not limited to Democrats, even though Republican senators generally focused on obtaining sector-specific relief rather than restricting presidential authority.

Perspective: The fight over trade powers is moving from an abstract institutional debate to a practical question for businesses and consumers. Court rulings have forced the administration to change statutes; Congress is now considering whether to impose approval requirements before the next tariff can take effect. The durability of the Trump trade agenda may therefore depend as much on institutional control as on negotiations with foreign governments. 

Consumer Costs, Inflation and Tariff Refunds 

The most contentious exchanges involved whether tariffs have raised prices and who should receive refunds after duties are invalidated. Sen. Elizabeth Warren (D-Mass.) cited Congressional Budget Office and Treasury-related estimates that tariffs cost the average family about $1,700. She asked Greer directly whether tariffs had increased prices. Greer answered no, pointing to core inflation of 2.6% and recent declines in selected prices.

Warren then asked whether consumers would receive any of the money being returned after the Supreme Court decision. Greer said customs law requires refunds to go to the foreign or domestic importers of record that paid the duties. Warren pressed for a mechanism to reimburse households that may have borne the cost through higher retail prices. Greer did not identify one and repeatedly returned to the established importer-refund process.

Sen. Sheldon Whitehouse (D-R.I.) raised two related concerns: small businesses may lack the staff and expertise to navigate the refund process, and large companies that receive refunds are not required to pass the money through to customers. Greer said Customs and Border Protection has a relatively straightforward online portal and offered to help constituents who encounter problems. He rejected Whitehouse’s premise that tariffs were fully passed through to consumers, arguing that some costs were absorbed by foreign companies or diluted in supply chains.

Sen. Raphael Warnock (D-Ga.) asked whether USTR had produced a rigorous, peer-evaluated study refuting research that links tariffs to inflation. Greer cited Council of Economic Advisers work and Bureau of Labor Statistics data showing declines in eggs, smartphones and butter, but he did not commit to Warnock’s request for a formal USTR study within 60 days. The exchange became increasingly combative as Warnock argued that item-level price declines do not answer the causal question of whether tariffs added to inflation.

Warnock also challenged the administration’s manufacturing claims, citing a net loss of manufacturing jobs since Trump returned to office. Greer said monthly manufacturing employment had turned positive in 2026 after losses in the prior administration and predicted a net gain by 2030 if current policies continue. Warnock countered with examples of Georgia firms facing layoffs because specialized steel inputs are subject to a 50% tariff.

Perspective: The hearing did not resolve tariff incidence. Aggregate inflation can fall while tariffs still raise the price of specific imported goods or inputs, and selected price declines do not prove the absence of tariff effects. The more concrete policy conclusion is that the government has no direct consumer-refund architecture. Legal refunds flow to importers, leaving any benefit to consumers dependent on company decisions and competitive market pressure. 

China: Dependency, Critical Minerals, Agriculture and Enforcement

China appeared in almost every major policy debate. Wyden accused the administration of being tougher on Canada than on China, pointing to the creation of a U.S./China trade and investment mechanism while Canada faces new 50% duties. Greer responded that China remains subject to far higher tariffs overall and said some Chinese products face duties above 50% or even in triple digits.

Sen. Chuck Grassley (R-Iowa) asked how the United States could force China to remove export restrictions on fertilizer. Greer said China is not a free-market economy and uses supply chains to advance political and food-security goals. He promised to raise the issue but warned that China may continue to control fertilizer exports for its own purposes and to “weaponize” access when convenient.

Cornyn asked about rare earths and processed critical minerals, areas in which China controls much of global capacity. Greer said China has committed to expedite export-control applications for U.S. companies, including shipments routed through third countries. He said the United States is receiving the majority of what it needs, though not at the desired pace or volume, and retains trade tools that can be reactivated if China fails to comply. He stressed that domestic production remains the long-term answer.

Sen. John Barrasso (R-Wyo.) asked about foreign barriers to U.S. beef. Greer said China had agreed to re-register eligible U.S. beef facilities and that USTR was pressing for implementation because Chinese buyers value cuts that have less demand in the United States. Blackburn also submitted written questions on how the administration will enforce Chinese soybean purchase commitments and stop dumping and transshipment that injure U.S. producers.

Perspective: The administration is pursuing a dual China policy: tactical agreements to keep critical minerals and agricultural trade moving, paired with a long-term effort to reduce dependence and preserve tariff leverage. That is not a return to normal trade. It is managed interdependence, with compliance judged through recurring calls, licensing decisions and the threat that suspended or existing trade tools can be reactivated.

Agriculture: Fertilizer, pork, sugar, beef and lamb 

Agriculture received unusually detailed attention because senators from both parties described producers as financially vulnerable. Crapo stressed that USMCA accounts for nearly one-third of U.S. agricultural exports and asked how new agreements would produce real market access. Greer pointed to tariff reductions and agricultural quotas in Asia, the Middle East and Europe, while repeating that the United States is moving back toward an agricultural trade surplus.

Grassley focused first on fertilizer. He praised the delay of duties on Moroccan phosphate and asked USTR to expand supply, particularly by removing tariffs on anhydrous ammonia. Greer said the administration is trying to balance domestic production and food security with fair import competition. He agreed that farmers need competitively priced inputs, but he stopped short of promising a specific tariff removal.

Grassley then asked about Mexico’s investigation of U.S. pork following the breakdown of tomato negotiations. Greer said Mexico had not retaliated, but USTR was monitoring the case closely and had raised it repeatedly at senior levels. He warned that Mexican action against pork would carry consequences because Mexico depends heavily on the U.S. market. The answer was designed to reassure Iowa producers, but it also underscored how quickly disputes in one commodity can spill into another.

Bennet challenged Greer to protect the Canadian and Mexican markets at a time when corn, soybeans, wheat and other crops are below breakeven. Greer ultimately promised to maintain and expand access, but the heated exchange showed the administration’s sensitivity to claims that farmers may need another round of direct payments to offset trade disruptions. Bennet argued that producers want dependable markets rather than compensation for policy-created losses.

Sen. Tina Smith (D-Minn.) asked USTR to investigate subsidized foreign sugar that can enter the United States and still sell below domestic production costs. Greer said USTR is working with the industry to establish the evidentiary basis for a Section 301 case and wants action, but is still gathering information. Smith stressed that timing is critical for sugar-beet cooperatives deciding whether to plant acreage that may lose money.

Barrasso highlighted beef access and the new safeguard investigation into lamb imports. Greer said Australia had reopened to U.S. beef after two decades, China was moving on facility registrations and other countries had reduced barriers. On lamb, he explained that the International Trade Commission will collect data on import surges and serious injury before recommending whether the president should impose relief.

Perspective: The administration’s agricultural strategy is highly transactional: protect fertilizer supply, deter retaliation, open individual markets and initiate trade-remedy cases for politically sensitive commodities. Those steps can be meaningful, but they do not eliminate the macro risk that broad tariffs raise input costs or provoke retaliation in much larger markets. The central farm-policy test will be whether USMCA access and China purchases remain stable while new disputes multiply. 

Industrial Policy and Critical Supply Chains 

The hearing demonstrated how far U.S. trade policy has moved beyond tariffs on finished consumer goods. Senators asked for protection or market access across basic materials, strategic minerals, aircraft, pharmaceuticals and chemicals, often linking trade remedies directly to national security and regional employment.

Smith asked for help restoring Minnesota taconite production after layoffs at Hibbing Taconite and Minorca Mine. Greer said trade tools could be phased in over a short period to signal that domestic iron-ore pellets will be favored and to reduce import dependence. His response suggested openness to a targeted measure, although he did not specify the statute or tariff level.

Sen. Steve Daines (R-Mont.) argued that Russian palladium is being dumped below market prices, contributing to the loss of 700 Montana mining jobs. Greer said he supports corrective action wherever markets are distorted, especially for a critical mineral such as palladium. Barrasso similarly asked USTR to defend Wyoming soda ash against a possible Indian import restriction; Greer promised to raise the matter with his Indian counterpart and press for a fair trade-remedy process.

Cortez Masto questioned whether the Commerce Department would release the results of its Section 232 investigation into aircraft and aircraft parts, which the industry says is chilling investment. Greer said the president had directed the administration to seek negotiated landing zones because the supply chain is especially sensitive. He acknowledged that the reports inform USTR negotiations and agreed to raise disclosure with the commerce secretary.

On Indonesia, Cortez Masto asked whether commitments to ease critical-mineral export restrictions were real, given public denials by Indonesian officials. Greer said Indonesia has agreed to expedite export approvals and that USTR had successfully intervened when a shipment was blocked. He said the United States must continue to hold Indonesia to the agreement while recognizing Jakarta’s effort to avoid dependence on a single regional buyer, particularly China.

Cornyn asked about active ingredients for generic pharmaceuticals. Greer said there are no current Chinese export controls on those inputs, but agreed that dependence is a strategic vulnerability and referenced a presidential initiative to accelerate domestic generic-drug production. Barrasso also asked about chemical exports, prompting Greer to describe a two-track approach: eliminate tariffs and address regulatory, certification and other non-tariff barriers market by market.

Blackburn flagged a specialty wood-pulp product that was included in the final Brazil tariff list even though U.S. supply cannot meet domestic demand. She requested a meeting with an affected Tennessee employer. The question captured a recurrent implementation problem: a tariff designed to punish foreign practices can also raise costs for U.S. manufacturers that lack an immediate domestic substitute.

Perspective: The administration’s industrial strategy is increasingly granular. It is willing to use different authorities for taconite, palladium, aircraft, pharmaceuticals, chemicals and critical minerals, often with sector-specific phase-ins or negotiated exemptions. That flexibility can target genuine vulnerabilities, but the accumulation of cases makes the tariff system harder for companies to model and increases pressure for politically connected exclusions. 

Environmental and Labor Enforcement 

Whitehouse identified one of the few clear areas of bipartisan agreement: foreign producers should not gain a trade advantage by operating under weaker pollution standards. Greer reaffirmed that such differences can justify tariff adjustments and said new reciprocal agreements require trading partners to raise environmental standards to at least a minimum level.

Greer pointed to the Brazil Section 301 action, which includes illegal deforestation among the practices USTR found unreasonable and burdensome to U.S. commerce. He argued that lower environmental standards can create an unfair cost advantage over U.S. farmers. Whitehouse encouraged USTR to strengthen enforcement, noting that both Republican and Democratic administrations have historically failed to use environmental provisions aggressively.

Labor and environmental provisions also complicate the USMCA schedule. Greer told Crapo that stronger enforcement against Mexico will take time and may require additional consultation with Congress in 2027. That means the administration is simultaneously using environmental issues to justify immediate unilateral actions in some countries and treating negotiated labor and environmental rules as a longer-term project in North America.

Perspective: Environmental enforcement may provide USTR with a broader and more politically durable basis for targeted tariffs, especially when domestic producers face measurable cost disadvantages. The policy challenge will be maintaining credible evidence and consistent standards. If environmental claims are applied selectively, they may be viewed as protectionism; if applied transparently, they could attract unusual bipartisan support.

Services, Tourism and Cross-Border Sentiment

Cortez Masto noted that travel and tourism —historically the largest U.S. services export — moved from surplus to a reported $14 billion deficit in 2025. She asked whether USTR had analyzed the decline, particularly in Las Vegas. Greer said overall U.S. services exports remain at record levels but acknowledged that tourism is a distinct problem. He offered to work with the Commerce Department on promotion and supported a USMCA tourism working group.

Welch gave the issue a different dimension. He said Canadian visitors were canceling Vermont trips in response not only to tariffs but also to President Trump’s rhetoric toward Canada. That loss of goodwill, he argued, is reducing tourism and sales even where no tariff applies directly. Greer said he could not resolve every factor but would work with Vermont businesses and defend continued North American trade.

Perspective: The tourism discussion exposed a blind spot in a trade strategy centered on goods deficits and factory investment. Services trade can be harmed by border friction, political rhetoric and consumer sentiment without a formal tariff. A durable North American strategy therefore requires more than rules of origin; it also requires predictable travel, business confidence and public trust across the border.

Central Asia, Jackon-Vanik and Market Diversification 

Daines urged repeal of Jackson-Vanik trade restrictions for Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan and Azerbaijan, arguing that the Cold War-era provisions impede deeper ties with strategically important countries surrounded by Russia, China, Afghanistan and Iran. He noted that his repeal effort is bipartisan and said the remaining restricted countries should not be grouped with North Korea, Cuba and Belarus.

Greer said the administration would likely support congressional action if repeal is paired with meaningful market opening. He described Uzbekistan as a country of roughly 40 million people that has offered substantial tariff reductions and is actively orienting its economy toward the West. He also highlighted Kazakhstan’s critical-mineral potential, while cautioning that the United States should diversify supply rather than replace one dependency with another.

Perspective: Central Asia fits the administration’s wider strategy of combining market access with supply-chain diversification. Repealing legacy restrictions could strengthen geopolitical ties and open new markets, but the economic scale will remain modest compared with Canada, Mexico, China and the European Union. Its strategic value is primarily optionality: more sources of minerals and more partners outside Chinese and Russian influence.

Hearing Dynamics and Political Meaning 

Greer was prepared, data-driven and often combative. When Democratic senators sought yes-or-no answers about price increases, consumer refunds or job losses, he frequently rejected the premise and pivoted to broader measures of inflation, trade deficits, exports and manufacturing wages. That approach reinforced the administration’s narrative but sometimes left the specific question unanswered.

Democrats concentrated on affordability, legal authority, consumer refunds, farm stress and the gap between public announcements and enforceable agreements. Republicans generally praised the administration’s goals and used their time to seek relief for state industries, but several also raised uncertainty, market access and implementation problems. Crapo’s emphasis on certainty, Grassley’s fertilizer concerns, Cornyn’s USMCA questions and Blackburn’s warning about investment hesitation showed that congressional support for tougher trade policy is not the same as support for unlimited volatility.

The most durable bipartisan positions were support for USMCA’s core market access, stronger enforcement against unfair trade practices, reduced dependence on China and protection of strategic supply chains. The deepest divisions involved how broad tariffs should be, whether consumers bear the cost, how much authority the president should possess and whether the administration’s rapid sequence of deals provides enough legal and commercial certainty.

Perspective: The hearing was less a review of a settled trade agenda than a preview of the next phase. The administration is rebuilding its tariff structure after a Supreme Court defeat, delaying USMCA renewal to seek additional concessions and expanding trade policy into environmental, labor, industrial and national-security domains. Congress is deciding whether to accommodate that model, constrain it or demand more transparent evidence of its economic results. 

Lawmaker-By-Lawmaker Question Guide 

Crapo: Asked about the USMCA timeline, implementation of reciprocal agreements and long-term enforcement. Greer said interim Canada and Mexico arrangements may be ready by year-end, while rules of origin and labor and environmental issues likely extend into 2027; he also promised aggressive tariff enforcement.

Wyden: Challenged the administration for treating some Canadian products more harshly than Chinese goods, criticized pharmaceutical arrangements and introduced a bill requiring congressional approval of tariffs. Greer defended the overall tariff differential with China and said foreign trade agreements are public, while domestic drug-pricing deals fall to other agencies.

Grassley: Pressed for lower fertilizer costs, action against Chinese export restrictions and protection of U.S. pork from Mexican retaliation. Greer promised continued attention, warned that China uses supply chains strategically and said Mexico had been told that action against pork would carry consequences.

Bennet: Demanded a guarantee that USMCA negotiations would not cost farmers access to Canada and Mexico. After a sharp exchange, Greer committed to maintaining and expanding agricultural access and said Canada had not signaled retaliation.

Whitehouse: Asked USTR to penalize pollution-based trade advantages and improve tariff refunds for small businesses. Greer endorsed environmental tariff adjustments, cited the Brazil deforestation case and offered constituent assistance with the CBP refund portal.

Cornyn: Asked why the administration declined to renew USMCA, whether Mexico’s water obligations could be tied to the review and how China is handling critical-mineral exports. Greer said the goal is a stronger agreement, warned Mexico must cooperate broadly and said Chinese mineral flows are continuing but remain insufficient.

Daines: Sought support for Jackson-Vanik repeal, deeper trade with Central Asia and action against Russian palladium dumping. Greer was receptive to repeal tied to market opening, highlighted Uzbekistan and Kazakhstan and supported corrective action for distorted palladium markets.

Warren: Asked whether tariffs raised household prices and whether consumers would receive refunds. Greer denied an overall price increase from tariffs and said refunds legally go to importers of record, not directly to households.

Smith: Requested trade protection for Minnesota taconite and a Section 301 investigation into subsidized foreign sugar. Greer said both areas merit action and that USTR is gathering the evidence needed for a sugar case.

Cortez Masto: Pressed for release of the aircraft Section 232 reports, action on tourism and clarity on Indonesia’s mineral commitments. Greer agreed to raise disclosure with Commerce, endorsed a USMCA tourism working group and said Indonesia is expediting exports under U.S. pressure.

Welch: Described Vermont layoffs, tourism losses, higher equipment costs and Canadian customer cancellations. Greer defended targeted action against Canadian barriers but offered direct meetings and assistance to affected companies.

Barrasso: Raised Indian restrictions on soda ash, beef access, chemical barriers and lamb imports. Greer promised advocacy in India, continued pressure on China and other markets for beef, non-tariff-barrier negotiations for chemicals and a full ITC safeguard review for lamb.

Warnock: Asked for rigorous analysis of tariff inflation and manufacturing job effects. Greer cited BLS and administration data, offered additional information and predicted manufacturing employment would turn decisively positive, but did not commit to a new USTR study within 60 days.

Blackburn: Submitted written questions on Canadian liquor restrictions, Mexican tax audits, auto-industry consultation, Brazilian wood pulp and Chinese soybean enforcement. Her questions emphasized that companies want reciprocal trade but need predictable rules before investing.

What to Watch Next 

• Section 122 deadline: Whether the president signs a replacement directive before or after the 10% global tariff expires at the end of the week.
• Forced-labor Section 301 decision: The final country list, tariff rates, implementation date and legal theory for USTR’s proposed replacement structure.
• Mexico City negotiations: Whether Greer’s meetings produce a concrete interim framework and how far the United States pushes auto rules of origin, water compliance and broader security conditions.
• Canada response: Whether Ottawa retaliates, negotiates exemptions or waits for the 50% Section 338 tariffs to approach their effective date.
• Agricultural enforcement: Mexican pork, Chinese soybean, beef and other commodity purchase commitments, fertilizer supply, sugar Section 301 work and the lamb safeguard investigation.
• Industrial cases: Potential action on taconite, palladium, soda ash, aircraft, specialty wood pulp and critical-mineral export restrictions.
• Congressional reaction: Whether Wyden’s trade-powers bill attracts bipartisan support as courts and businesses demand a more predictable tariff framework.
