EPA Finalizes RFS Set 2 Rule with Higher Biodiesel Targets, 70% SRE Reallocation
Agency delays foreign feedstock RIN penalty to 2028 while tightening program scope and boosting biofuel demand signals
The EPA has finalized its Renewable Fuel Standard (RFS) Set 2 rule for 2026 and 2027 (link), raising biomass-based biodiesel (BBD) volumes above proposed levels while adopting a 70% reallocation of previously waived obligations tied to small refinery exemptions (SREs) — a move aimed at reinforcing biofuel demand without destabilizing credit markets.
The rule also delays implementation of a controversial provision cutting Renewable Identification Number (RIN) values for imported feedstocks to 50% until 2028, while removing renewable electricity from eligibility under the program.
Higher biodiesel targets and SRE reallocation
• EPA increased BBD requirements for both 2026 and 2027 relative to its proposal, signaling stronger support for domestic biofuel production.
• The agency finalized a 70% reallocation of Renewable Volume Obligations (RVOs waived during 2023–2025 via SREs), landing near the upper end of market expectations.
• EPA said the approach balances maintaining biofuel demand with preserving a “stable and functioning credit market.”
• Notably, no reallocation applies to conventional ethanol, limiting the impact to advanced biofuels.
Based on prior EPA assumptions, BBD volumes could translate into roughly 9.07 billion RINs in 2026 and 9.20 billion RINs in 2027 when factoring in both higher targets and reallocated volumes.
In its proposed RFS volumes (link), EPA assumed an average of 1.6 RINs per gallon of biomass-based diesel (BBD) when translating the 2023–2025 standards into RIN terms. Based on that assumption, the agency proposed 7.12 billion RINs for 2026 and 7.50 billion RINs for 2027. When combined with higher volume targets and the reallocation of waived obligations, total implied requirements rise to 9.07 billion RINs in 2026 and 9.20 billion RINs in 2027.
The decision to delay implementation of the half-RIN value for imported feedstocks gives the market additional time to adjust — and, according to some observers, could open the door to further delays. The policy also aligns the RFS more closely with the 45Z Clean Fuel Production Credit, which excludes fuels produced from feedstocks sourced outside North America.
EPA’s decision to reallocate 70% of obligations previously waived under small refinery exemptions (SREs) lands toward the upper end of market expectations, though some reports had pointed to a potential 75% level. In its supplemental proposal (link), the agency sought comment on a broad range — from zero to 100% reallocation — ultimately settling on the 70% figure in the final rule.
Foreign feedstock penalty delayed
• EPA confirmed that fuels made from imported feedstocks will receive only 50% RIN value, but implementation is pushed to 2028.
• The delay gives producers time to adjust supply chains while aligning the RFS more closely with the 45Z Clean Fuel Production Credit, which restricts eligibility for non–North American feedstocks.
• Market participants note the delay could leave room for further policy adjustments before the rule takes effect.
Program narrowed to liquid and gaseous fuels
• EPA removed renewable electricity from the RFS program, citing statutory language in the Clean Air Act that emphasizes liquid and gaseous fuels.
•The move tightens the program’s scope and refocuses compliance on traditional biofuels.
Market and policy implications
• The higher BBD volumes and SRE reallocation reinforce demand signals for soybean oil and other feedstocks, supporting crush margins and biofuel investment.
• The 70% reallocation, while not a full backfill, is significant and likely to tighten RIN markets relative to recent years.
• The delayed foreign feedstock penalty tempers near-term disruption but keeps longer-term pressure on imported used cooking oil (UCO) and similar inputs.
Biofuels & RIN Market — Bullish, but Controlled Tightening
- RIN prices: Upward pressure expected, particularly D4 (biomass-based diesel) and D5 (advanced) credits.
- The 70% SRE reallocation meaningfully tightens the system versus recent years of waived obligations.
- Not a full 100% backfill → avoids a price spike, but still structurally bullish.
- Market structure:
- EPA clearly signaling a more enforceable, demand-driven RFS, reversing some of the “waiver overhang” from prior years.
- Expect less volatility tied to SRE speculation going forward.
- Key takeaway:
→ RIN market shifts from “oversupplied/uncertain” to moderately tight and policy supported.
Soybean Oil, Crush Margins & Feedstocks — Strong Upside Bias
- Soybean oil: Clear bullish demand shock
- Higher BBD volumes + SRE reallocation → incremental feedstock demand
- Reinforces already strong structural pull from renewable diesel
- Crush margins:
- Likely expand further, especially if meal demand holds
- Supports continued capacity expansion announcements
- Other fats/oils:
- Tallow, canola oil, distillers corn oil also bid higher
- Key nuance:
- Delayed foreign feedstock penalty (to 2028) keeps imported UCO and fats competitive near-term, tempering how fast soybean oil rallies.
- Key takeaway:
→ Net bullish for U.S. oilseed complex, especially soybean oil vs meal.
Renewable Diesel & Biodiesel Producers — Policy Tailwind
- Higher BBD targets:
- Directly increase required production volumes
- Supports utilization rates and margins
- Investment signal:
- Reinforces long-term capital already deployed in renewable diesel
- Reduces risk of policy-driven demand collapse
- Caveat:
- Margins still sensitive to feedstock costs (which this rule pushes higher)
- Key takeaway:
→ Bullish for producers, but margin gains partially offset by higher input costs
Petroleum Refiners — Mixed to Negative
- Compliance costs:
- Higher RVOs + reallocation → higher RIN purchasing needs
- Especially impacts non-integrated refiners
- SRE policy clarity:
- Reduces ability to rely on exemptions → structural cost increase
- Offsetting factor:
- Not a full 100% reallocation → avoids worst-case cost shock
- Key takeaway:
→ Bearish for independent refiners, neutral-to-slightly negative for integrated majors.
Ethanol Market — Neutral to Slightly Positive
- No SRE reallocation for conventional ethanol
→ avoids a major step-change in demand - Still supportive backdrop:
- General tightening of RFS improves overall blending economics
- Potential policy spillover (E15, export push)
- Key takeaway:
→ Less upside than biodiesel, but supportive macro backdrop
Trade Flows & Global Feedstocks — Delayed Disruption
- Foreign feedstock penalty delayed to 2028:
- Keeps UCO imports flowing near-term
- Avoids immediate trade dislocation or price spike
- Long-term signal:
- Strong incentive to onshore feedstock supply chains
- Aligns with 45Z tax credit structure
- Key takeaway:
→ Short-term neutral, long-term bullish for domestic feedstocks
Big Picture — Market Regime Shift
What changed vs. expectations:
- Higher BBD volumes → demand surprise to the upside
- 70% SRE reallocation → meaningful tightening
- Delayed import penalty → short-term relief valve
Net effect across markets:
- Bullish: Soybean oil, biofuel producers, RINs
- Moderately bullish: Corn/ethanol (indirect)
- Bearish: Independent refiners
- Neutral near-term / bullish long-term: Domestic feedstocks vs imports
Bottom Line
This rule tilts decisively toward demand creation without breaking the system:
→ EPA engineered a “tight but stable” RFS
→ Stronger biofuel demand signal heading into 2026–2027
→ Sets up a structurally firmer floor for ag feedstocks and RIN markets
Upshot: Overall, the final rule leans more supportive of domestic biofuel producers than the proposal, while attempting to balance compliance costs and market stability — setting up a more demand-driven RFS landscape heading into 2026–2027.
