The United States has seen a significant surge in European biodiesel imports since May 2026, with over 13 million gallons entering its ports. This influx marks a stark contrast to the period prior to December 2024, during which no such shipments were recorded. The current scenario arises despite the US being the world's largest biofuels producer, as its domestic biodiesel output in the past year reached its lowest level in over a decade, largely due to lingering policy uncertainty.
This shift comes on the heels of the Trump administration's decision in March 2026 to implement record-high biofuel blending quotas, aimed at supporting American farmers. However, the preceding months had seen numerous US biodiesel plants idled or permanently closed, leading to an immediate domestic shortage. Consequently, US refiners are now heavily reliant on foreign supplies to meet the new mandates. Imports are projected to escalate dramatically, from under 200 million gallons in 2025 to an estimated 600 million gallons in 2026 and a staggering 1.3 billion gallons in 2027.
The urgency of the situation was underscored by the arrival of 3.4 million gallons of Dutch biodiesel in the week leading up to July 9, 2026. Brett Gibbs, an analyst at Bloomberg Intelligence, emphasized the refiners' predicament, stating they have "no choice but to call upon foreign biodiesel" given the new requirements for a year-on-year jump of over 60% in alternative diesel blending.
The capacity of the domestic industry to respond to these ambitious quotas remains a key concern. Jacqui Fatka, an analyst with CoBank, highlighted the abundance of soybean oil but questioned the availability of sufficient facilities to convert it into renewable diesel, noting that "Some biodiesel plants are mothballed and completely shuttered. Do they try to come back on?" Policy uncertainty in earlier years had indeed led many plants to close or become mothballed.
The American Fuel & Petrochemical Manufacturers (AFPM), a prominent trade group, has voiced strong opposition, even suing the administration over the quotas. Geoff Moody, the group's senior vice president, asserted that the mandates "need to be reevaluated, resized, and brought back to reality." Adding to the refiners' woes, biofuel credit prices have more than doubled this year, reaching unprecedented highs. These tradable certificates, which refiners must purchase if they do not blend enough renewable fuel, are severely squeezing their profit margins.
The root of the domestic industry's struggle lies in the policy uncertainty that plagued it in prior years, characterized by shifting federal mandates and trade disputes. Many plants, operating at reduced capacity or mothballed, found themselves unable to swiftly resume full operations when the new quotas were announced in March 2026. This stark mismatch between the administration's policy ambition and the industrial sector's readiness created fertile ground for the influx of European imports.
A report released last month by academics from the University of Illinois and Oklahoma State University corroborated this, concluding that the quotas "ask the domestic biomass-based diesel industry to operate at the upper edge of its demonstrated capability while simultaneously relying on a recovery in imports that current and proposed policy work against." Despite industry challenges, Kurt Kovarik of Clean Fuels Alliance America, a biodiesel industry group, believes the mandates are "achieving exactly what Congress and the Trump administration intended." The Environmental Protection Agency (EPA), responsible for setting the rules, also maintained that the quotas, while showing "month-to-month variability," are "achievable and appropriate."
However, refiners warn that escalating credit costs could compel them to supply less fuel, creating a potential political liability for President Trump, whose "America-first" policy paradoxically now contributes to boosting imports. While the agriculture industry harbors hopes of expanding domestic output, a failure to do so might mean the ambitious quotas are not repeated in subsequent years. The ongoing dynamic between the pace of US biodiesel plant restarts and the continued rise of European imports will be critical in shaping future biofuel credit prices, refiner profitability, and the long-term viability of the Trump administration's biofuel policy.
