US Biodiesel And Renewable Diesel Imports Experience Significant Decline In Early 2025 Due To Tax Credit Changes

In the first half of 2025, the United States saw a notable decrease in biodiesel and renewable diesel imports compared to previous years. This decline was largely due to the removal of tax credits for imported biofuels and a general reduction in domestic consumption, as reported by the US Energy Information Administration (EIA).

One major factor contributing to the drop in imports was the elimination of tax incentives for imported biofuels. Prior to 2025, both imported and domestically produced biodiesel and renewable diesel benefited from a $1 per gallon blender’s tax credit (BTC). However, the Inflation Reduction Act introduced the Section 45Z Clean Fuel Production Credit in 2025, which applies only to domestic production. This change put imports at an economic disadvantage.

The shift in tax policy significantly affected import levels. In the first half of 2025, biodiesel imports averaged just 2,000 barrels per day (b/d), a steep decline from 35,000 b/d during the same period in 2024. Similarly, renewable diesel imports fell to 5,000 b/d from 33,000 b/d in 1H24. These figures represent the lowest import levels for any first half-year since 2012.

Another reason for reduced imports was lower domestic consumption of these fuels. The uncertainty surrounding blending requirements and negative profit margins for blending biofuels contributed to this decline. Compared to the first half of 2024, U.S. consumption of renewable diesel dropped by about 30% in early 2025, while biodiesel consumption decreased by approximately 40%.

The reduced demand for both imported and domestically produced biofuels was evident as U.S. consumption levels fell significantly. In early 2025, biodiesel consumption was less than half of what it was in early 2024, while renewable diesel usage was minimal. This decrease further impacted import levels.

The combination of changes in tax credits and lower domestic demand led to a significant reduction in U.S. imports of biodiesel and renewable diesel during this period. These factors collectively created an environment where importing these fuels became less economically viable.

This situation highlights how policy changes can directly influence market dynamics and trade patterns within the energy sector. The shift away from tax incentives for imported biofuels has had a tangible impact on import volumes and overall fuel consumption trends.
