Clean Fuels urges US to tariff renewable diesel

A US biofuel trade group called on President Donald Trump's administration today to remove a carveout that allows imported renewable diesel to avoid some tariffs, targeting a trade flow that was already dwindling this year.

The Trump administration announced a host of "reciprocal" tariffs on countries in April but exempted some energy products to avoid price spikes for consumers and businesses. While the US did not exempt foreign ethanol and biodiesel from these tariffs, renewable diesel was effectively excluded since it trades under the same tariff code as petroleum diesel.

This is an unintended "loophole" that undercuts US biorefineries, according to a letter Clean Fuels Alliance America sent to the US Trade Representative Wednesday. The group, which represents biomass-based diesel feedstock suppliers and producers, wants the Trump administration to modify the exemptions so that the tariffs apply to renewable diesel.

Sustainable aviation fuel has also benefited from this workaround — since it similarly lacks a tariff code distinct from petroleum jet fuel — and could also be impacted by any regulatory effort to distinguish renewable fuels from similar petroleum ones.

Trade policy has been a frustration for the renewable diesel industry this year, since the Trump administration did not exempt from tariffs renewable feedstocks like used cooking oil (UCO) and tallow that are frequently imported to make fuel. Trump recently threatened to end "cooking oil" trade with China too, a major UCO supplier. This dynamic allows foreign biorefineries to buy up those feedstocks for less because of lower US bidding interest and then send their fuel into the US without tariffs, refiners argue.

At the same time, the US has already taken various other steps to discourage foreign biofuels from entering the country — potentially limiting the upside for US industry even if tariff enforcement shifts.

The US has transitioned from a long-running tax break for biodiesel blenders, which credited foreign biofuels, to a new incentive this year that can only be claimed by US producers. The Trump administration has also floated revamping a biofuel blend mandate to halve program credits for fuels made abroad or from foreign feedstocks.

Biofuel imports have continued this year — notably including renewable diesel from Finnish refiner Neste's Singapore plant and Braya Renewable Fuels' Newfoundland biorefinery — but are still sharply down from last year's levels. The US has been a net importer of renewable diesel for years but is projected to export 30,000 b/d more than it imports this year and 35,000 b/d next year, according to the US Energy Information Administration.
