H.R. 10422: Diesel Price Reduction Act of 2026

This bill would direct the Secretary of Commerce to temporarily ban exports of diesel fuel from the United States when domestic diesel prices are very high.

What triggers the export ban

The ban would begin only after the average retail price of diesel in the United States has stayed above $5 per gallon for 14 straight days.

How long the ban would last

Once triggered, the export ban would remain in place until diesel prices have been below $4.50 per gallon for 30 straight days. The ban would end the first day after that 30-day period is completed.

What “export ban” means

During the covered period, diesel fuel could not be exported from the United States to other countries. In practical terms, this would restrict domestic diesel shipments abroad in an effort to keep more diesel available inside the U.S. market.

Purpose of the bill

The bill is titled the Diesel Price Reduction Act of 2026, and its stated approach is to try to reduce domestic diesel prices by limiting exports when prices rise above a set threshold.
