# RIN Haircut Debate: How a 50% RIN Credit for Imports Could Reshape Biomass-Based Diesel Markets - RINSTAR

> RINSTAR explains the proposed half-RIN rule, which would cut RIN value to 50% for domestic biofuel made from foreign feedstock and for imported biofuel. It also notes EPA proposed lowering the D4 RIN equivalence for non-ester renewable diesel from 1.7 to 1.6.

## Why it matters

Halving RIN value for imported feedstock raises compliance costs for importers and favors domestic soybean oil and FAME biodiesel, supporting domestic oil prices.
