The European Union has published new enforcement guidelines to prevent refined fuel imports made from Russian crude from bypassing its January 2026 imports ban. Under the rules, importers must provide proof that fuels were not derived from Russian crude. Contracts must include liability clauses to hold suppliers accountable if post-shipment audits reveal violations.

The rules particularly scrutinize flows via Turkey, India, and China, where blended or re-exports have been common. Refineries blending varied crude grades must demonstrate no Russian crude usage within 60 days of export eligibility. Exemptions remain for fuels from major non-Russian sources (e.g., U.S., Canada) and for “fuel in transit” used by vessels or aircraft. The move raises the compliance bar for global refiners, especially those in dual-feed systems.
