Question to the Department for Business, Innovation, Science and Trade:

To ask the Secretary of State for Business and Trade, with reference to his Department's press release entitled UK to set end date for imports of Russian diesel and jet fuel via third countries, published on 12 June 2026, what monitoring and enforcement measures will be used to verify that imported diesel and jet fuel are not derived from Russian crude oil after the licence expires.

HMRC is responsible for enforcing the ban on imports of oil products refined in third countries from Russian-origin crude oil and investigating suspected offences.

HMRC uses a variety of proven methods to detect sanctions breaches, including: risk and intelligence-based checks on goods imported to the UK, auditing businesses involved in the trade of goods subject to sanctions; and collecting actionable intelligence from domestic and international law enforcement partners and the intelligence community.

Importers of diesel and jet fuel may be requested to present evidence of a good's supply chain. In some cases, HMRC officials may require the production of further information relating to the goods.
