Aerospace Industry: Iron and Steel

Question: To ask the Secretary of State for Business and Trade, what assessment he has made of the potential impact of the proposed 50% steel tariff on the UK's aerospace supply chain, including an evaluation of the length of time it would take to recertify specialised steel components from UK suppliers.

Answer: The Government has carefully designed this measure to minimise downstream impacts while addressing the existential threat to UK steelmaking. Current production levels have been considered in determining quota sizes. The measure has been designed, as far as is technically possible, to only cover steel requirements that can be met in the UK. Where this is not feasible, quotas have been designed to allow sufficient imports. We will closely monitor the impacts and will review the measure after 12 months to ensure the balance is right for businesses in all sectors, including aerospace.
