UK HMRC Issues CBAM Guidance Ahead of 2027 Launch

• HMRC published CBAM guidance ahead of the UK regime starting 1 January 2027, giving businesses practical tools to assess potential liabilities.
• The package includes product-level default emissions values for all five UK CBAM sectors, illustrative CBAM rates, and a worked example of how those rates are calculated.
• HMRC also issued a 313-page technical guide on monitoring, reporting, and verification requirements for operators, verifiers, and accreditation bodies.
• Additional guidance covers how importers can obtain and report emissions intensity data, along with verifier eligibility, accreditation, verification activities, and reporting obligations.
• Importers can now begin mapping goods to commodity codes, calculating net mass and emissions, and deciding whether to use default values or verified actual emissions data when preparing for CBAM returns and carbon price relief claims.
