On 9 April 2026, HMRC published draft regulations on the Carbon Border Adjustment Mechanism (CBAM). This is HMRC’s second UK CBAM consultation of 2026. The first sought views on draft legislation setting out the administrative requirements of this new indirect tax, along with provisions outlining the CBAM rate and carbon price relief (which is available where imported goods have borne certain types of carbon taxation in their countries of origin).
The new tranche of draft legislation sets out provisions that will govern the calculation of embedded emissions, record-keeping and procedures for monitoring and verifying emissions data. It will therefore be of interest to importers of in-scope goods (from the aluminium, iron and steel, fertiliser, cement and hydrogen sectors) as well as overseas manufacturers of those goods. Anyone in the supply chain importing tonnes of metal widgets, for example, should start taking note now!
