What it means for you
- You only register and pay once your CBAM imports reach £50,000 in 12 months. All covered goods count together, not just this code.
- The tax uses HMRC's default value unless the supplier gives you verified actual emissions for the installation that made the goods, which can be lower. The checker writes the email asking for them.
- If a carbon price was paid where the goods were made, Carbon Price Relief can reduce the tax.
- HMRC sets the rate every quarter from January 2027. Until it does, these figures use its illustrative rate, published 16 October 2026.
