2507 00 80: covered by UK CBAM
Imports under commodity code 2507 00 80 are covered by the UK carbon border tax (CBAM), in the cement sector. From 1 January 2027 they count towards the £50,000 threshold, and once you're over it you pay tax on the carbon in them.

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.
