UK CBAM 2834 21 00 Nitrates of potassium — in UK CBAM

Imports under this code are CBAM goods in the UK from 1 January 2027. The importer accounts for their embodied emissions and pays the CBAM charge.

2834 21 00 – Nitrates of potassium

Greenhouse gas: Carbon dioxide and nitrous oxide.

What the importer accounts for

• Embodied emissions per tonne of goods: direct emissions only, until 2029 at the earliest.
• Actual emissions data from the producer, or default values.
• Any carbon price already paid abroad, which can reduce the charge.

The £50,000 threshold

You must register if the value of CBAM goods you imported over the last 12 months, or expect to import in the next 30 days, exceeds £50,000. Below it, keep records that show you are not liable. UK CBAM overview.
