UK CBAM guidance
Check your UK CBAM exposure
A simple CDS/CSV review tool is being developed. It will help you identify imports that may need UK CBAM attention.

A simple review tool, not a sign-up form
The checker is not available yet. When it launches, it will help importers review a CDS or broker CSV export for potentially in-scope goods, threshold exposure and missing emissions information.
What you can do in the meantime
- Ask your broker for a CSV of the past 12 months’ import declarations.
- Make sure it includes tax-point date, 8-digit commodity code, declared value, net mass and origin.
- Compare the codes against HMRC’s CBAM scope list.
- Use the in-scope values to begin monitoring the £50,000 threshold.
Why start with customs data?
Commodity code, value and weight are foundational to UK CBAM. A useful checker should make those declaration records easier to review; it should not replace proper customs classification, supplier verification or HMRC reporting.
