Registration threshold calculator
Law as at 13 September 2026. The calculator runs in your browser and sends nothing anywhere.
Paragraph 2(2) of Schedule 17 makes a person trigger registration in two ways: on the first day of a month, if the covered goods imported in the preceding twelve months had an aggregate customs value of £50,000 or more; or on any day, if the person expects to import £50,000 or more of covered goods within thirty days. Goods of UK origin, returned goods and re-exported special procedure goods are left out, and goods imported before 1 January 2027 do not count. Enter customs values in pounds, leaving out those goods.
The calculator applies the words of the Act to the figures you enter. Whether a good is covered, what its customs value is and whether an exemption applies are questions the calculator cannot answer; chapters 1, 9 and 17 of UK CBAM for Importers explain how to settle each.
