The DIT (Department of International Trade has launched a new commodity code checker tool for businesses and organisations importing into the UK:

https://www.gov.uk/look-up-product-commodity-code-importing

Use this service to find the commodity code for the product you’re importing into the UK.

Commodity codes are used when filling in customs paperwork and checking if there’s duty or VAT to pay. If you do not use the correct commodity code for your product you may get a penalty.

The existing commodity code system will continue from 1 January 2021.
