Before you use the code

Check the facts that sit outside the code

The code can be right while what you pay still changes, because of where the goods come from, when they arrive, or extra EU measures.

  1. The product and its form Check that your product really matches this description, including what it is made of and the form it arrives in.
  2. Country of origin Trade agreements, sanctions and extra measures can change the treatment of the very same code.
  3. Current tariff measures Check today's rate, any restrictions or licences, and the quantity customs asks for, with Toldstyrelsen or TARIC.

Show the EU's own wording for these conditions
  • Compliance with the REACH restrictions defined in Column 2 of Annex XVII of Regulation (EC) No 1907/2006
