A tariff classification code is a six to ten-digit code describing a product on a customs
declaration. The code is used to determine the duties and tax which are payable at
import/export. A tariff code ensures uniformity of product classification worldwide.
The World Customs Organisation’s (WCO) Harmonised System (HS) provides 6-digit
classification codes. The Combined Nomenclature (CN) is extended to 8-digit level by the EU
for exports and to 10-digit TARIC level for imports.
There will be changes to some CN codes from 1 January 2023. Commission Implementing
Regulation (EU) 2022/1998 refers. The CN is updated annually and the TARIC daily.
Details of the main changes are available on the 2022-2023 correlation tables on the
Customs classification page of the Revenue website here:
It is the responsibility of the declarant to ensure that the goods code entered on customs
declarations is correct.
