CBAM CN-Code Verification Hub

Look up a CN code

Use this utility to check Stage-1 public decision pages. Detail URLs exist only for verified allowlisted codes. This lookup is not a complete CBAM CN directory.

What is a CN code?

A Combined Nomenclature (CN) code is the European Union's eight-digit coding system used to classify goods for customs and statistical purposes. It is fundamental for determining the precise category of your imported products.

Why does the CN code determine CBAM scope?

Under the CBAM regulation, only specific CN codes listed in Annex I fall within the scope of the carbon border adjustment mechanism. Identifying your correct CN code is the mandatory first step to determine whether your imported goods are subject to CBAM reporting and certificate surrender obligations.

Stage-1 verified allowlist (public pages)

Only 9 CN codes currently pass official Stage-1 membership and content-quality gates for public indexing. Chapter membership alone is not enough. Full 2026 Combined Nomenclature universe resolution remains NOT_IMPLEMENTED.
