CBAM CN code atlas

Six CN codes from Chapters 25 and 38: clinkers, Portland, aluminous and hydraulic cements, plus kaolinic clays.

Roughly 480 CN codes across Chapters 72 and 73: primary forms, semi-finished, flat and long products, tubes, structures, fasteners.

Chapter 76 lines: unwrought aluminium through downstream rolled, drawn, structural and selected fabricated products.

27 CN codes: ammonia, nitric acid, urea, ammonium nitrate, calcium nitrate and NPK blends.

Single CN line 2804 10 00 (hydrogen of Chapter 28).

Single CN line 2716 00 00 (electrical energy).

Frequently asked questions

What is a CN code and why does it determine CBAM scope?

The Combined Nomenclature (CN) is the EU's eight-digit goods classification used in customs declarations. CBAM scope under Annex I of Regulation (EU) 2023/956 is defined by CN code, so whether a consignment is in scope is settled by the CN code declared at import, not by the commercial description.

Where do these CN codes come from?

The atlas reproduces the codes verbatim from Annex I of Regulation (EU) 2023/956 as compiled by DG TAXUD in the CBAM Self-Assessment Tool (version 1.1, 28 March 2025). No codes are added or removed.

How many CN codes are in scope?

Across the six CBAM sectors (cement, iron and steel, aluminium, fertilisers, hydrogen and electricity), there are several hundred CN codes. Iron and steel alone covers roughly 480 lines spanning Chapters 72 and 73; hydrogen and electricity are a single CN line each.

If a CN code is not listed here, is the good out of scope?

Yes. CBAM applies only to the goods listed in Annex I by CN code. If the declared CN code does not appear in this atlas, the good is outside the current CBAM perimeter. Always validate with the CN code checker before relying on the result.

Can a single CN code cover both in-scope and out-of-scope goods?

It can. CN codes describe goods by physical and technical characteristics, not by emissions content. Annex I includes the entire CN line; whether a specific consignment under that line is treated as CBAM-relevant follows from the goods classification, not from the production route or origin.

Why are downstream products like screws and structures in scope for iron and steel?

Annex I extends iron and steel coverage to a wide range of downstream products in Chapter 73 (tubes, fittings, structures, fasteners) to limit carbon leakage through finished-goods imports. Each downstream CN line is listed individually in Annex I.

Does CBAM scope change over time?

The Commission can amend Annex I via delegated acts, and the scope is expected to widen after the definitive period begins on 1 January 2026. This atlas reflects the current Annex I as published; check the Updates page for amendments.
