Specification & Structural Breakdown

Iron and steel imports into the European Union account for the largest volume of CBAM declarations. Covering pig iron (CN 7201), crude steel (CN 7206), semi-finished billets (CN 7207), hot-rolled coils (CN 7208), cold-rolled sheets (CN 7209), wire rod (CN 7213), seamless pipes (CN 7304), and fasteners (CN 7318).

Many steel products are categorized as complex goods under Annex II. For example, steel screws (CN 7318 15 10) require factoring in the embedded carbon from upstream wire rod (CN 7213 10 00) or crude steel billets. The API automatically resolves precursor emissions.
