EU CBAM Iron & Steel Emissions Calculator [CN 7201-7326 Benchmark API]
Calculate embedded carbon and EU ETS certificate liability for steel imports in under 2ms pure compute.
Quick Technical Summary: Calculate embedded carbon and EU ETS certificate liability for steel imports in under 2ms pure compute. Implementation conforms to Regulation (EU) 2023/956 & 2023/1773.
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.
| CN Code | Product Description | Sector | Default Direct Factor (tCO2e/t) |
|---|---|---|---|
| 72081000 | Flat-rolled coils, hot-rolled | iron_and_steel | 2.10 |
| 72131000 | Wire rod, hot-rolled in coils | iron_and_steel | 2.05 |
| 73181510 | Screws and bolts of iron/steel | iron_and_steel | 2.60 |
