The CBAM definitive period requires embedded emissions to be declared per product, and stainless steel mainly falls under several codes in CN Chapter 72.

Preparation needed: 1) A product-to-CN-code mapping table (coils, plates, tubes, and sections classified separately). 2) Production route: electric furnace/basic oxygen furnace, scrap ratio, alloy additions. 3) Direct emissions: energy consumption and emission factors for each process step—smelting, rolling, and heat treatment. 4) Indirect emissions: emission factor and quantity of purchased electricity. 5) Verification: a report issued by an accredited verification body, with original supporting documents retained for at least 4 years.

It is recommended to start with a pilot on a single product line, get the data chain working end to end, and then roll it out across all product categories.
