Aluminium processors supplying covered products to the European Union must be able to identify the metal entering their production processes and establish the emissions information relevant to their CBAM calculations. The requirements make supplier documentation and the traceability of intermediate materials important elements of purchasing and production management.
The European Commission’s aluminium guidance distinguishes raw materials from relevant precursors when determining embedded emissions. It classifies primary unwrought aluminium as a simple good and explains that alumina, carbon anodes and scrap are not treated as precursors carrying upstream embedded emissions into that calculation. Downstream aluminium products, however, can incorporate emissions associated with relevant precursors.
Distinguishing Aluminium Inputs and Precursors
The treatment of CBAM aluminium precursors is important when processors assess the emissions associated with materials used in manufacturing. The applicable calculation depends on the classification of the input and the requirements for the resulting covered product.
This distinction also affects how buyers evaluate unwrought aluminium emissions. A general carbon footprint covering all raw materials and production inputs does not automatically correspond to the emissions figure required under CBAM.
Traceability Across Aluminium Processing
For companies purchasing billets, slabs and other intermediate products, billet and slab CBAM assessments require records that support the applicable calculation and preserve the identity of the relevant production materials.
The challenge becomes more complex when processors source metal from multiple suppliers. Documentation must remain linked to the relevant production identity as materials move through warehousing, conversion and subsequent manufacturing operations.
Effective aluminum supplier traceability can help maintain this connection between incoming metal and the emissions information used for the finished product. EU customers may consequently request more specific production and emissions records than those contained in a general sustainability statement.
Supplier Records and Compliance Requirements
For aluminium processor compliance, the central task is to establish the emissions associated with the covered product being sold and retain documentation that supports the applicable calculation.
The quality and consistency of supplier records can influence how readily processors explain their emissions figures to European customers. Maintaining traceable production information helps make those figures easier to verify and incorporate into purchasing assessments.
