EU CBAM Extension Could Cover 200 More Steel and Aluminium Products

CBAM

EU CBAM extension plans could widen the carbon border adjustment mechanism to around 200 additional downstream products that use significant volumes of steel and aluminium. The proposal goes beyond the European Commission’s earlier plan covering 180 product codes.

EU CBAM extension reflects growing concern that carbon leakage could shift from raw materials into manufactured goods. If downstream products remain outside the mechanism, overseas producers using higher-carbon steel or aluminium could gain a cost advantage over European manufacturers.

EU CBAM extension would therefore move the system deeper into industrial supply chains. The impact could reach fabricated steel products, aluminium-intensive components and other manufactured goods that compete directly with EU-made products.

The Council presidency also wants the list of covered customs codes to remain flexible, allowing future additions or adjustments as trade patterns and circumvention risks evolve.

Downstream Expansion Targets Carbon Leakage Beyond Raw Materials

CBAM initially focused mainly on carbon-intensive upstream materials, including iron and steel, aluminium, cement, fertilizers, electricity and hydrogen.

The next phase targets a structural weakness in that model. European manufacturers can face higher carbon costs when using domestically produced steel or aluminium, while competing imported finished products may avoid equivalent charges.

Extending CBAM downstream aims to close that gap. It would place more imported products under carbon-cost rules based on the emissions embedded in their metal content and production.

For European steel and aluminium producers, the change could strengthen demand for regional low-carbon material. Downstream manufacturers may have less incentive to substitute EU metal-intensive products with cheaper imports produced under weaker carbon constraints.

But the administrative burden could rise. Importers and overseas manufacturers will need more detailed emissions data, product classifications and supply-chain documentation.

The Council presidency is therefore trying to balance wider emissions coverage with manageable reporting requirements. Three medical-use customs codes have been proposed for removal from the expanded list, reflecting concerns over unnecessary complexity in sensitive sectors.

Aluminium and Steel Supply Chains Face Wider Compliance Pressure

The expansion could have important consequences for global metals trade. Exporters of fabricated steel and aluminium products into Europe may increasingly need to demonstrate embedded emissions and product origin.

This could influence sourcing decisions far beyond primary metal. Extrusions, fabricated components, steel structures and other downstream goods may face stronger pressure to use lower-carbon feedstock.

For aluminium producers, access to renewable electricity and recycled metal could become more valuable. For steelmakers, electric arc furnace production, scrap use and lower-carbon iron inputs could improve competitiveness.

The proposal also strengthens the role of customs classification. A continuously adjustable list of CN codes would allow the EU to respond as companies change product routes or trade patterns to avoid carbon costs.

That flexibility could make CBAM more effective, but it also increases regulatory uncertainty for exporters. Companies selling into Europe will need to track not only carbon prices but also changing product coverage.

The Council has broadly supported extending CBAM to more downstream products, although some member states have argued for a narrower approach. The final scope will therefore depend on negotiations between EU institutions.

The Metalnomist Commentary

CBAM is evolving from a raw-material carbon mechanism into a wider industrial trade tool. For steel and aluminium suppliers, competitiveness will increasingly depend on proving low-carbon production across the entire downstream value chain.
