The European Parliament voted on Tuesday to expand the EU’s Carbon Border Adjustment Mechanism (CBAM) to roughly 457 downstream manufactured products, more than double the 180 products the European Commission proposed in December 2025. The negotiating position, adopted by 464 votes to 50, now goes into talks with member states, whose own stance covers only about 200 additional products. For importers, exporters and anyone pricing carbon into supply chains, the message is that CBAM is moving from a tax on basic materials to a tax on the goods made from them.

What Parliament Actually Voted For

CBAM has been fully operational since 1 January 2026 and currently covers imports in six sectors: iron and steel, aluminium, cement, fertilisers, electricity and hydrogen. Importers buy CBAM certificates to match the carbon cost that EU producers pay under the EU ETS.

The Commission’s December 2025 proposal sought to add 180 downstream products with high carbon leakage risk and a high share of steel or aluminium content, on average 79 percent according to a European Parliamentary Research Service briefing. The list targeted goods such as machinery, hardware and fabrications, vehicle components, domestic appliances and construction equipment.

Parliament’s position goes well beyond that. Lawmakers agreed to expand the list by over 450 products, reaching into categories the Commission had not prioritised, including solar panels, heat pumps and appliances. Finished steel and aluminium products such as fasteners, wire, springs and household articles would also be pulled in, taking CBAM deeper into manufacturing supply chains rather than stopping at the raw material stage.

The Leakage Logic Behind the Expansion

The driver is a structural gap in the current design. If imported steel faces a carbon charge but a finished component made from the same steel enters the EU outside CBAM, production can shift one step down the supply chain, outside the bloc, without reducing any emissions. The Council’s own position states explicitly that the present system risks encouraging non-EU manufacturers to convert steel and aluminium into downstream products before exporting them to Europe, displacing EU-manufactured goods whose producers pay ETS costs.

That framing matters for how the file will be sold politically. This is no longer only a climate instrument; it is increasingly an industrial competitiveness measure, and the 464-50 vote margin shows how little organised opposition the expansion now faces inside Parliament.

Anti-Circumvention Rules Get Teeth

MEPs paired the wider scope with a tighter enforcement package:

  • A lower “slightly modified” threshold, so that small changes to a good can more easily qualify as circumvention, while clarifying that the rules should catch only modifications made specifically to dodge CBAM, not normal business decisions.
  • Pre-consumer steel and aluminium scrap brought into the mechanism, closing a route by which the carbon content of inputs could be understated.
  • A replacement for the rule allowing goods to be removed from CBAM’s scope during price shocks: instead of delisting, CBAM revenues from the goods concerned would be temporarily redirected to the affected sectors.
  • Simplified reporting for least-developed countries, and an exemption for electricity flows from non-EU countries that grid operators use to maintain network stability.

What Happens Next: A 457 Versus 200 Fight

The Council adopted its position in June, and it also goes beyond the Commission’s 180 products, but only to about 200 additional metal-intensive industrial, construction and electrical equipment products. The gap between Parliament’s 457 and the Council’s 200 will be one of the central issues in the upcoming trilogue negotiations.

Two scenarios matter for planning. If the final list lands close to the Council position, the compliance burden concentrates on metal-intensive industrial goods, and the administrative build-out stays manageable. If Parliament’s broader list survives, whole categories of clean-tech hardware, including solar panels and heat pumps, acquire a carbon cost at the EU border, with consequences for procurement strategies well beyond the steel and aluminium value chains.

Implications for Importers, Exporters and Buyers

For EU importers of manufactured goods, the vote is a signal to stop treating CBAM as a raw-materials problem. Any product with significant steel or aluminium content is now a candidate for future scope, and the anti-circumvention package means that re-engineering a product minimally to escape the codes is a deteriorating strategy.

For exporters into the EU, the operational question shifts from “is my product covered” to “can I document embedded emissions if it becomes covered.” Companies that have built verified emissions data for CBAM’s current six sectors will have a template; those relying on default values face both higher costs and more scrutiny, since the revised rules give authorities more power to examine the composition of imported goods.

One gap remains unresolved on the pricing side. A Brussels-based think tank this week urged the Commission to publish the values and methodology for calculating the default carbon price under CBAM before the end of the year, arguing that importers cannot price their exposure without them.

What to Watch

Three markers will define the file over the coming months. First, the trilogue outcome on product scope: whether the final list converges toward 200 or toward 457. Second, the Commission’s response on default carbon price values, due by year-end if the pressure holds. Third, the treatment of pre-consumer scrap and the “slightly modified” threshold in the final text, which will determine how much room importers have to optimise product composition without triggering circumvention findings.
