EU manufacturers could see changes in both import competition and production costs under the proposed downstream expansion of the Carbon Border Adjustment Mechanism (CBAM). The potential benefit depends on a company’s position in the supply chain, its sourcing approach, and the share of output sold outside the EU. In parallel, foreign components used in production could become more expensive.
A European fabricator competing with imported metal products could benefit if those imports face a carbon cost comparable to domestic production. A machinery producer buying the same metal products as inputs could face higher landed costs instead. These outcomes can occur within the same industrial group, affecting incentives for sourcing, pricing and investment decisions.
Commission modelling links downstream CBAM to input prices and exports
The European Commission’s modelling highlights a tension between market protection and export effects. Its analysis indicates that extending CBAM downstream can increase the price of certain imported inputs. It also projects a marginal impact on the export competitiveness of finished goods manufactured in the EU.
Protection in the European market would not automatically offset competitive pressure in countries without an equivalent carbon border charge. A manufacturer could gain from reduced import cost pressure at home while becoming less competitive abroad if its own production costs rise. The outcome would depend on where orders are won and how costs change across markets.
The European Automobile Manufacturers’ Association (ACEA) has raised concerns about the proposed expansion’s breadth and timing. It has also questioned the transparency of product selection. The automotive supply chain illustrates complexity because components can cross borders through multiple manufacturing stages before being incorporated into a finished vehicle.
For manufacturers, implications would depend on which components fall within the final scope of coverage. Additional costs would also depend on how they are transmitted through contracts. Whether alternative sources can meet technical specifications and delivery requirements would further shape practical effects.
Supplier changes involve tooling, qualification and compliance administration
Purchasing teams would need to compare the full cost of switching suppliers, including tooling, quality assurance, logistics and production qualification. Shifting to an EU-based source may reduce some customs and carbon-related complexity. It could also require higher manufacturing expenditure or access to additional production capacity.
Keeping an established foreign supplier may remain cheaper even after accounting for additional CBAM exposure. The result would depend on the supplier’s underlying cost base and the applicable emissions calculation. It would also hinge on whether the buyer can negotiate prices or pass costs on to customers.
Administrative burden would vary by company size. Larger manufacturers could distribute compliance systems across larger purchasing volumes, while smaller buyers may face relatively high administrative costs for limited imports. Complex bills of materials could add to this burden, potentially increasing reliance on distributors and procurement intermediaries.
Cost pass-through depends on contracts, margins and substitutes
The extent to which CBAM-related costs reach end customers remains uncertain. Importers may attempt to recover additional expenses through higher selling prices. Their ability to do so would depend on contract terms and competitive conditions in each market.
Where demand is weak or competing suppliers can absorb costs more easily, importers may have to accept lower margins. They may also seek lower purchase prices from overseas suppliers, shifting part of financial pressure back along the supply chain. The distribution of costs would therefore reflect more than regulatory calculations alone.
Bargaining power, market conditions and availability of substitutes would influence how costs are shared across actors. These factors would determine whether pricing adjustments occur upstream with suppliers or downstream with customers. They would also affect how quickly companies can respond to changes in relative input costs.
Domestic protection and export exposure may diverge within groups
Manufacturers are expected to assess domestic sales effects separately from export orders. A group-wide average could conceal uneven exposure between business units. One part of a group could benefit from greater protection while another faces higher input costs without equivalent protection in destination markets.
Product-level cost analysis is described as a clearer basis for pricing, supplier negotiations and investment decisions. It can help identify which products might gain from reduced import competition and which could become more expensive to manufacture. It can also support assessment of where alternative sourcing could improve competitiveness.
The same approach is described as relevant when evaluating proposed factories in Europe. Greater protection from competing imports could strengthen the commercial case for European component production. However, any project would still need sufficient demand and competitive operating costs, since policy advantage cannot replace customer commitments or resolve low capacity utilisation.
The central commercial issue is whether additional protection in the EU market outweighs higher input costs and any resulting loss of export competitiveness. For a European manufacturer purchasing foreign components, this balance could differ from that faced by a domestic supplier competing against the same imports.
