EU manufacturers could gain protection against imports of finished goods under the proposed downstream expansion of the Carbon Border Adjustment Mechanism (CBAM) while facing higher costs for foreign components used in their own production. The net effect will depend on each company’s position in the supply chain, its sourcing strategy and the share of output sold outside the EU.
A European fabricator competing directly with imported metal products could benefit if competing imports face a comparable carbon cost. A machinery producer purchasing those same products as inputs, however, could face higher landed costs. Both effects can occur within the same industrial group, creating competing incentives for sourcing, pricing and investment.
Protection in Europe May Come at an Export Cost
The European Commission’s modelling recognises this tension. Its analysis indicates that extending CBAM downstream can increase the price of certain imported inputs and marginally affect the export competitiveness of finished goods manufactured in the EU.
Protection in the European market does not automatically compensate manufacturers competing for orders in markets without an equivalent carbon border charge. A company may gain from reduced cost pressure from imports at home while becoming less competitive abroad if its own production costs rise.
The European Automobile Manufacturers’ Association (ACEA) has raised concerns about the proposed expansion’s breadth and timing, as well as the transparency of product selection. The automotive supply chain illustrates the complexity because components can cross borders through several manufacturing stages before being incorporated into a finished vehicle.
For manufacturers, the implications will depend on which components fall within the final scope, how additional costs are transmitted through contracts and whether alternative sources can meet technical and delivery requirements.
Switching Suppliers Involves More Than Carbon Costs
Purchasing departments need to compare the full cost of changing suppliers, including tooling, quality assurance, logistics and production qualification. Moving to an EU-based source may reduce some customs and carbon-related complexity, but it could also require higher manufacturing expenditure or access to additional production capacity.
Retaining an established foreign supplier may remain the cheaper option even after accounting for additional CBAM exposure. The outcome depends on the supplier’s underlying cost base, the applicable emissions calculation and the buyer’s ability to negotiate prices or pass costs on to customers.
The administrative burden also varies by company size. Large manufacturers can distribute compliance systems across substantial purchasing volumes, whereas smaller buyers may face relatively high administrative costs for limited imports. Complex bills of materials can add to that burden, potentially increasing reliance on distributors and procurement intermediaries.
Cost Pass-Through Will Depend on Market Conditions
The extent to which CBAM-related costs reach end customers remains another uncertainty. Importers may seek to recover additional expenses through higher selling prices, but their ability to do so depends on contract terms and competitive conditions.
Where demand is weak or competing suppliers can absorb costs more easily, importers may have to accept lower margins. They may also seek to negotiate lower purchase prices with overseas suppliers, shifting part of the financial pressure back along the supply chain.
The final distribution of costs will therefore depend not only on the regulatory calculation but also on bargaining power, market conditions and the availability of substitutes.
Group-Level Averages Can Conceal Uneven Exposure
Manufacturers should assess the effects on domestic sales and export orders separately. A group-wide average can conceal a domestic business that benefits from greater protection and an export division that faces higher input costs without equivalent protection in its destination markets.
Product-level cost analysis provides a clearer basis for pricing, supplier negotiations and investment decisions. It can help companies identify which products may gain from reduced import competition, which could become more expensive to manufacture and where alternative sourcing could improve competitiveness.
The same discipline is needed when evaluating proposed factories. Greater protection from competing imports could strengthen the commercial case for European component production, but a project would still need sufficient demand and competitive operating costs. A policy advantage cannot replace customer commitments or resolve low capacity utilisation.
The central commercial question is whether the value of additional protection in the EU market will outweigh the cost of more expensive inputs and any resulting loss of export competitiveness. For a European manufacturer purchasing foreign components, the answer may differ sharply from that for a domestic supplier competing against the same imports.
