A proposed 2028 CBAM expansion to selected downstream steel and aluminium products could alter the economics of equipment sourcing in Europe, where manufacturers choose between importing raw materials, fabricated parts or complete machines. The final scope had not been agreed as of October 2026, leaving the goods that could be covered unresolved.
Products competing in the same commercial tender can face different customs classifications, transport costs, documentation requirements and exposure to carbon rules. Under the existing Carbon Border Adjustment Mechanism (CBAM), specified imported metal goods face obligations, while many completed machines remain outside its initial six sectors.
Importers therefore cannot assume that every finished product avoids a charge under current rules, or that every assembled product will fall within a future expansion. The outcome depends on the goods code, the applicable annex and the date of import. The location of manufacturing and assembly can affect the cost comparison as these rules apply to imported materials and products.
Compare costs across the supply chain
Buying steel plate for fabrication in Europe entails local welding, machining, finishing and labour costs. Importing a welded housing shifts those operations abroad and may bring longer lead times, quality-acceptance risks and potential tariff consequences. Importing a complete machine can reduce local manufacturing content while increasing dependence on an overseas supplier for technology support and spare parts.
For a steel-intensive vessel, procurement teams comparing an EU-produced vessel made from imported raw material, one welded abroad, or one delivered within an integrated process package should establish the relevant goods codes and embedded-emissions methodology for each configuration. They should also compare alloy specifications, nondestructive-testing requirements, certificates, delivery conditions, insurance, warranty coverage and plant acceptance.
A low ex-works quotation can lead to a higher installed cost if documentation or tolerances are inadequate. Carbon costs should be included in sourcing comparisons, but they are only one part of the cost and decision.
In a hypothetical example, an EU-made fabricated housing is priced at EUR 900, compared with EUR 810 for an imported housing. The imported offer’s nominal discount is EUR 90, before adding external freight, inspection, inventory financing and a quantified probability of rework. That saving could disappear if a few percent of imported pieces require repair or additional inventory is needed to protect the assembly schedule.
Separate compliance costs from sourcing estimates
An EU supplier may include the cost of EUA purchases and electricity in its quotation even when its product does not attract CBAM on domestic sale. A non-EU competitor may face direct CBAM liability only for a covered item crossing the border, and both competitors may source components from the same Asian factories.
Counting an estimated embedded-carbon shadow price as a legal import tax on an out-of-scope assembly would overstate its costs; ignoring genuine compliance obligations would understate them. The proposed Industrial Accelerator Act is a separate policy variable. Stricter origin or local-content rules associated with procurement support could also strengthen the case for keeping manufacturing stages in Europe, despite higher labour or energy costs.
Management teams should test current customs and CBAM rules, the possible 2028 downstream perimeter, and a downside scenario with higher energy and freight costs. Quality, lead-time and capital requirements should remain part of each scenario.
The expected geographic outcome is not necessarily a wholesale move of manufacturing out of Europe. European factories retain advantages in customer proximity, qualification, design ownership, industrial know-how and aftermarket support; some lower-value fabrication could move abroad while precision processing and final testing stay close to users.
Keeping prototype fabrication and qualification near design teams may accelerate product improvement even when mass production is outsourced. Firms that lose control of welding procedures, machining tolerances and tooling may find it much more expensive to bring assembly back in-house. Carbon reform may shift the cost boundary between locations, while a factory’s decision also depends on whether it seeks to preserve manufacturing know-how and capabilities that are difficult to reacquire.
The sourcing strategy may therefore involve changing where different stages of production take place without losing technical control of the product.
