The European Commission has proposed extending the Carbon Border Adjustment Mechanism (CBAM) to 180 additional steel- and aluminium-intensive downstream goods from 1 January 2028. The Council’s position in June 2026 covered about 200 additional products, while the European Parliament’s September 2026 position proposed a broader list of 457. As of 20 October 2026, negotiations on the final legislation were still ongoing.
The proposed extension targets a potential carbon-leakage route in which production shifts outside the EU while finished goods containing steel or aluminium enter the EU without an equivalent carbon adjustment. Coverage of downstream products is intended to reduce that incentive. For mining, refining and materials-processing projects, the implications extend beyond selling output to the costs of acquiring equipment needed to develop and operate industrial facilities.
Imported machinery and embedded emissions
Mining operations rely on steel-intensive infrastructure such as crushers, mills, conveyors, screens, pumps, tanks, structural steelwork and piping. Projects also use electrical enclosures, mobile machinery, process modules and fabricated components. Refineries and smelters require furnaces, cooling systems, pressure equipment, burners, ducting, materials-handling installations and specialised machinery.
European projects often procure major volumes of this equipment from international manufacturing centres including China, Turkey and India. Procurement comparisons typically include purchase prices, performance guarantees, freight, installation support, spare-parts availability and financing terms. A downstream CBAM extension could add another variable through embedded emissions associated with steel and aluminium contained in imported equipment where relevant products are within the final regulatory scope.
The effect depends on the adopted product list and the calculation methodology used under the final rules. Not every mining machine or equipment package would necessarily fall within coverage. Project developers therefore cannot treat potential additional CBAM costs for 2028 as settled before legislation is adopted.
Development timelines heighten procurement uncertainty
Mining and metallurgical projects commonly span five to ten years for development. Equipment specifications, tendering and purchasing decisions typically occur well before commissioning. A project reaching financial close in 2027 could procure major equipment in 2028 or 2029, potentially bringing purchases within the timeframe of the proposed extension.
Long-term capital expenditure models may need to reflect regulatory uncertainty while negotiations continue. One possible outcome is a shift in supplier rankings if imported equipment priced lower upfront contains substantial quantities of carbon-intensive steel. If such equipment is included in the final CBAM scope, its carbon-adjusted landed cost could exceed the original quotation.
Suppliers using lower-carbon materials could become more competitive once additional costs are reflected. The size of any price difference would depend on which equipment is covered, its material composition and the applicable emissions rules.
EPC contracting and data responsibilities
The proposed extension may affect arrangements among project owners, engineering procurement and construction (EPC) contractors, original equipment manufacturers (OEMs), customs representatives and emissions verifiers. Major equipment purchase agreements and EPC contracts may require explicit provisions covering customs classification, emissions documentation and verification. Contracts may also need mechanisms for allocating costs linked to changes in CBAM legislation.
Where a project company acts as importer of record, it may carry direct import-related obligations while relying on an OEM to provide emissions information about steel and aluminium used in equipment. Manufacturers may not currently collect all data needed for that purpose. This creates an interface risk if the party responsible for meeting regulatory obligations does not control underlying production information required to substantiate emissions claims.
Contracts would therefore need to specify who supplies data, which methodologies apply, how information is verified and how additional costs are allocated if documentation is insufficient or requirements change.
Customs documentation could affect delivery schedules
Documentation requirements could also influence construction and commissioning timelines. Depending on final rules, incomplete emissions information could delay customs clearance or lead to reliance on default values. For projects dependent on timely arrival of large mills, transformers, furnaces or process modules, customs and emissions documentation could become part of the critical path alongside manufacturing, shipping, installation and commissioning.
If delivery is delayed, commercial impacts could extend beyond any direct carbon-related charge tied to CBAM treatment. Project developers would need to coordinate preparation of emissions records with manufacturing schedules and contractual delivery milestones. Supplier data availability would therefore need attention before equipment ships rather than after it reaches the EU border.
Financing models may require a CBAM contingency
Project financing already addresses uncertainties involving steel prices, freight and foreign-exchange movements. If downstream CBAM coverage expands beyond current scope expectations, financial models may also include a separate contingency for potential costs of imported equipment. This exposure may be more relevant where projects rely heavily on imported machinery and have limited financial flexibility.
Unexpected costs could affect project budgets and debt-service coverage depending on the size of equipment packages and how final regulatory treatment applies. Mining companies have multiple procurement responses described as options rather than requirements: increasing sourcing from European manufacturers when feasible; requiring international OEMs to provide verified emissions information for covered metal inputs; favouring suppliers using lower-carbon steel and aluminium; or establishing contractual mechanisms for allocating unforeseen CBAM costs.
OEMs face embedded-material evidence requirements
The extension would also affect machinery manufacturers supplying the European market. OEMs may need to identify origin and carbon intensity for steel plate, castings, aluminium components and other covered inputs incorporated into their products. This differs from calculating a manufacturer’s own factory emissions or electricity footprint because it concerns embedded emissions tied to materials used in equipment.
Chinese machinery suppliers could face particular scrutiny because their products are often competitive on price and financing terms while carbon intensity of underlying steel and aluminium varies considerably. Manufacturers using lower-carbon metals with documented supply chains could be better positioned than competitors unable to substantiate emissions from inputs.
European equipment manufacturers could benefit if reduced price advantages for carbon-intensive imports follow from CBAM-related cost adjustments at the border. They may compete through lifecycle services, proximity to customers, spare-parts availability, digital integration and lower-carbon material inputs. The measure would not remove differences in productivity or high energy costs because its stated purpose is border cost adjustment rather than general subsidy.
Broader trade implications beyond raw materials
The implications are not limited to EU mining projects importing equipment. Mining companies and manufacturers outside the EU could face additional documentation requirements if they export equipment-intensive finished goods to Europe or if their downstream products become covered by expanded CBAM coverage. The change would extend relevance further into industrial value chains beyond direct trade in raw materials and basic metals.
For project owners, engineers, EPC managers and lenders involved in procurement decisions inside Europe’s supply chain context, immediate tasks include screening equipment registers for potentially covered goods. Such assessments can identify supplier country details, metal content of equipment, importer of record status, availability of emissions evidence and how contractual responsibilities are allocated for regulatory obligations.
This screening does not require certainty about the final 2028 product list before orders are placed. It supports identifying exposure while purchase orders and supplier agreements can still be adjusted based on evolving legislation during negotiations.
Steel prices have long been a major variable in mining capital expenditure under project planning assumptions described alongside freight rates and foreign exchange movements. Under the proposed downstream CBAM extension framework discussed here, the emissions intensity of steel used in imported equipment could become an additional factor in procurement decisions and project-cost calculations where relevant products fall within scope.
