The European Union is moving toward a Carbon Border Adjustment Mechanism (CBAM) framework that could widen carbon-related compliance from covered commodities to selected downstream goods. For Türkiye, whose industrial supply chains are closely connected to European manufacturing, the shift would increase the range of exports potentially subject to future emissions scrutiny. While the details are still being negotiated, the direction of travel is already shaping how buyers may seek information from suppliers.
The European Commission has proposed extending CBAM to downstream products containing significant steel or aluminium content starting in 2028. The initial scope would cover 180 product categories, with the European Parliament supporting a broader approach and the Council proposing its own adjustments. As of 12 October 2026, the proposed additions remain under negotiation and are not current import obligations.
That timeline matters for exporters because compliance expectations can emerge before legal requirements take effect. In practice, EU importers and manufacturers may begin aligning procurement processes with anticipated reporting needs as the legislative package progresses through Brussels.
Downstream supply chains serving EU manufacturers face tighter checks
Potential exposure is expected to concentrate in supply chains feeding Germany, Italy and other EU manufacturing centres. Turkish firms provide metal mountings, fabricated products, engineering components and machinery-related goods that may include steel or aluminium produced at separate industrial installations. Under an expanded CBAM framework, importers may need to connect the finished component to its metal precursors, the relevant manufacturing processes and the information provided to end customers in the EU.
For Türkiye’s exporters, this raises questions about how embedded emissions data will be assembled across multi-stage production. The country benefits from relatively short freight times to European markets, established customer relationships, production flexibility and the ability to customise products. However, carbon compliance could shift attention away from logistics and pricing alone toward traceability and documentation.
Basic steel performance already shows how competitive pressure can build before new rules fully land. EUROFER recorded a 16% year-on-year decline in Turkish finished-steel shipments in the first half of 2026, even though Türkiye remained the EU’s largest supplier by volume share at 15.7% of finished-steel imports. Extending CBAM considerations beyond commodity trade could broaden where such pressures are felt across Türkiye’s industrial export base.
Supplier-specific emissions evidence becomes central
Assessing potential carbon exposure using a single national emissions factor would not capture differences across producers. Steel output depends on different furnace routes, while aluminium can be produced through primary or secondary processes, producing distinct emissions profiles. A fabricator’s own electricity consumption also does not automatically reflect the embedded emissions of purchased metal.
Instead, relevant installation information and precursor data would need to be documented using methods that will apply under the expanded rules. For Turkish exporters, access to upstream production records could therefore become part of maintaining European customer relationships as requests for emissions information increase during negotiations.
Companies able to identify material origins and provide reliable emissions information may be better positioned to respond to buyer queries. This could matter even before a specific finished product becomes subject to a CBAM certificate obligation.
Procurement terms and investment plans may be renegotiated
Commercial arrangements could start changing ahead of any final entry into force. European manufacturers may seek contractual provisions that allow them to request emissions records, obtain audited material declarations and renegotiate prices if regulatory requirements shift. Turkish suppliers that can provide requested information promptly could gain an advantage in procurement decisions during this transition period.
The proposal also introduces implications for investment and sourcing strategy within Türkiye’s industrial sector. Manufacturers securing verified lower-emission steel or aluminium may be better placed to negotiate longer-term supply agreements with selected mills while preserving existing European contracts. Conversely, if EU buyers seek price reductions tied to anticipated carbon-related costs, processors with limited margins could face additional commercial pressure.
Brussels negotiations will determine how far compliance extends
The eventual impact will depend on negotiations in Brussels, final product classifications and the capacity of Turkish industry to organise and verify upstream emissions data. Until rules are adopted, exporters and importers must separate potential future exposure from obligations already in force under the current CBAM scope.
Türkiye’s geographic proximity to Europe and established industrial links remain important competitive advantages. Still, under a broader CBAM framework, logistics and pricing may no longer be sufficient to determine the most attractive supply offer for EU buyers. Material traceability, emissions documentation and the ability to substantiate production data are likely to become increasingly influential in European procurement decisions as downstream coverage is defined.
Analytical synthesis: The proposed extension of CBAM from covered steel and aluminium commodities toward selected downstream products containing significant metal content would broaden carbon-related sourcing decisions affecting Türkiye’s industrial exports. With scope still under negotiation as of 12 October 2026, companies’ near-term advantage is likely tied less to freight proximity than to access to upstream records, supplier-specific emissions evidence and readiness to support contractual requests for audited declarations and price renegotiations as regulatory expectations evolve.
