Serbian manufacturers processing imported or domestically produced metals into industrial components could face a broader range of EU carbon-border requirements if the proposed expansion of the Carbon Border Adjustment Mechanism (CBAM) is adopted. The changes could introduce additional cost considerations and documentation requirements for exporters supplying European customers.
The European Commission has proposed extending CBAM to selected downstream products with significant steel or aluminium content from 2028. In September 2026, the European Parliament adopted amendments supporting a substantially broader product list, while the Council maintains a separate negotiating position. These proposals have not yet become enacted law. Their impact on Serbian exporters will depend on the final product classifications and emissions-calculation methods, rather than simply on whether a manufacturer uses steel or aluminium.
Serbian metalworking supply chains face new data demands
The proposed expansion is relevant to Serbian engineering and metalworking companies positioned between raw-material suppliers and EU manufacturers. These businesses purchase coil, profiles, billets or components, carry out fabrication and finishing, and supply customers that value traceability, production flexibility and short transport times.
However, much of the information needed to establish the carbon footprint of a finished product originates before the Serbian processing stage. Relevant records may be held by an upstream mill in another country, creating a potential information gap for Serbian manufacturers and their European customers.
Companies will need to distinguish between two categories of exports. Certain Serbian steel and aluminium products already fall within CBAM’s existing scope, while some machinery parts and finished industrial goods may become covered only if the proposed downstream expansion is adopted.
Manufacturers selling products in both categories should map their Combined Nomenclature (CN) codes separately and distinguish existing obligations from potential future liabilities. Proposed requirements should not be applied retroactively to products that are not currently covered.
Precursor emissions and product traceability
Where a finished component incorporates steel produced in China, Türkiye or another third country, the EU importer may need relevant precursor-emissions information under the applicable methodology. A Serbian invoice or certificate of non-preferential origin would not necessarily establish the emissions embedded in the metal.
Depending on the product and final rules, the supporting documentation may need to link the original steel mill, material batch, production route and allocation of the material to the finished product supplied to the EU customer.
This creates a practical challenge for manufacturers that purchase materials through intermediaries or receive only general environmental declarations from suppliers. Without access to appropriate upstream records, they may struggle to provide the information required for products covered by the applicable CBAM rules.
Export competitiveness and investment decisions
The proposed changes could create a commercial tension for Serbian fabricators. Their proximity to European customers and ability to offer flexible production can be advantages, but EU buyers may increasingly request detailed upstream emissions data while resisting higher purchase prices.
Manufacturers with reliable purchasing records, traceable material batches and access to verifiable mill emissions data could therefore be better positioned to secure contracts than competitors relying on generic supplier declarations. The extent of this advantage will depend on the final rules and the information required for individual products.
Potential carbon-related costs could also influence industrial investment decisions. Companies planning new presses, extrusion lines, machining centres and metal-fabrication capacity should assess whether their proposed investments would remain competitive under several plausible outcomes of the downstream CBAM negotiations.
Banks financing export-oriented manufacturing capacity may also seek clearer information about product-code exposure, supplier concentration and contractual rights to obtain emissions data. Such information could help them assess the resilience of projects that depend heavily on continued access to the EU market.
Integrating compliance into supplier management
For Serbian manufacturers, the most effective preparation may be to integrate customs classification, bills-of-materials traceability and emissions documentation into routine procurement and supplier-management processes, rather than relying on a last-minute certification exercise.
This approach can help businesses identify missing information, establish responsibilities with upstream suppliers and respond more quickly when customers request supporting records. It can also preserve flexibility while EU institutions negotiate the final product list and calculation requirements.
The eventual impact will depend on the legislation adopted in Brussels. Nevertheless, product classification, precursor traceability and access to verifiable emissions data are becoming increasingly relevant to Serbian manufacturers seeking to maintain and expand their industrial supply relationships with European customers.
