Serbian manufacturers that process imported or domestically produced metals into industrial components could face a broader set of EU carbon-border requirements if the proposed expansion of the Carbon Border Adjustment Mechanism (CBAM) is adopted. The changes could add 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.
The effect on Serbian exporters is expected to depend on final product classifications and emissions-calculation methods. It would not be determined solely by whether a manufacturer uses steel or aluminium in production.
Downstream scope and implications for Serbian metalworking
The proposed expansion is relevant to Serbian engineering and metalworking companies positioned between raw-material suppliers and EU manufacturers. These firms purchase coil, profiles, billets, or components, perform fabrication and finishing, and supply customers that value traceability, production flexibility, and short transport times.
Much of the information needed to establish the carbon footprint of a finished product is generated before the Serbian processing stage. Records may be held by an upstream mill in another country, which can create an information gap for Serbian manufacturers and their European customers.
Companies exporting from Serbia may need to separate obligations across two categories of products. Certain Serbian steel and aluminium products already fall within CBAM’s existing scope, while some machinery parts and finished industrial goods may be covered only if the downstream expansion is adopted.
Manufacturers selling products in both categories are expected to map their Combined Nomenclature (CN) codes separately. They would also need to distinguish current obligations from potential future liabilities. Proposed requirements should not be applied retroactively to products that are not currently covered.
Precursor emissions data and traceability requirements
Where a finished component includes steel produced in China, Türkiye, or another third country, EU importers may require precursor-emissions information under the applicable methodology. A Serbian invoice or certificate of non-preferential origin would not necessarily show the emissions embedded in the metal.
Depending on product rules and final requirements, supporting documentation may need to connect the original steel mill, material batch, production route, and allocation of material to the finished product supplied to an EU customer. This documentation linkage is intended to reflect how precursor inputs relate to the exported component.
The requirement can be difficult for manufacturers that buy materials through intermediaries or receive only general environmental declarations from suppliers. Without access to appropriate upstream records, they may struggle to provide information needed for products covered under CBAM rules.
Contracting dynamics and investment planning
The proposed changes could affect commercial negotiations 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 may be better positioned to secure contracts than competitors relying on generic supplier declarations. The extent of this advantage depends on final rules and the information required for specific products.
Potential carbon-related costs could also influence industrial investment decisions. Companies planning new presses, extrusion lines, machining centres, and metal-fabrication capacity would need to assess whether investments would remain competitive under several plausible outcomes of downstream CBAM negotiations.
Banks financing export-oriented manufacturing capacity may seek clearer information about product-code exposure, supplier concentration, and contractual rights to obtain emissions data. Such information could help them evaluate resilience for projects that depend heavily on continued access to the EU market.
Embedding compliance in procurement and supplier management
For Serbian manufacturers, preparation may involve integrating customs classification, bills-of-materials traceability, and emissions documentation into routine procurement and supplier-management processes. This approach would reduce reliance on last-minute certification activities.
Integrating these elements can help identify missing information, clarify responsibilities with upstream suppliers, and respond more quickly when customers request supporting records. It can also preserve operational flexibility while EU institutions negotiate final product coverage and calculation requirements.
The eventual impact will depend on legislation adopted in Brussels. In the meantime, product classification, precursor traceability, and access to verifiable emissions data are becoming increasingly relevant for Serbian manufacturers seeking to maintain and expand industrial supply relationships with European customers.
