Serbian Steel Exporters Face Greater CBAM Exposure from Precursor Emissions

Steel processors in Serbia and the wider Western Balkans need to assess the embedded emissions of purchased steel inputs alongside factory-level decarbonisation measures as they prepare documentation under the EU’s Carbon Border Adjustment Mechanism (CBAM). Renewable electricity and rooftop solar can reduce operating costs and improve broader product-carbon performance, but emissions inherited from precursor materials can have a greater influence on the regulatory treatment of many covered iron and steel products.

Production Routes Determine Embedded Emissions

The assessment begins with the production route and the precursor materials incorporated into each covered product. Companies involved in steel rolling, drawing, machining and fabrication need to establish how emissions from those inputs are attributed to the final goods.

The applicable treatment depends on the Combined Nomenclature (CN) code and the production process. Under the definitive-period methodology, many downstream finishing activities are treated differently from primary iron and steel production, while emissions associated with upstream precursors may remain embedded in the finished product.

This distinction is particularly relevant to Serbia’s steel value chain. A processor can operate an energy-efficient workshop and purchase renewable electricity while the emissions associated with its purchased steel remain the largest component of its reported embedded emissions. Procurement decisions therefore need to account for supplier emissions data, production routes, material yield and verification quality, in addition to purchase prices and delivery conditions.

Procurement and Material Yield Affect Carbon Intensity

Purchasing steel becomes a direct carbon-control function when processors need reliable evidence for their CBAM calculations. Companies buying coils, billets, slabs and other steel inputs should identify the trader, material grade and, where actual emissions values are used, the producing installation and relevant verified emissions information.

Purchases made through intermediaries can create documentation gaps if the required information about the original producer is unavailable. In those circumstances, a processor may have to rely on less favourable information even if the steel was manufactured using a comparatively efficient production process.

Material yield is another important determinant of embedded emissions intensity. If a process consumes 1,000 tonnes of precursor material and produces only 900 tonnes of saleable output, the upstream emissions are distributed across a smaller volume of finished products. Scrap may retain commercial value and may be suitable for recycling, but material quantities entering the relevant production process must still be accounted for under the prescribed methodology.

For steel service centres and fabricators, cutting, slitting, stamping and machining can generate substantial offcuts. Monitoring electricity consumption per tonne alone may therefore fail to capture the carbon impact of material losses. Management systems should track precursor tonnes per tonne of saleable product, alongside energy intensity and scrap revenue.

Electricity Procurement Must Reflect CBAM Treatment

Electricity remains relevant to decarbonisation, but its regulatory role needs to be distinguished from that of precursor emissions. For most covered iron and steel products, indirect emissions from electricity consumption are excluded from the current CBAM treatment, while specific exceptions, including certain agglomerated ores, can carry indirect emissions through the production chain.

Renewable electricity can still improve corporate Scope 2 emissions and customer-facing product carbon footprints while lowering operating costs. The distinction is that electricity procurement should not automatically be treated as the primary CBAM emissions-reduction measure where the applicable methodology gives greater weight to precursor materials.

Material Traceability Connects Procurement to Verification

A practical monitoring, reporting and verification (MRV) system should establish traceability for each relevant material receipt. Records should link the supplier and producer to the material grade, batch, quantity and associated emissions information.

Warehouse movements must preserve that identity or follow a documented mixing rule. Production orders should record material consumption and finished output, allowing the carbon calculation to follow the same chain used for technical quality control and material traceability. This approach connects procurement records with production data and emissions calculations, helping companies demonstrate how reported values relate to the materials used in individual products.

Supplier Contracts and Emissions Data Become Commercial Factors

Supplier negotiations are likely to place greater emphasis on the availability and reliability of emissions information. A steel input carrying a slightly higher purchase price may deliver a stronger commercial result if it comes with reliable, verified emissions data, compared with cheaper material for which the necessary carbon information cannot be obtained.

Buyers should assess material price, physical performance, embedded emissions and data reliability together. Supplier contracts can include requirements for updated emissions information and confidential disclosure to verifiers, without requiring producers to publish sensitive details about their production processes.

EU customers may also place value on documented improvements over time. A Western Balkan processor able to demonstrate declining precursor emissions intensity, improved material yield and controlled data quality can support its position with customers more effectively than one relying exclusively on annual purchases of green electricity. Lower-emission inputs can be combined with efficient production and renewable energy to support broader product-carbon claims.

Verified Data Separates Recycled Content from Emissions Performance

Steel processors should distinguish claims about recycled content from verified data on embedded emissions. A high proportion of scrap can reduce emissions in many production routes, but the actual benefit depends on the producing installation and the methodology applied.

Claims about recycled content should therefore remain separate from the reported CBAM value unless the underlying emissions evidence substantiates the relationship. Where purchasing volumes provide sufficient leverage, processors can introduce supplier scorecards combining price, quality, delivery performance, embedded emissions and data reliability. Over time, these assessments can direct demand towards mills that provide stronger verified information, creating a commercial incentive for upstream emissions reductions.

Production Routes Support Product-Level Differentiation

Integrated steelmakers and processors sourcing material from multiple production routes should compare precursor emissions intensity by supplier, source and product. Inputs produced through a low-emission electric-arc-furnace route may have a different commercial profile from blast-furnace material, but the advantage depends on verified emissions data, product quality requirements and material yield.

Procurement decisions should consequently rely on route-specific evidence rather than a generic “green steel” designation.

The same information can support customer segmentation. Products made using the strongest pool of verified precursor materials can be allocated to buyers prepared to recognise their value, while other material can serve more price-sensitive markets. Physical segregation and material genealogy are necessary to preserve that differentiation through the verification process.
