Serbia entered the European Union’s definitive Carbon Border Adjustment Mechanism period on 1 January 2026 with a sizeable but relatively concentrated exposure. The immediate compliance perimeter is centred on iron and steel, aluminium, electricity, fertilisers and cement, industries dominated by a manageable number of large installations and exporters. That structure will change markedly under the EU’s announced downstream expansion, which is expected to bring machinery, electrical equipment, commercial-vehicle components, household appliances and other metal-intensive manufactured products into the mechanism from 1 January 2028.
Measured against full-year 2025 trade, Serbian exports to the EU falling within the legally effective CBAM scope were worth approximately €2.07 billion. The European Commission’s proposed downstream list would add an estimated €894 million, taking the combined measurable export envelope to around €2.97 billion. That is equivalent to approximately 15.1 per cent of Serbia’s goods exports to the EU, before allowing for a potentially broader final list emerging from negotiations among the European Commission, the Council and the European Parliament.
This is not an estimate of Serbia’s eventual CBAM charge. Trade value and carbon liability are different measures. The financial obligation depends on the embedded emissions of each product, the prevailing EU Emissions Trading System price, the gradual reduction of free allocations for EU producers and any recognised carbon price already paid in the country of origin. Yet the trade value matters commercially because it identifies the export revenue that could become dependent on verified emissions, production records, precursor traceability and reliable data exchange with authorised EU CBAM declarants.
The shift is also happening while Serbia’s trade with the EU and its reliance on Asian and Turkish industrial inputs are rising. During January–May 2026, Serbian goods exports increased by 16.6 per cent year on year to $17.17 billion. Exports to the EU rose by 18.7 per cent to $10.84 billion, lifting the bloc’s share of Serbian exports from 62.0 per cent to 63.1 per cent. Imports increased by 9.3 per cent to $20.66 billion, including $3.15 billion from China, up 16.9 per cent, and $1.08 billion from Türkiye, up 17.5 per cent.
The pattern places CBAM at the intersection of three important parts of Serbia’s economic model: access to the EU market, foreign-owned export manufacturing and the growing use of non-EU equipment and intermediate materials. The first stage of CBAM is concentrated among large industrial companies. The second stage reaches a wider manufacturing network whose margins, financing and customer relationships are often built around long-term supply contracts with European buyers.
Serbia exported goods worth approximately €33 billion in 2025, while imports reached about €41.8 billion. Exports to the EU were worth approximately €19.7 billion. Products in the current CBAM scope therefore represented around 10.5 per cent of Serbia’s EU-bound merchandise exports.
Iron and steel formed the largest component, with exports estimated at €912 million, or 44 per cent of the current CBAM envelope. Electricity followed at approximately €531 million, representing 25.6 per cent, while aluminium contributed around €519 million, or 25.1 per cent. Fertiliser exports were worth approximately €104 million, with cement at roughly €5 million and hydrogen below €1 million.
The value of current-scope exports increased from an estimated €1.82 billion in 2024, implying annual growth of roughly 14 per cent. This makes the immediate compliance issue materially larger than it was during the transitional reporting period, when there was no certificate-purchase obligation and many companies treated CBAM as an environmental disclosure exercise rather than a market-access and cash-flow control.
The main corporate exposure is concentrated around several identifiable industrial systems. HBIS Serbia’s Smederevo steelworks sits at the centre of the iron and steel category, supported by Metalfer Steel Mill in Sremska Mitrovica and Serbian producers of rolled products, tubes, structures, fasteners and fabricated steel components. Aluminium exposure is closely associated with Impol Seval and downstream processors. Fertiliser exposure is concentrated around Elixir Group’s production complexes in Prahovo and Šabac. Electricity exposure involves EPS, regional electricity traders and cross-border physical flows. The cement segment includes Lafarge Serbia, Moravacem and Titan Cementara Kosjerić.
Romania was Serbia’s largest current-scope EU market in 2025, with an estimated €420 million of covered exports. Czechia followed with €218 million, Hungary with €212 million, Germany with €186 million, Bulgaria with €181 million, Croatia with €162 million, Poland with €153 million, Italy with €133 million, Slovakia with €110 million and Austria with approximately €76 million.
Romania and Hungary have unusually large shares because the existing scope is heavily influenced by electricity and regional metals trade. Germany, Italy, Czechia, Poland and Slovakia are more closely connected to Serbia’s manufacturing supply chains. That distinction becomes much more important once the mechanism moves downstream.
The Commission’s December 2025 proposal envisages adding approximately 180 steel- and aluminium-intensive product lines from 1 January 2028. About 94 per cent of these goods are industrial supply-chain products, with average steel and aluminium content estimated at 79 per cent. Household products represent only around 6 per cent of the proposed expansion.
The list includes fabricated metal goods such as nails, staples, fencing, wire ropes, springs, cast products, caps, lids and fittings. It also reaches diesel engines, fuel and cooling pumps, centrifugal pumps and furnace burners; refrigerators and their components, washing machines, dryers and cooling towers; winches, hoists, jacks, cranes, conveyors, industrial robots and handling machinery; agricultural, construction, foundry, stone-working and mineral-processing equipment; motors, transformers, inductors, welding equipment and selected electrical conductors; goods vehicles, chassis, bodies, gearboxes, wheels, suspension systems and radiators; and selected medical instruments, metal furniture and prefabricated structures.
On Serbia’s 2025 trade pattern, these categories add approximately €894 million of EU-bound exports to the measurable CBAM perimeter. The increase is equivalent to around 43 per cent of the current legally effective exposure. The combined value of existing and proposed products reaches approximately €2.97 billion, or 15.1 per cent of Serbia’s exports to the EU.
The figure remains an analytical estimate because Serbian merchandise statistics are generally available at HS6 level, while parts of the European proposal rely on more detailed CN8 codes and “ex” definitions covering only products with specified steel or aluminium content. It also does not capture the full potential impact of the Council’s negotiating position agreed on 12 June 2026, which refined and broadened the proposed perimeter. The European Parliament’s position and the subsequent trilogue will determine the final list, definitions and implementation details.
The market structure changes sharply under the proposed scope. Germany becomes the largest destination for potentially covered downstream Serbian goods, with estimated exports of approximately €270 million. The Netherlands follows at €129 million, Slovenia at €107 million, Hungary at €69 million, Italy at €64 million, Poland at €45 million, Slovakia at €33 million, Croatia and Austria at approximately €28 million each, and Czechia at around €21 million.
The movement from Romania towards Germany as the leading exposure market captures the wider economic shift. Current CBAM is largely an upstream metals and electricity mechanism. The downstream phase is much more closely connected to the foreign-owned manufacturing base that has powered Serbian export growth.
Companies with relevant Serbian production profiles include ZF Serbia, Bosch, Siemens Mobility, Grundfos, Johnson Electric, Hisense/Gorenje, Metalac and a broad network of automotive, electrical, machinery and fabricated-metal suppliers operating around Kragujevac, Novi Sad, Niš, Pančevo, Subotica and Belgrade. Coverage cannot be determined at company level without checking the exact customs code and physical composition of each exported product. A manufacturer may produce several product families, only some of which fall within the final CBAM list.
That product-level distinction will become central to contracts and financing. EU buyers will not accept a general corporate carbon figure where CBAM requires installation, product and production-route data. The exporter must establish which installation produced the goods, what precursor materials were consumed, which emissions were embedded in those precursors and how the relevant emissions were allocated to the exported quantity.
Serbia’s growing imports from China and Türkiye add another layer of complexity. In 2025, Serbian imports from China were worth approximately €6.43 billion, while imports from Türkiye reached about €2.19 billion. Goods already falling under current CBAM product codes represented an estimated €464 million of Chinese imports and €382 million of Turkish imports.
The Commission’s proposed downstream categories add approximately €346 million of imports from China and €183 million from Türkiye. The combined current and proposed product-code exposure is therefore about €810 million for China and €565 million for Türkiye, producing a total precursor and re-export perimeter of approximately €1.38 billion.
These values do not demonstrate that every imported item is incorporated into an EU-bound Serbian product. Public customs statistics cannot connect a specific imported steel coil, aluminium profile, casting, motor, pump or transformer to the finished export batch in which it is ultimately used. The figures instead establish the maximum trade perimeter within which origin, precursor emissions and transformation rules could become relevant.
Serbia does not pay EU CBAM when Chinese or Turkish goods enter the Serbian market. Exposure arises when a covered product is re-exported to the EU, when an imported material becomes a precursor in a complex Serbian product, or when the processing undertaken in Serbia is insufficient to confer Serbian non-preferential origin.
Repacking, relabelling, minor finishing and simple assembly do not automatically convert Chinese or Turkish origin into Serbian origin. The strengthened EU anti-circumvention framework will allow authorities to request evidence that the declared installation genuinely produced the goods during the stated production period. A Serbian warehouse, distributor or light-assembly operation cannot rely on a Serbian invoice as proof of Serbian origin or Serbian embedded emissions.
The issue is different where a Serbian factory performs genuine substantial transformation. The finished product may acquire Serbian origin, but the emissions embedded in covered precursor materials remain relevant to the CBAM calculation for complex goods. A manufacturer using Chinese steel, Turkish fabricated components or aluminium from an undocumented installation may be required to apply conservative default emissions, even where the Serbian production stage is relatively efficient.
This creates a control chain extending well beyond the factory gate. Supplier installation data must be connected to the imported lot, customs declaration, material grade and weight. Those records must then be linked to the Serbian company’s internal material code, production order, meter readings, mass balance, finished-product classification and EU shipment. The EU authorised declarant must be able to reconcile the information with the CBAM declaration and, where necessary, the verifier must be able to reproduce the calculation from original evidence.
The principal weakness for many Serbian exporters will not be the absence of a sustainability policy. It will be fragmented operational data. Procurement may hold supplier declarations, production may hold batch records, accounting may hold energy invoices, customs teams may control CN classifications and environmental departments may calculate emissions using different system boundaries. CBAM requires those records to form one auditable data architecture.
A credible pre-verification system therefore begins with the product and production route rather than with a corporate emissions report. It should define the installation boundary, confirm the CN code, identify direct and relevant indirect emissions, map precursor inputs, reconcile physical production with sales and inventory, establish meter ownership and calibration, document calculation factors and create a controlled route for transmitting data to the EU importer.
Chinese and Turkish supplier contracts will increasingly need emissions-data provisions alongside price, quality and delivery terms. Exporters may require installation identification, production-route descriptions, verified emissions values, data-retention obligations, audit rights and contractual remedies where the supplier cannot provide acceptable evidence. Procurement based only on the lowest ex-works price may become more expensive once default emissions, CBAM certificates and customer-retention risk are included.
The financing consequences extend beyond the direct cost of carbon certificates. EU customers may introduce CBAM pass-through clauses, retain part of the invoice pending verification, impose default-emissions adjustments or transfer administrative and certificate costs to the Serbian supplier. Long-term supply agreements may include termination rights when data are incomplete or when the carbon intensity exceeds an agreed threshold.
Banks financing Serbian exporters will increasingly need to examine whether EU receivables remain eligible, collectible and protected from carbon-related deductions. Revolving facilities and borrowing-base structures could distinguish between receivables supported by verified CBAM data and those exposed to uncertain default values. Investment lenders will scrutinise whether proposed capex improves measurable emissions, preserves EU contracts and can be demonstrated through metering and verification.
The strongest response is not necessarily an immediate large decarbonisation programme. It is the creation of a controlled baseline. Correct customs classification, installation-level emissions, calibrated meters, reconciled mass and energy balances, documented production routes and contractual access to precursor data allow management and lenders to distinguish among a compliance gap, an operational-efficiency investment and a larger capital programme.
Once that baseline exists, companies can evaluate electrification, waste-heat recovery, process optimisation, renewable electricity procurement, low-carbon precursor sourcing and production-route changes using credible financial assumptions. A PPA, guarantee of origin or I-REC cannot independently establish CBAM compliance. Renewable electricity needs to sit within a consistent contractual, metering and verification structure, particularly where indirect emissions are relevant or where customers require a broader product-carbon-footprint standard.
Serbia’s immediate priority remains the €2.07 billion already inside the definitive mechanism. The next priority is the manufacturing perimeter approaching €894 million under the Commission proposal. The third is the €1.38 billionchannel of Chinese and Turkish products that could enter re-export, precursor or origin calculations.
The announced expansion moves CBAM beyond the steelworks, aluminium processor, fertiliser plant and power producer. It reaches the part of Serbia’s economy most closely associated with foreign investment, industrial employment and integration into European supply chains. With approximately €2.97 billion of EU-bound trade already visible within the combined current and proposed perimeter, carbon data quality is becoming part of Serbian industrial credit quality, supplier qualification and export bankability.
