The European Commission’s new aluminium guidance leaves Serbia’s carbon-intensive electricity largely outside the CBAM calculation. For Impol Seval, Alumil YU Industry and MTC NISSAL, however, the commercial contest will be decided by raw-material traceability, direct furnace emissions and the credibility of supplier data.
The European Commission’s sector-specific guidance for aluminium resolves one of the largest uncertainties facing Serbian producers selling into the European Union. Electricity consumption, despite its importance to aluminium production and Serbia’s dependence on lignite-fired generation, is not included in the embedded emissions of aluminium goods covered by the Carbon Border Adjustment Mechanism. Only direct emissions are counted.
That is genuine relief, but not an exemption. The guidance transfers much of the carbon exposure away from the Serbian power system and into the aluminium entering each factory: the slabs, billets and unwrought metal subsequently rolled, extruded or formed into products for the European market. Serbian manufacturers may therefore discover that the decisive CBAM variable is not the emissions generated inside their own plants, but whether they can document the origin, production route and verified carbon intensity of their feedstock.
The Commission’s Guidance Document 5E, published on 14 August 2026, covers unwrought aluminium and an extensive range of downstream goods, including powders, bars, profiles, wire, plates, sheets, strip, foil, tubes, structures, containers and other aluminium articles. Aluminium scrap under CN 7602 and household articles under CN 7615 remain outside the listed scope. The document is explanatory rather than legally binding, but it provides the clearest operational interpretation yet of how aluminium emissions should be calculated during the definitive CBAM period. European Commission, Guidance Document 5E
For Serbia, the stakes are substantial. The country exported approximately $853.7 million of aluminium and aluminium articles in 2025. The EU accounted for about $505.7 million, or 59.2 per cent, of that trade. The Czech Republic, Germany and France alone purchased roughly $346.2 million, equivalent to more than two-thirds of Serbia’s EU-bound aluminium exports. Plates, sheets and strip represented the largest product group, followed by aluminium containers, other articles, structures, bars and profiles.

This export structure reflects Serbia’s position in the European aluminium chain. The country is not a large primary aluminium producer. Its industrial strengths are rolling, extrusion, recycling, alloy preparation, fabrication and surface treatment. That distinction matters because the Commission applies different accounting rules to primary production, secondary melting and downstream manufacturing.
A primary smelter must report carbon dioxide from anodes and paste, fuel combustion, flue-gas treatment and perfluorocarbons such as CF4 and C2F6. Secondary aluminium production reports direct fuel emissions and treats scrap as having zero embedded emissions. A rolling or extrusion plant, meanwhile, manufactures a “complex good”. Its reported emissions combine the direct emissions of the processing operation with the embedded emissions of the unwrought aluminium used as a precursor.
For Serbian rolling and extrusion companies, the precursor can dominate the result. A factory may operate efficient furnaces, install modern burners and maintain disciplined energy management, yet still deliver a high-CBAM product if it purchases carbon-intensive primary aluminium without verified installation data. Conversely, a producer with substantial recycled content or documented low-carbon billets can report a significantly lower embedded-emissions value even when its Serbian electricity consumption remains considerable.
Impol Seval, based in Sevojno, is the clearest test case. The company is 70 per cent owned by Slovenia’s Impol Groupand represents one of Serbia’s most important aluminium processing assets. Its industrial system includes casting and recycling operations as well as hot and cold rolling, allowing the plant to manufacture higher-value rolled products rather than merely trade unwrought metal.
In 2025, Impol Seval produced 47,577.9 tonnes, down 9.6 per cent from 52,632 tonnes a year earlier. It consumed approximately 15.08 million cubic metres of natural gas and 39.50 GWh of electricity. The company reported direct, Scope 1 emissions of 28,267 tonnes of CO₂ equivalent, or 0.594 tonnes per tonne of production. Its location-based Scope 2 emissions were higher, at 43,415 tonnes, reflecting the disclosed Serbian grid factor of 1.099 kilograms of CO₂ per kWh. Impol Group 2025 annual report
The comparison demonstrates the significance of the Commission’s approach. Electricity represented approximately 61 per cent of Impol Seval’s combined reported Scope 1 and location-based Scope 2 emissions in 2025. Yet those indirect emissions are excluded from the aluminium CBAM calculation under the current guidance. The plant’s disclosed 0.594-tonne Scope 1 intensity is therefore much closer to the starting point for its own processing emissions than the combined site figure of approximately 1.507 tonnes per tonne.
Neither number should be mistaken for a verified CBAM product value. Impol Seval’s corporate emissions inventory and the Commission’s prescribed production-process boundaries are not necessarily identical. The CBAM calculation must also add the embedded emissions of the aluminium precursor, adjusted for the quantity of input required to manufacture one tonne of finished product. Material losses and cutting yields matter because the calculation uses the precursor mass entering production, even where cutting or finishing emissions themselves sit outside the system boundary.
The financial sensitivity is nevertheless instructive. At a hypothetical CBAM certificate price of €75 per tonne of CO₂, an intensity of 0.594 tonnes represents a gross carbon-value equivalent of about €44.55 per tonne of product. Applied to Impol Seval’s entire 2025 production, it would equal approximately €2.12 million. At certificate prices of €50 and €100, the comparable amounts would be €1.41 million and €2.83 million.
These are exposure scenarios, not estimates of an actual CBAM bill. They assume all production is covered and exported to the EU, exclude phase-in effects and other regulatory adjustments, and do not reflect the fact that the formal obligation belongs to the EU importer. The economic burden can still move upstream through lower purchase prices, carbon-cost clauses, warranties and demands for verified data.
More importantly, the direct-emissions sensitivity can be overtaken by the precursor. At €75 per tonne of CO₂, the difference between aluminium feedstock carrying an embedded-emissions value of 1.5 tonnes and feedstock carrying 6 tonnes is approximately €337.50 for every tonne of aluminium input. A producer unable to substantiate its supplier data may therefore face a commercial penalty several times larger than the value associated with its own furnaces.
This arrives at an uncomfortable point in Impol Seval’s operating cycle. The company recorded a €4.69 million net loss in 2025, compared with a marginal profit in 2024, while year-end capital declined to €67.23 million. Impol Group attributed the weaker result to difficult European market conditions, reduced capacity utilisation and margin pressure, compounded by a machine breakdown at Sevojno late in the year.
CBAM compliance is therefore not simply an environmental project. It is a margin-protection and working-capital exercise for a company already experiencing soft demand and high fixed-cost absorption. Purchasing teams will need to compare suppliers not only by metal premium, alloy and delivery schedule, but also by verified embedded emissions. Sales contracts will need to determine which party carries the financial risk when installation data are rejected or default values are imposed.
Impol has some useful foundations. The group has set a target to reduce emissions per tonne by 58 per cent by 2030, compared with 2021, and its rolling division is targeting at least 35 per cent secondary aluminium in the average charge. It also obtained Aluminium Stewardship Initiative Performance Standard and Chain of Custody certification in 2025. Those systems support traceability and responsible sourcing, although they do not replace CBAM-specific monitoring, reporting and third-party verification.

The immediate opportunity is to use Impol Seval’s recycling and casting capabilities to create product families with explicitly documented primary and secondary content. Scrap itself carries zero embedded emissions under the Commission methodology. The company must still disclose the volume of scrap consumed per tonne of product, distinguish pre-consumer scrap and report alloying elements exceeding 1 per cent. A credible low-carbon product claim will consequently require mass-balance discipline at batch, furnace and product level, rather than a general statement that the plant recycles aluminium.
Alumil YU Industry in Nova Pazova faces a different calculation. The Serbian subsidiary of Greece’s Alumil Group operates a 35,000-square-metre integrated facility with two extrusion lines, powder coating and thermal-break production. Publicly reported annual capacity is approximately 14,000 tonnes, and the business employs more than 400 people. It serves both the Serbian market and customers elsewhere in Europe. eKapija
For Alumil, extrusion and heat-treatment fuels generate the principal direct emissions included at the Serbian installation. Electricity for presses, handling equipment and other operations remains relevant to the full product footprint, customer procurement policies and corporate sustainability reporting, but it does not enter the aluminium CBAM embedded-emissions figure under Guidance 5E.
The larger question is billet provenance. Alumil has said that recycled aluminium used in its profiles is processed within the group’s industrial system in Kilkis, Greece. An integrated EU supply chain could become a competitive advantage if the company can link individual Serbian production batches to adequately documented EU-origin or low-carbon precursor material. Guidance 5E allows the origin of EU or exempt-territory precursor goods to affect their treatment, but the evidence must survive verification. Group ownership and internal invoices alone will not be enough.
Alumil YU obtained a new integrated environmental permit in February 2025 covering aluminium-profile production and surface treatment. The permit addresses energy efficiency, wastewater reuse, hazardous waste and the application of best available techniques. This creates a strong regulatory platform, although CBAM introduces a more granular data problem: the installation must align fuel consumption, production volumes, scrap flows and precursor declarations with the specific products being exported.

MTC NISSAL in Niš presents the most complex organisational case. MTC acquired NISSAL’s profile-extrusion operations in 2020 and subsequently took over the wider industrial capacity, including its foundry, drawing mill, bar production, machining and surface-treatment facilities. The operation includes a 1,500-tonne-force extrusion press and a larger 3,000-tonne-force press, while employment stood at approximately 269 people in 2023. MTC NISSAL
Vertical integration gives MTC NISSAL more control over metal preparation and conversion, but it also expands the CBAM boundary decisions it must document. The company may operate secondary melting, billet or bar production, extrusion, machining, anodising and powder coating within one industrial site. Each route has a different emissions logic.
The Commission permits a joint production process where an intermediate precursor remains inside the combined process. If billets or other intermediate goods are sold or transferred outside it, separate accounting may be required. MTC NISSAL must therefore map physical production flows against commercial transfers and legal entities, determining where unwrought aluminium becomes a precursor and where embedded emissions must be carried forward.
Its foundry could become an asset if it supports controlled use of scrap and verified secondary aluminium. But secondary content cannot be asserted through procurement totals alone. The company needs evidence covering scrap quantities, scrap classification, primary additions, alloys, production losses and fuel consumption for each reporting period. If primary and secondary routes are mixed without reliable records, the resulting uncertainty may push customers towards conservative values.
Across the three companies, the investment required is manageable relative to industrial plant expenditure but material relative to current margins. A working estimate by Clarion Engineering places initial CBAM readiness costs for a mid-sized Serbian aluminium installation at roughly €300,000–€800,000, with recurring annual expenditure of €150,000–€400,000. The range covers process metering, data architecture, ERP integration, laboratory and mass-balance controls, supplier assurance, verification and specialised personnel. It excludes major furnace replacement or broader decarbonisation projects.
An extrusion operation with a more concentrated product range could fall nearer €150,000–€450,000 initially, while an integrated foundry and extrusion complex may require €250,000–€700,000. These are analytical estimates rather than company-disclosed budgets. The decisive factor is not plant size alone but the number of alloys, suppliers, production routes and data handovers that must be verified.
Banks and trade-finance providers will increasingly encounter the consequences indirectly. An EU customer that cannot rely on a Serbian exporter’s emissions declaration may price its order using a higher default factor, retain part of the payment or require a contractual indemnity. A theoretical precursor difference worth €300–€600 per tonne can overwhelm the operating margin on a standard rolled or extruded product. Carbon-data quality thus becomes relevant to receivables, liquidity and covenant resilience even where the Serbian manufacturer is not the party purchasing CBAM certificates.
The Commission’s direct-emissions rule has spared Serbia’s aluminium sector from the most immediate impact of its carbon-intensive grid. It has not removed the need to decarbonise electricity: European customers will continue to measure full product footprints, while sustainability standards and corporate procurement rules often include Scope 2 emissions. The rule has simply separated two markets—the legally prescribed CBAM value and the broader commercial carbon footprint.
For Impol Seval, competitive advantage will come from connecting recycled content and low-carbon input purchases to individual rolled products. For Alumil YU, it will depend on turning an integrated Greek-Serbian supply chain into verifiable precursor evidence. For MTC NISSAL, it requires separating the emissions logic of foundry, extrusion and finishing operations without losing the benefits of vertical integration.
Serbia’s aluminium producers have avoided a calculation dominated by the national electricity mix. They now face a more exacting industrial test: proving, tonne by tonne, what metal entered the plant, how it was produced and how reliably that history follows the finished product across the EU border.
