The European Parliament’s latest move to widen the European Union’s Carbon Border Adjustment Mechanism could push CBAM far beyond Serbia’s steel, aluminium, cement, fertiliser and electricity sectors and into the country’s much larger manufacturing export base.
Parliament adopted its negotiating position on 15 September 2026 on a proposed expansion of CBAM to downstream goods containing significant volumes of steel and aluminium, alongside tighter anti-circumvention rules and changes affecting the treatment of electricity imports.
The measure is not yet final law. It must still be negotiated with the Council and European Commission.
But for Serbian manufacturers, the direction is increasingly clear: CBAM is evolving from a border charge concentrated on basic commodities into a supply-chain regime capable of following embedded carbon from steel mills and aluminium plants into machinery, electrical equipment, fabricated products and industrial components.
That shift could materially increase the number of Serbian companies whose access to the EU market depends on their ability to produce verifiable carbon data.
The European Commission initially proposed adding roughly 180 downstream product categories from 2028, while the Council has supported a list of around 200. Parliament has pushed for a much broader scope, covering about 457 product categories.
The final number will be determined in negotiations.
For Serbia, however, the difference between those positions is commercially significant. A narrower list would concentrate the next compliance wave mainly on selected metal-intensive products. A broader Parliament-style approach could pull sizeable parts of Serbia’s machinery, electrical equipment, construction-product and fabricated-metal industries directly into CBAM.
That matters because the EU remains Serbia’s dominant export market, accounting for around 58% of the country’s goods trade, while several of Serbia’s largest manufacturing export categories are precisely the sectors that could become exposed as CBAM moves downstream.
The next phase of the mechanism may therefore prove more disruptive to Serbia’s industrial economy than the original CBAM rollout.
CBAM moves from materials into manufactured products
CBAM’s initial definitive phase, which began on 1 January 2026, focuses on imports of cement, iron and steel, aluminium, fertilisers, electricity and hydrogen.
The downstream expansion changes the logic.
A Serbian company would no longer necessarily need to produce primary steel or aluminium to become relevant under CBAM. It could become exposed because the finished product it exports contains covered materials and falls under one of the CN customs codes ultimately included in the expanded regulation.
Potentially affected Serbian industries include fabricated metal products, machinery, industrial equipment, electrical equipment, metal construction components, fasteners, springs, wire products, heating and cooling equipment, household metal goods and certain automotive and industrial components.
For many of those companies, CBAM has so far been regarded largely as a supplier issue.
That distinction is likely to disappear.
A Serbian machinery manufacturer buying steel plate, machining it and exporting a finished component to Germany could itself become part of the CBAM reporting chain.
An electrical-equipment producer using aluminium profiles, sheet steel or fabricated enclosures could face the same problem.
The relevant compliance question would no longer be simply whether the factory emits significant amounts of carbon itself.
It would become whether the exporter can demonstrate the embedded emissions contained in the materials and processes incorporated into the product sold into the EU.
The importer remains responsible, but Serbia must produce the evidence
The legal responsibility under CBAM remains on the EU side.
The authorised CBAM declarant, usually the importer, is responsible for submitting the CBAM declaration and surrendering the required number of CBAM certificates.
But that importer cannot independently calculate the actual emissions of a Serbian plant.
The evidence has to originate with the producer.
The emerging operating chain is therefore increasingly clear:
Serbian installation → Serbian exporter → EU importer/declarant → accredited CBAM verifier → EU CBAM Registry.
That distinction between legal responsibility and evidence responsibility will become increasingly important in commercial negotiations.
The EU importer may carry the statutory obligation, but the Serbian producer or exporter controls much of the information needed to discharge it.
That means European buyers are likely to push CBAM requirements upstream through contracts.
Serbian exporters should expect procurement departments and importers increasingly to request installation identification, production data, embedded emissions, precursor information, electricity consumption, carbon-price information and verification documentation alongside ordinary commercial documentation.
In effect, CBAM data are likely to become part of the technical specification of an export product.
For exporters serving major EU industrial groups, that shift may occur before the expanded legislation formally takes effect.
Large buyers have little incentive to wait until the filing deadline before determining whether suppliers can produce compliant information.
Precursor traceability becomes the central issue
For downstream manufacturers, the most difficult part of CBAM may not be measuring emissions inside their own factory.
It may be tracing the carbon embedded in the steel and aluminium they buy.
Consider a Serbian producer of industrial equipment.
The factory may purchase steel plate from one supplier, aluminium components from another, wire from a third and cast parts from a fourth.
Under a downstream CBAM regime, those materials can become precursors whose embedded emissions must be reflected in the finished product.
The Serbian manufacturer may therefore need to establish:
- who produced the material;
- at which installation it was produced;
- which production route was used;
- how much embedded carbon it contains;
- whether that information has been verified;
- how much of the material entered the exported product;
- and how the resulting emissions were allocated to that product.
That represents a major shift in procurement.
Carbon information becomes part of supplier qualification.
Companies that currently buy metal primarily according to price, quality and delivery time may increasingly need to add CBAM data availability and verification status to purchasing criteria.
The effect could reach well beyond companies exporting directly to the EU.
A Serbian component producer supplying another Serbian manufacturer may also need to provide emissions information if the final product is subsequently exported into the European market.
CBAM therefore has the potential to propagate backwards through Serbia’s domestic industrial supply chain.
Two similar Serbian products could carry very different carbon costs
The ability to use verified actual emissions rather than less favourable default values could become an important competitive differentiator.
Two Serbian companies may produce broadly similar components and sell them at similar ex-works prices.
But if one can demonstrate that its product contains steel made through a lower-emission production route, uses verifiable low-carbon electricity and has a robust MRV system, while the other relies on incomplete data or default emissions, their effective cost to an EU buyer could diverge significantly.
This turns carbon accounting into a commercial variable.
The competitive proposition increasingly becomes:
product price + logistics + embedded carbon + quality of evidence.
For Serbian companies, that makes pre-verification increasingly valuable.
A pre-verification process can identify missing supplier data, inconsistent production allocation, weak meter hierarchies, incomplete electricity evidence or methodology problems before the accredited EU verifier examines the file.
The purpose is not to replace accredited verification.
It is to ensure that the exporter arrives at formal verification with an evidence chain capable of being verified.
The commercial risk of failing that test may ultimately be larger than the direct cost of verification itself.
An EU buyer confronted with incomplete carbon information may prefer a supplier whose data can be incorporated directly into its CBAM declaration.
Anti-circumvention rules raise the stakes for supply-chain documentation
Parliament is also pushing for stronger anti-circumvention powers.
The concern is that producers could attempt to avoid CBAM through minor product modifications, artificial processing steps, changes in customs classification, resource shuffling or routing through jurisdictions offering a more favourable apparent carbon profile.
The implications extend beyond deliberate avoidance.
Serbian exporters using imported steel or aluminium from third countries will increasingly need a defensible chain showing where the underlying material originated and how it was transformed in Serbia.
Customs origin and carbon origin are not necessarily the same thing.
A steel-intensive product may legitimately qualify as Serbian origin under customs rules after sufficient processing, while its carbon footprint still depends heavily on steel produced at an installation elsewhere.
CBAM therefore introduces a second layer of origin analysis.
Traditional customs compliance asks:
Where does the product legally originate?
CBAM increasingly asks:
Where did the emissions embedded in the product originate?
For companies sourcing metals from multiple jurisdictions, the distinction could become strategically important.
A Serbian certificate of origin will not by itself demonstrate the carbon intensity of an imported precursor.
Companies may consequently need stronger contractual rights to obtain installation-level information from suppliers outside Serbia as well as domestic ones.
Electricity becomes part of Serbian industrial competitiveness
The proposed reform also contains potentially important changes to the treatment of electricity under CBAM.
The Commission has proposed easing some conditions for the use of actual emissions for imported electricity, including allowing contractual structures involving intermediaries where a verifiable contractual chain exists.
At the same time, the underlying principle remains demanding: electricity claimed as qualifying supply must be connected to identifiable generation and physical market scheduling within tightly defined time intervals.
That could strengthen the commercial value of Serbia’s renewable electricity sector.
But Serbian exporters need to distinguish between two separate CBAM questions.
The first concerns electricity exported as a CBAM good into the EU.
In that case, the evidence chain links the renewable generator, contractual arrangement, cross-border schedule, EU importer/declarant and verifier.
The second concerns electricity consumed by a Serbian industrial installation producing other CBAM goods.
In that case, the relevant issue is whether electricity-related emissions can be treated in accordance with the methodology governing embedded emissions in the exported product.
The two systems interact but they are not interchangeable.
A Serbian factory buying a generic green electricity product or receiving a Guarantee of Origin should therefore not assume that the certificate automatically produces a zero-emission result for CBAM purposes.
The evidence supporting the electricity claim must still meet the methodology applicable to the exported good.
This creates a potentially important new market for structured renewable electricity products in Serbia.
Corporate PPAs, verifiable renewable supply, hourly metering, Guarantees of Origin and auditable energy-allocation systems could increasingly influence the carbon profile of Serbian manufactured exports.
For renewable producers, CBAM could therefore create value not only through direct electricity exports but also through supplying Serbian industrial companies seeking lower embedded emissions in goods sold into the EU.
Procurement departments become part of CBAM compliance
The next stage of CBAM will also change internal responsibility inside Serbian companies.
Until now, many businesses have treated CBAM primarily as an environmental, sustainability or finance issue.
Downstream expansion makes that approach increasingly inadequate.
Procurement determines the origin and characteristics of precursors.
Production determines material consumption and output allocation.
Energy teams determine electricity sourcing and metering.
Finance provides invoice and purchasing records.
Logistics provides import and export documentation.
Customs teams determine CN codes.
Legal departments negotiate data and liability clauses.
Management is ultimately responsible for ensuring that the chain works.
CBAM therefore becomes a cross-functional corporate process.
For many Serbian manufacturers, the practical architecture will resemble:
supplier qualification → precursor data → production records → energy data → product allocation → export documentation → importer evidence pack → verifier review.
A weak link anywhere in that chain can compromise the use of actual emissions.
EU buyers are likely to transfer compliance requirements upstream
The contractual consequences could be substantial.
EU buyers increasingly need assurance that their non-EU suppliers can provide the information required for the buyer’s CBAM obligations.
That is likely to produce a new generation of commercial clauses addressing:
CBAM data delivery, calculation methodologies, deadlines, verifier access, supplier cooperation, error correction, precursor information, evidence of carbon prices paid, audit rights and liability for inaccurate information.
For exporters, these clauses need careful review.
An apparently routine purchase contract could transfer substantial compliance obligations and financial exposure to the Serbian supplier.
For example, an importer may seek compensation if incorrect supplier data result in additional CBAM certificate costs, penalties or the need to use higher default values.
Serbian exporters should therefore avoid treating CBAM questionnaires from customers as informal ESG surveys.
They are increasingly becoming part of contractual risk allocation.
2027 becomes the decisive preparation year
The timing makes the issue particularly important.
The definitive CBAM regime began on 1 January 2026.
The first full annual CBAM declaration covering 2026 imports is due in 2027, together with the first major cycle of certificate surrender and verification.
The downstream expansion is targeted for 2028.
That effectively makes 2027 the preparation year for Serbia’s second wave of CBAM exposure.
Companies should use that period to establish whether they are likely to fall inside the expanded product scope and whether their supply-chain data can support verified actual emissions.
The logical sequence is:
CN-code screening → scope assessment → precursor mapping → installation-level MRV → electricity assessment → supplier-data collection → EU importer/declarant mapping → evidence-pack preparation → pre-verification → accredited verification readiness.
The first step is particularly important.
Companies should not assess CBAM exposure solely according to broad industry descriptions.
CBAM applies through specific customs classifications.
A machinery producer may export several product lines, only some of which eventually fall within the expanded mechanism.
The final negotiated CN-code list will therefore determine the precise Serbian exposure.
The impact could spread through Serbia’s industrial export model
The broader strategic question is how Serbian manufacturing competes inside European supply chains once carbon becomes another measurable attribute of imported products.
Serbia has built a substantial part of its export economy around integration with EU manufacturing.
European companies buy Serbian electrical equipment, machinery, metal products, automotive components and intermediate goods partly because Serbia combines industrial capacity, proximity to the EU and competitive production costs.
CBAM adds another variable.
Serbian factories with carbon-intensive energy, poorly documented precursor supply and weak emissions data could become more expensive or administratively difficult for EU customers.
Factories with lower-carbon inputs, reliable renewable electricity and verifier-ready documentation could gain an advantage.
That does not necessarily mean European buyers will abandon higher-emission suppliers.
Price, quality, logistics, capacity and technological capability will remain critical.
But carbon becomes another factor in supplier selection.
For companies operating on thin manufacturing margins, even relatively small differences in CBAM exposure could influence sourcing decisions.
Serbia faces a wider CBAM challenge than originally expected
The original CBAM debate in Serbia largely centred on steel, aluminium, cement, fertilisers and electricity.
That framing is rapidly becoming outdated.
If the downstream expansion survives negotiations in anything close to Parliament’s broader position, CBAM will move into the heart of Serbia’s export manufacturing economy.
The critical exposure will no longer stop at the steel mill or aluminium producer.
It will extend to companies cutting, machining, welding, assembling and transforming those materials into products sold across the EU.
The statutory liability may remain with the EU declarant, but the evidence chain increasingly begins inside Serbia.
For exporters, the commercial question is therefore becoming more demanding than simply determining whether CBAM applies.
It is whether an EU customer can take the data generated in a Serbian factory, trace the carbon embedded in its materials and electricity, submit it through the CBAM system and have it accepted by an accredited verifier.
Companies able to provide that chain should enter the next phase of CBAM with a stronger negotiating position.
Those that cannot may discover that the real border adjustment is not simply the price of carbon, but the cost of being unable to prove what is inside the product.
