The European Union’s Carbon Border Adjustment Mechanism (CBAM) was conceived as a climate policy tool designed to prevent carbon leakage and level the playing field between European industry and foreign competitors. Yet long before the mechanism begins to impose financial carbon costs on imports, it is already reshaping commercial behaviour across European supply chains.
Procurement departments inside European industrial companies are becoming noticeably more cautious when sourcing goods from outside the EU. For exporters in Serbia, whose steel, aluminium, fertilisers and other industrial materials are closely tied to EU markets, this shift is beginning to influence contracts, pricing discussions and supplier relationships.
CBAM’s transitional phase, which runs from October 2023 until the end of 2025, requires importers to report the embedded carbon emissions of goods entering the EU. The financial component of the mechanism will begin gradually from 2026, when importers will have to purchase CBAM certificates reflecting the carbon intensity of the imported products.
Despite the absence of immediate carbon payments during the transitional phase, many EU importers are already adjusting their sourcing strategies. The reason lies in the structure of CBAM itself: the legal and financial responsibility for reporting emissions falls primarily on the importer, not the exporter.
That structural feature has turned carbon data into a new category of supplier risk.
Carbon data is becoming a procurement requirement
Under CBAM, importers must submit detailed quarterly reports covering the carbon emissions embedded in imported goods. These reports must include direct emissions from industrial production as well as indirect emissions associated with electricity consumption.
If accurate emissions data cannot be obtained from a supplier, importers must rely on default values, which are typically higher than real emissions. This effectively inflates the future carbon cost attached to a shipment.
In sectors where margins are already thin, such as steel and aluminium trading, the difference between verified emissions data and default carbon intensity values can materially affect profitability.
As a result, many European buyers are introducing new supplier screening criteria. Procurement teams are increasingly requesting detailed information on production emissions, electricity sourcing, and carbon reporting systems before entering into long-term supply agreements.
The shift resembles a quiet transformation in procurement practice. Carbon reporting is gradually becoming a standard element of supplier evaluation, similar to quality assurance or financial stability assessments.
For exporters outside the EU, this development is creating a new layer of commercial scrutiny.
Serbian exporters enter the carbon transparency era
Serbia’s industrial export sector is deeply integrated into European manufacturing value chains. The EU remains the country’s largest trading partner, absorbing a substantial share of Serbian exports in metals, construction materials and industrial inputs.
These sectors are also among the first to be covered by CBAM.
For Serbian producers, the mechanism introduces a new requirement: the ability to document the carbon intensity of production processes with a level of precision that many companies have never previously needed to provide to foreign customers.
The challenge lies not only in calculating emissions but in establishing systems capable of measuring and verifying those emissions according to EU methodologies.
Industrial producers must now gather data across multiple parts of the production process. This includes fuel use in furnaces, electricity consumption across manufacturing stages, and in some cases the emissions embedded in upstream raw materials.
European buyers increasingly expect this information to be organised into clear reporting frameworks.
Companies unable to provide such data risk appearing uncertain or non-compliant from the perspective of EU importers.
Electricity mix becomes a hidden factor
One of the less visible complications for Serbian exporters arises from the structure of the country’s power system.
CBAM calculations include emissions linked to electricity consumption during manufacturing. Because Serbia’s electricity generation mix still contains a large share of lignite-based power, the indirect emissions associated with electricity use can significantly increase the carbon intensity of exported goods.
This dynamic creates a paradox for industrial exporters.
A factory may operate with relatively efficient production technology, yet the emissions associated with the electricity powering that facility can still increase the overall carbon footprint of the product under CBAM calculations.
European importers are increasingly aware of this distinction.
When assessing suppliers, they are beginning to examine not only the efficiency of production processes but also the energy systems powering those processes. Countries with carbon-intensive electricity systems may therefore appear riskier from a CBAM compliance perspective.
Financial uncertainty encourages conservative purchasing
Another factor driving importer caution is the uncertainty surrounding future carbon prices.
Once CBAM becomes fully operational, importers will need to purchase certificates linked to the price of allowances under the EU Emissions Trading System (ETS). Carbon prices in the EU ETS have fluctuated widely in recent years, often trading in the range of €70–€100 per tonne of CO₂.
For buyers, this creates uncertainty in forecasting the final landed cost of imported goods.
If emissions data from suppliers is incomplete or unreliable, the importer cannot accurately estimate the number of CBAM certificates required for each shipment. This uncertainty encourages conservative procurement strategies.
European companies increasingly prefer suppliers who can demonstrate reliable emissions reporting and clear decarbonisation strategies. Such suppliers reduce the regulatory and financial risk faced by importers.
This trend is gradually reshaping the hierarchy of suppliers in European industrial procurement systems.
A procurement filter emerging before carbon costs arrive
Although CBAM’s financial impact will only begin after 2026, its influence on procurement decisions is already becoming visible.
Importers are effectively introducing a new screening mechanism into supply chains. Suppliers with credible carbon reporting systems are treated as lower-risk partners, while those with unclear emissions data may face closer scrutiny.
The adjustment rarely takes the form of sudden contract cancellations. Instead, it unfolds gradually through procurement reviews, contract renegotiations and supplier audits.
In some cases, buyers may request additional documentation before finalising new supply agreements. In others, they may incorporate carbon-related clauses into contracts or adjust pricing to account for potential CBAM costs.
For exporters unfamiliar with these dynamics, the process can appear confusing. The regulatory obligations remain formally limited to reporting, yet the commercial implications are already affecting market behaviour.
The risk of over-caution
Some analysts argue that the caution emerging among importers may currently exceed the immediate regulatory risk.
During the transitional phase of CBAM, importers are only required to report emissions data. They do not yet have to pay the carbon charges associated with those emissions.
This means exporters technically still have time to develop emissions monitoring systems and reporting processes before the financial component of CBAM takes effect.
However, large industrial buyers rarely wait for full regulatory clarity before adjusting procurement strategies. The potential reputational and compliance risks associated with inaccurate reporting encourage companies to prepare early.
In this sense, the behaviour of importers reflects a typical corporate response to regulatory uncertainty.
Companies prefer to secure supply chains that appear compliant in advance rather than face last-minute adjustments once financial penalties begin to apply.
A strategic window for Serbian industry
For Serbian exporters, the emerging dynamics around CBAM represent both a challenge and an opportunity.
Companies capable of building robust emissions reporting systems may strengthen their position within European supply chains. Importers increasingly value suppliers who can provide transparent carbon data and demonstrate credible pathways toward lower-emissions production.
The ability to supply verified emissions information, energy-mix disclosures and decarbonisation strategies may soon become as important as price competitiveness.
In this environment, exporters who move early to align with CBAM reporting requirements may gain an advantage over competitors who delay adaptation.
European procurement systems are gradually incorporating carbon transparency into supplier evaluation frameworks.
A quiet transformation of trade
The early effects of CBAM illustrate a broader transformation taking place within European trade.
Climate regulation is beginning to influence supply chains not only through direct carbon pricing but through the behaviour of companies operating within those supply chains.
Importers are acting as de facto compliance gatekeepers, demanding more information from suppliers and integrating carbon considerations into procurement strategies.
For Serbian exporters whose industrial sectors remain deeply connected to EU markets, this shift marks the beginning of a new phase in trade relations.
Carbon reporting, once a niche environmental issue, is becoming an operational requirement in cross-border commerce.
As CBAM moves toward full implementation later in the decade, the companies that adapt earliest to this new transparency regime are likely to find themselves in a stronger position within Europe’s evolving industrial marketplace.
