As the Carbon Border Adjustment Mechanism (CBAM) creates a financial consequence for embedded emissions at the EU border, regulatory attention is shifting beyond declaration accuracy towards potential circumvention. The ongoing strengthening debate includes measures targeting country-product combinations and practices considered at high risk of undermining the intended carbon adjustment. This could make supply-chain risk classification increasingly important alongside individual declarations.
The existing regulation already empowers the European Commission and Member States to monitor circumvention and non-compliance. The pending strengthening package proposes additional mechanisms, including more systematic use of default treatment or other controls in high-risk situations. However, the positions adopted by Parliament and the Council differ in detail, leaving the final anti-circumvention framework subject to negotiation.
For businesses, the distinction between current law and proposed reform remains essential. The Commission proposal and the institutional negotiating positions can inform risk assessments, scenario planning and contract preparation, but they should not be treated as binding requirements for 2026 imports before the relevant amending legislation takes effect.
A two-scenario model—current law and potential reform—allows companies to prepare controls without basing existing declarations on measures that have not yet been adopted.
Country-Product Combinations Become a Risk Factor
For traders and importers, a formally complete data file may not be sufficient to resolve every compliance concern if the underlying trade pattern appears designed to avoid CBAM obligations. Sudden changes in declared origin, limited processing in an intermediate country, product modification or unusual emissions claims may attract scrutiny even when customs documents are internally consistent.
Companies should preserve evidence demonstrating the genuine commercial and production substance of their transactions. Relevant records include the location of physical processing, the reasons for sourcing changes, the identity of the installation producing the goods, the movement of precursor materials and the methodology used to calculate embedded emissions.
This documentation becomes particularly important when supply routes change after CBAM costs become financially significant. Businesses should be able to explain both the customs treatment and the operational reasons behind changes to suppliers, production locations or trading arrangements.
Customs and Carbon Controls Must Be Integrated
The CN code, origin, production country, inward-processing status and authorised-declarant identity can all affect the CBAM outcome before embedded emissions are calculated. Customs and carbon controls should therefore operate as an integrated compliance process.
A company that develops its monitoring, reporting and verification (MRV) procedures without customs input risks producing accurate emissions calculations for goods that have been incorrectly classified or treated at the border. Joint review by customs, procurement, production, MRV and finance teams is a substantive control rather than an administrative convenience.
The strongest preparation is modular. Systems should accommodate potential changes to product coverage, electricity rules and anti-circumvention requirements without requiring the entire compliance process to be rebuilt. Clear distinctions between binding legislation, official guidance and pending proposals also help prevent anticipated changes from being misrepresented as current obligations.
Commercial and Financial Consequences of Higher Risk
Anti-circumvention concerns can influence transaction pricing, supplier due diligence and financing decisions. Importers may apply additional scrutiny to suppliers or routes that could be challenged because a later change in classification or application of default values could increase CBAM certificate exposure.
Banks and insurers may also examine whether a business model depends on a regulatory interpretation that could be tightened. Companies should therefore assess not only the expected carbon cost but also the quality of the evidence supporting the proposed customs and emissions treatment.
Supplier onboarding and transaction approval procedures can incorporate circumvention-risk screening, particularly for new trading routes established after the definitive CBAM regime began in 2026. Such checks should focus on documented facts, including production locations, processing steps, precursor movements and the basis for origin claims.
Implications for Western Balkan Supply Chains
The Western Balkans occupy an important position between EU and non-EU industrial supply chains and can attract legitimate investment in processing and manufacturing. The compliance challenge is to distinguish genuine production activity from routing arrangements designed primarily to alter origin or emissions treatment.
Manufacturers undertaking real processing should be able to document the technical and economic substance of their operations. Production records, material flows, installation data and explanations of sourcing decisions can help demonstrate how goods were actually manufactured.
Exporters should not assume that ordinary supply-chain optimisation will automatically be treated as circumvention, nor should they assume that consistent paperwork alone resolves every risk. The relevant facts and applicable legal provisions need to be assessed together.
Evidence and Change Management
A robust compliance file should allow a company to explain its position to a verifier, customs authority, authorised declarant and commercial manager using consistent underlying records. It should connect purchasing, production, customs and finance, with controlled assumptions and documented alternatives where the preferred treatment cannot be substantiated.
The minimum decision record should identify the applicable legal status, customs treatment, responsible data owner, implementation deadline and approval process for key assumptions. It should also explain how the company will respond if a supplier, route, product classification or regulatory interpretation changes.
Defining an alternative treatment in advance can reduce the risk of discovering material exposure only when a claim is challenged. It also makes subsequent price adjustments, verification changes and management reporting easier to support with evidence.
For companies operating across several jurisdictions, policy monitoring should lead to specific actions. Each material regulatory development should be translated into changes to supplier checks, customs procedures, data requirements or contract terms, with a named owner and a deadline.
Enforcement Moves Beyond the Declaration
CBAM enforcement is increasingly concerned with the relationship between the declared information and the underlying trade and production activity. The existing framework already provides for monitoring circumvention, while the proposed strengthening measures could introduce additional controls once adopted.
Until the final legislation is settled, companies should distinguish existing obligations from potential future requirements. In the meantime, reliable customs records, traceable material flows and documented production substance provide a practical foundation for responding to scrutiny.
The central compliance question is no longer limited to whether the figures in a declaration are internally consistent. It also concerns whether the declared origin, production history, emissions calculation and commercial arrangements can be supported by the underlying evidence.
