European importers of carbon-intensive products may face a cash-flow squeeze under the definitive Carbon Border Adjustment Mechanism (CBAM), as certificate-related costs can arise after goods have entered the market and may have been resold. Imports recorded in 2026 create certificate obligations that are funded through purchases starting in 2027. Businesses therefore need to estimate and finance liabilities that may not yet appear in supplier invoices.
CBAM applies to selected steel, aluminium, cement, fertiliser, electricity and hydrogen products. EU importers and qualifying indirect customs representatives that exceed an annual threshold of 50 tonnes for relevant goods generally need authorised CBAM declarant status. Electricity is measured in megawatt-hours rather than tonnes, and companies are required to assess their specific import flows under the consolidated regulation rather than treat the threshold as a blanket exemption.
Certificate sales schedule and 2026 declaration timing
Certificate sales through the common central platform are scheduled to begin in February 2027. The first CBAM declaration and certificate surrender deadline is Sept. 30, 2027, covering emissions attributable to goods imported during 2026. This timing means obligations linked to 2026 imports are settled later than the point at which covered goods enter the EU market.
For 2026, the European Commission sets quarterly certificate prices based on average EU Emissions Trading System auction prices. The published rates are €75.36/tCO₂e for Q1, €75.28 for Q2 and €82.32 for Q3. These quarterly figures determine the cost basis for certificates surrendered for emissions attributable to that period.
Exposure starts at release for free circulation
The financing gap begins when covered goods clear customs, even though the certificate surrender deadline occurs later. A company’s economic exposure starts when goods are released for free circulation, not when final emissions verification documentation becomes available. Importers may pay suppliers and sell inventory before they receive the final documentation needed for the declaration.
If a manufacturer cannot provide acceptable emissions data, the importer may need to apply regulated default values, including prescribed markups for many products. Procurement teams that compare suppliers only on invoice prices can therefore underestimate total landed cost under CBAM. The approach to estimating costs depends on whether actual emissions data can be supplied in time for reporting.
Illustrative exposure differences using quarterly pricing
An illustrative shipment of 10,000 tonnes with net chargeable emissions of 0.6 tCO₂e per tonne, after methodological calculations and adjustments, results in exposure of €493,920 at a certificate price of €82.32. A second valid calculation establishing emissions of 0.2 tCO₂e per tonne produces exposure of €164,640. The difference between these stress-test scenarios is €329,280.
The figures are described as stress-test assumptions rather than official default values for any specific product. Importers can manage exposure through credit facilities, contractual cost pass-through clauses, pricing reserves and stronger verification rights. The text also notes that EUA futures are not CBAM certificates and their prices do not necessarily match the quarterly rate assigned to 2026 imports.
Loan agreements should specify how outstanding carbon provisions affect borrowing-base availability and covenant calculations. This requirement links CBAM-related provisions to broader financing terms during periods when certificates have not yet been purchased or surrendered.
Contract terms and registry-based verification support
Supply contracts are expected to identify the manufacturing installation, relevant product code, reporting period, production route, precursor inputs and the responsible verifier. Contracts should also cover access to underlying metering and production records, procedures for correcting errors and remedies if supporting data arrive too late for the required declaration.
The authorised importer remains accountable for its CBAM declaration even when a supplier or consultant prepares supporting documentation. The CBAM Registry supports declarant authorisation, installation emissions data and relevant operator functions. Operators of installations outside the EU can contribute emissions information, while independent accredited verifiers provide assurance where actual emissions are used.
The text states that connecting registry references with customs records and commercial invoices helps prevent shipments from being counted twice or assigned to the wrong installation. It also distinguishes between customs values and carbon liabilities by noting that customs value alone cannot determine carbon exposure.
Customs value does not determine carbon liability
An import value does not by itself establish quantity, grade, production route or emissions liability under CBAM. The calculation must start with the relevant Combined Nomenclature classification and net mass, followed by applicable emissions methodology and adjustment factors. Using a fixed percentage of customs value as a CBAM cost estimate can risk underpricing high-emission goods while overestimating liabilities for lower-emission supplies.
The planning process must address two uncertainties: the final number of certificates required and the cash needed to acquire them. Some companies know imported tonnage precisely but lack plant-level verification until months after year-end, while others have reliable emissions data but concentrate purchases late in the year.
The text highlights monthly accruals, supplier-specific exposure limits and regular reconciliation of customs records as controls that may be preferable to creating a single carbon reserve when early shipments occur.
Allocation of compliance responsibilities and dispute risk
The administrative process should assign responsibility for each control across functions including customs classification checks, procurement verification of factory and product details, engineering review of emissions models, compliance coordination of verification activities, and finance management of provisions and certificate purchases. The authorised declarant remains responsible for filing an accurate declaration regardless of who prepares supporting documentation.
If an indirect customs representative is used, commercial agreements must define which information the importer supplies and whether the representative has capacity and authority to perform relevant duties. Disputes can generate substantial costs even when imported goods comply with applicable product requirements.
Potential implications for Serbia and Montenegro exporters
The text identifies manufacturers in Serbia and Montenegro as facing a gap between customs clearance and final certificate settlement that could create a commercial opportunity. Exporters providing reliable verified emissions information early may help EU buyers improve working-capital planning and reduce reliance on price holdbacks.
The first certificate sales in February 2027 are described as testing not only European importers’ carbon budgets but also the quality of emissions evidence, verification arrangements and payment clauses negotiated throughout 2026.
