European importers of carbon-intensive products face a potential cash-flow squeeze under the definitive Carbon Border Adjustment Mechanism (CBAM), because certificate-related costs can arise after goods have already entered the market and may have been resold. Imports made 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 50-tonne mass-based threshold for relevant goods generally need authorised CBAM declarant status. Electricity is handled differently, with quantities measured in megawatt-hours rather than tonnes. 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 price setting
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. For the 2026 period, the European Commission sets quarterly certificate prices based on average EU Emissions Trading System auction prices.
The published rates for 2026 are €75.36/tCO2e for Q1, €75.28 for Q2, and €82.32 for Q3. These quarterly prices are linked to average EU ETS auction outcomes used for the CBAM pricing mechanism.
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. Importers may pay suppliers and sell inventory before receiving final emissions-verification documentation needed for CBAM reporting.
If a manufacturer cannot provide acceptable emissions data, the importer may have 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.
An illustrative shipment of 10,000 tonnes with net chargeable emissions of 0.6 tCO2e per tonne would create exposure of €493,920 at a certificate price of €82.32. A second valid calculation showing emissions of 0.2 tCO2e per tonne would correspond to exposure of €164,640. The difference between the two modelled exposures is €329,280.
The figures are stress-test assumptions rather than official default values for any specific product. Importers can manage exposure using credit facilities, contractual cost pass-through clauses, pricing reserves and stronger verification rights. The source also notes that EUA futures are not CBAM certificates and do not necessarily track the quarterly rate assigned to 2026 imports.
Contract terms and verification documentation
Supply contracts are expected to specify key elements including the manufacturing installation, relevant product code, reporting period, production route and precursor inputs. Contracts should also name the responsible verifier and set out access to underlying metering and production records. They should include procedures for correcting errors and remedies when supporting data arrive too late for required declarations.
The authorised importer remains accountable for its CBAM declaration even if a supplier or consultant prepares supporting documentation. The CBAM Registry supports declarant authorisation as well as installation emissions data and relevant operator functions. Operators of installations outside the EU can contribute emissions information, while independent accredited verifiers provide assurance needed where actual emissions are used.
The source also highlights that linking registry references with customs records and commercial invoices can help prevent shipments from being counted twice or assigned to the wrong installation.
Customs value versus carbon liability calculations
Import values and carbon exposure are treated as different measures under CBAM calculations. An import value—for example, €1 million in steel—does not by itself determine quantity, grade, production route or emissions liability of the goods.
The calculation must start with the relevant Combined Nomenclature (CN) classification and net mass, followed by the applicable emissions methodology and adjustment factors. Using a fixed percentage of customs value as a CBAM cost estimate is described as creating risk of underpricing high-emission goods while overestimating liabilities for lower-emission supplies.
Financial planning needs to 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 face purchase concentration late in the year.
The source states that monthly accruals, supplier-specific exposure limits and regular reconciliation of customs records can provide better control than creating a single carbon reserve when an initial shipment arrives.
Allocation of compliance responsibilities
The administrative process should assign responsibility for each control activity across functions. Customs specialists validate product classifications and origin; procurement verifies factory and product details; engineers review the emissions model; compliance teams coordinate verification; and finance records provisions and manages certificate purchases.
The authorised declarant remains responsible for filing an accurate declaration. Where an indirect customs representative is used, commercial agreements should define which information the importer provides and whether the representative has capacity and authority to perform relevant duties.
The source notes that disputes can generate substantial costs even when imported goods meet applicable product requirements.
Verified emissions information for exporters in Serbia and Montenegro
A potential commercial opportunity is described for manufacturers in Serbia and Montenegro due to timing differences between customs clearance and final certificate settlement in EU markets. Exporters that provide 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 will test both European importers’ carbon budgets and aspects including quality of emissions evidence, verification arrangements and payment clauses negotiated throughout 2026.
