BRUSSELS, Oct. 22, 2026 – European importers of carbon-intensive products face a potential cash-flow squeeze as costs under the definitive Carbon Border Adjustment Mechanism (CBAM) emerge after goods have already entered the market and may have been resold. Imports made in 2026 generate certificate obligations that will be funded through purchases beginning in 2027, requiring businesses to estimate and finance liabilities that may not yet be reflected in supplier invoices.
CBAM covers selected steel, aluminium, cement, fertiliser, electricity and hydrogen products. EU importers and qualifying indirect customs representatives exceeding the annual 50-tonne mass-based threshold for relevant goods generally need authorised CBAM declarant status. Electricity is treated differently, with quantities measured in megawatt-hours rather than tonnes. Businesses must assess their individual import flows under the consolidated regulation rather than interpret the threshold as a universal exemption.
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 2026, the European Commission sets quarterly certificate prices based on average EU Emissions Trading System (EU ETS) auction prices. The published rates are €75.36/tCO₂e for Q1, €75.28 for Q2 and €82.32 for Q3.
The financing gap begins when goods clear customs
A company’s economic exposure starts when covered goods are released for free circulation, even though the certificate-surrender deadline falls later. Importers may pay suppliers and sell their inventory before receiving the final emissions-verification documentation.
If a manufacturer cannot provide acceptable emissions data, the importer may have to use the applicable regulated default values, including prescribed markups for many products. Procurement teams comparing suppliers solely on invoice prices can therefore underestimate the full landed cost.
Consider an illustrative shipment of 10,000 tonnes with net chargeable emissions of 0.6 tCO₂e per tonne, after all relevant methodological calculations and adjustments. At a certificate price of €82.32, the modelled exposure would be €493,920. If a second valid calculation established emissions of 0.2 tCO₂e per tonne, the corresponding exposure would be €164,640.
These figures are stress-test assumptions, not official default values for any particular product. The resulting €329,280 difference illustrates the financial significance of obtaining verified factory-level emissions data.
Importers can manage this exposure through credit facilities, contractual cost pass-through clauses, pricing reserves and stronger verification rights. However, EUA futures are not CBAM certificates, and their prices do not necessarily match the quarterly rate subsequently assigned to 2026 imports. Loan agreements should specify how outstanding carbon provisions affect borrowing-base availability and covenant calculations.
Verification rights become a commercial and financial safeguard
Effective supply contracts should identify the manufacturing installation, relevant product code, reporting period, production route, precursor inputs and responsible verifier. They should also establish access to underlying metering and production records, procedures for correcting errors and remedies when 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 the 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 the assurance required for the use of actual emissions where applicable.
Connecting registry references with customs records and commercial invoices helps prevent shipments from being counted twice or assigned to the wrong installation.
Customs values alone cannot determine carbon liabilities
Import values and carbon exposure are fundamentally different measures. An import of €1 million in steel, for example, does not by itself establish the quantity, grade, production route or emissions liability of the goods.
The calculation must begin with the relevant Combined Nomenclature (CN) classification and net mass, followed by the applicable emissions methodology and adjustment factors. Importers using a fixed percentage of customs value as a CBAM cost estimate risk underpricing high-emission goods while overestimating liabilities for lower-emission supplies.
Financial planning must address two separate uncertainties: the final number of certificates required and the cash needed to acquire them.
Some companies may know their imported tonnage precisely but lack plant-level verification until months after year-end. Others may have reliable emissions data but experience a concentration of purchases late in the year. Monthly accruals, supplier-specific exposure limits and regular reconciliation of customs records can provide better control than creating a single carbon reserve when the first shipment arrives.
Clear ownership of controls can prevent costly disputes
The administrative process should assign responsibility for each control. Customs specialists validate product classifications and origin; procurement verifies the factory and product; 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 involved, the commercial agreement must establish which information the importer supplies and whether the representative has the necessary capacity and authority to fulfil the relevant duties.
Disputes can generate substantial costs even when the imported goods themselves comply with applicable product requirements.
Verified emissions data could strengthen Western Balkan exporters
For manufacturers in Serbia and Montenegro, the gap between customs clearance and final certificate settlement creates a potential commercial opportunity. Exporters that provide reliable, verified emissions information early may help EU buyers improve working-capital planning and reduce the need for price holdbacks.
The first certificate sales in February 2027 will test not only European importers’ carbon budgets but also the quality of emissions evidence, verification arrangements and payment clauses negotiated throughout 2026.
