Companies importing CBAM-covered products into the European Union during 2026 will need to finance associated carbon liabilities in the following year. The timing difference between the import period and the certificate payment schedule creates a working-capital requirement. Businesses must account for this before their final emissions obligations are established.
CBAM certificates are available for purchase from February 2027. The first annual declaration and corresponding certificate surrender are due by 30 September 2027. Although the emissions relate to goods imported throughout 2026, the cash requirement arises later, which can occur after products have been sold or processed.
Working-capital timing between imports and certificate surrender
The funding timeline is particularly relevant for firms handling large volumes on narrow margins. A metals trader may buy thousands of tonnes under short payment terms and resell the material before its CBAM obligation is finalised. A cement importer may receive payment from a distributor while waiting for the producing plant to provide verified emissions information.
In both examples, the carbon expense remains linked to earlier imports even though certificate payment occurs in a later financial period. Importers are therefore expected to consider future liabilities when pricing transactions and planning liquidity. This approach differs from treating the cost as arising only at the annual compliance deadline.
How CBAM requirements are calculated for imported goods
The calculation involves more than applying an EUA price to imported tonnage. The final requirement depends on embedded emissions, adjustments tied to EU free allocation, and eligible deductions for carbon prices paid abroad. These variables can vary across products and installations, especially where an importer sources from multiple suppliers.
A transaction-level ledger is used to record each consignment, import quarter, relevant benchmark, calculation methodology, and verification status. This structure supports updating provisional carbon accruals as supplier evidence becomes available and as the expected certificate requirement changes.
Treasury scenario modelling for potential funding gaps
Treasury teams can estimate exposure using three emissions scenarios: verified actual emissions close to the applicable benchmark, a higher-emissions outcome, and a default-value scenario when sufficient evidence is unavailable. Each scenario can then be assessed against ETS-linked price ranges and the applicable CBAM calculation rules.
The resulting estimates indicate potential funding requirements and identify which missing supplier records drive uncertainty. A model that applies one carbon-cost percentage across an entire corporate group is unlikely to reflect differences between products, installations, and suppliers. Funding models need to capture those variations rather than rely on a single general estimate.
Monthly cash forecasts should incorporate expected certificate requirements ahead of the September 2027 deadline. A rolling approach can organise shipments by import quarter, supplier, estimated embedded emissions, and the quality of available verification evidence to produce low and high funding estimates.
Management can compare projected requirements with revolving credit availability and possible customer prepayments. The model also needs to reflect changes in expected liability, including potential shifts from pending plant verification and reductions from eligible foreign carbon-price deductions that lower the net amount due.
Trade-finance implications for banks and importers
The same shipment records can support lenders assessing importer liquidity. This is particularly relevant for fast-turnover traders where gross profit may be modest relative to the value and volume of imported metals.
Banks providing trade finance need to separate the customs value of goods from the separate cash outlay associated with CBAM certificates. Revolving facilities may require additional headroom to cover the timing gap between imports and certificate purchases.
Borrower covenants may also need adjustment based on when carbon expenses arise compared with when inventory is sold and when certificates must be purchased. Importers could respond by seeking carbon-cost deposits from customers or renegotiating payment terms with exporters that control access to production and emissions data.
Because delayed emissions documentation can affect both final certificate calculations and an importer’s ability to forecast funds, supplier information quality and timing become commercially significant. This includes how quickly verified emissions evidence is provided relative to compliance needs.
Verification, customs controls, and operational compliance
Funding arrangements require operational compliance procedures to support final exposure calculations. Buyers require authorised-declarant status where applicable, accurate customs classifications, access to the CBAM registry, and an established process for collecting installation-level emissions information.
Independent verification of actual emissions can take time and may include site visits and documentary reviews. If a supplier does not provide required evidence within the relevant timeframe, importers may need to plan around default values or other permitted fallback arrangements instead of assuming lower reported emissions will be accepted.
The quality of emissions records affects how reliably financial forecasts can be made. Companies are expected to track verification progress alongside shipment and payment information so unresolved data gaps are reflected in funding estimates.
The first annual declaration and surrender deadline on 30 September 2027 covers carbon exposure associated with imports made during 2026. By that point, importers will need to reconcile traded goods with verified emissions information and certificates required under the mechanism.
