Long-term steel supply agreements between European buyers and non-EU producers are being updated as CBAM introduces carbon-related costs that may not be known at the time a shipment is delivered. The final economic value of imported steel increasingly depends on verified embedded emissions, the applicable EU ETS-linked certificate price, and adjustments tied to the phase-out of free allocation.
Under the mechanism, importers can face financial obligations determined months after physical delivery. This can occur when emissions verification or the final certificate requirement is established later, shifting when contractual carbon liabilities are quantified. As a result, contracts are placing greater emphasis on how responsibilities for emissions documentation are allocated and how price adjustments are handled.
Embedded emissions data and allocation of supplier responsibilities
A central contractual issue concerns which party provides information needed to calculate embedded emissions. While the EU importer remains responsible for the CBAM declaration, the producing installation holds operational records used to determine the carbon intensity of its products.
Supply agreements are expected to specify the manufacturing installation, production route, applicable reporting methodology, expected verification status, and documentation requirements for relevant precursor materials. Contracts also need deadlines for submitting emissions information and procedures for correcting inaccurate or delayed declarations after customs clearance.
Without clearly assigned responsibilities, importers may face compliance exposure linked to information controlled by overseas producers. This includes situations where emissions data is held outside the EU and becomes available only after delivery or after verification steps.
Emissions performance warranties and treatment of verified deviations
Emissions performance warranties are another contractual element in steel transactions. An exporter may offer steel produced through a lower-emissions route, but buyers require calculations that follow the applicable CBAM methodology.
If verified embedded emissions exceed the level guaranteed when the purchase agreement was concluded, contracts need to define how the additional carbon obligation is allocated. Possible approaches include supplier compensation, shared liability, or renegotiation of the purchase price.
Warranty boundaries also require clarity because general statements about carbon neutrality do not necessarily establish an emissions figure relevant to the payable CBAM calculation. Contracts therefore need to connect any guarantee to the specific emissions basis used for CBAM purposes.
Indexing CBAM certificate prices in long-term contracts
Carbon-price movements are creating additional dispute points between steel suppliers and European importers. For 2026 imports, the EU applies a published quarterly CBAM certificate price, while weekly pricing applies from 2027.
Contracts can link the carbon component of transactions to these official reference periods rather than relying on an unrelated EU Allowance (EUA) futures quotation. This is intended to align contractual carbon pricing with the periods used in CBAM compliance.
Agreements are also expected to separate transaction elements by identifying base steel price, transportation charges, customs duties, and carbon-related payments independently. This structure supports reconciliation between commercial invoices and eventual CBAM compliance costs.
Data access rules for verification and confidentiality
Access to emissions documentation can create tensions between regulatory requirements and protection of commercially sensitive manufacturing information. European buyers may need evidence suitable for examination by an accredited verifier or competent authority.
This does not automatically justify unrestricted access to a steel mill’s production formulas, customer information, or cost structure. Contracts can address this through controlled data-sharing arrangements such as secure data rooms, authorised recipients, defined information-retention periods, and protected transfer procedures.
Where intermediary traders buy from a mill and resell to an EU importer, emissions warranties and documentation obligations need to remain enforceable across the transaction chain. Back-to-back contractual guarantees can support that information promised by an intermediary is backed by commitments from the actual producing installation.
Dispute procedures are also part of contract design where disagreements arise over emissions allocation or reporting inconsistencies. A defined correction mechanism and access to an independent technical expert can be used as a framework without treating every discrepancy as a conventional product-quality claim.
Regulatory change provisions affecting multi-year deliveries
The evolving EU regulatory framework adds uncertainty for contracts covering several years of steel deliveries. The European Commission has proposed changes to the EU ETS free-allocation phase-out schedule and an extension of CBAM to selected downstream products.
These items remain proposals and should not be treated as adopted legislative requirements when calculating existing contractual obligations. Long-term agreements therefore need provisions addressing potential changes to covered product categories, emissions benchmark methodologies, and timetables for withdrawing free allocation.
Contracts should distinguish ordinary market price movements from additional costs resulting from regulatory amendments. Clearly defined adjustment mechanisms are intended to prevent either party from reopening the entire steel price without an objective contractual basis.
Financing and credit risk tied to certificate obligations
Financial arrangements also need to reflect liabilities created by emissions warranties and certificate obligations. Steel exporters may be required to provide bank guarantees covering commitments related to emissions data.
Importers may need financing for CBAM certificates purchased in 2027 in respect of 2026 transactions. Credit departments are therefore expected to monitor contingent carbon-related claims alongside conventional trade receivables and payment obligations.
Where intermediary traders operate between overseas mills and European buyers, financing arrangements must preserve the contractual chain of emissions evidence and liability. Successive transfers of ownership should not interrupt access to required information or enforcement of warranties needed for CBAM compliance.
In international steel transactions, contractual certainty increasingly depends on clearly identified emissions inputs, recognised carbon-price references, allocated responsibilities, and procedures for correcting discrepancies. These provisions form the basis for determining final carbon-related costs across the supply chain for imported steel.
