The EU Carbon Border Adjustment Mechanism (CBAM) assigns responsibility for submitting a correct declaration to the authorised declarant, even when emissions evidence is generated at manufacturing facilities outside the importer’s control. The compliance approach requires reliable links between purchased goods, the producing installations and the verified emissions information used in reporting.
Supplier selection under CBAM therefore extends beyond purchase pricing. Importers need to identify where goods were manufactured, obtain emissions data suitable for CBAM reporting and reconcile those figures with customs records. Verification can support the reliability of factory emissions information, but the importer remains responsible for using the appropriate data in its declaration.
Who can submit CBAM declarations and how responsibilities are assigned
The authorised declarant can be the importer or an indirect customs representative that has accepted the role under applicable arrangements. The appointment of a customs broker to process entries does not automatically transfer CBAM responsibilities to that broker. Import contracts, representation agreements and internal procedures should identify the responsible legal entity before shipments arrive.
Importers also need to determine whether their goods fall within CBAM’s scope and whether an exemption applies. The annual mass threshold of 50 tonnes applies to the relevant goods, while electricity and hydrogen are excluded from that threshold exemption.
Timing for 2026 imports and verification requirements
For declarations based on actual emissions, regulatory requirements include verification by an appropriately accredited CBAM verifier. The first annual declaration covering 2026 imports is due on 30 September 2027. This timeline separates the period in which production data are generated from the following year’s annual compliance process.
The later submission deadline does not remove the need for complete factory records. Missing measurements or inadequate supplier documentation may be difficult to reconstruct after the relevant production period has ended. Importers therefore need access to complete emissions evidence covering the production period used for reporting.
Internal controls connecting procurement, customs and emissions data
A coordinated control system can align procurement, customs, sustainability and finance functions within a single reporting process. Procurement teams set emissions-data obligations with suppliers, while customs personnel maintain imported quantities and product classifications. This structure supports consistent inputs for CBAM declarations.
The carbon or sustainability team checks whether emissions information corresponds to the correct producing installation and reporting period. Finance assesses certificate exposure and funding needed to meet associated obligations. A common register of suppliers and production installations can connect these responsibilities and support checks against customs and purchasing records.
Traceability issues when distributors change manufacturing sources
Distributors can add traceability complexity because the contractual seller may not operate the factory that produced the goods. If a distributor changes its manufacturing source during the year, importers need to establish which installation supplied each delivery. They also need to confirm whether associated emissions information remains applicable.
A corporate sustainability report alone cannot establish this connection. Importers need records linking relevant goods to producing installations and identifying emissions information applicable to the specific reporting period used in declarations.
Using verification reports correctly in declarations
Before using any verification report in a declaration, importers should examine its scope. The producing installation, goods covered, reporting period and verification conclusion must match the information supporting reported imports. Where a report is corrected or replaced, importers should track revisions to prevent obsolete versions from remaining in active calculation spreadsheets.
Earlier versions should remain accessible through a controlled record history. These procedures are described as recommended management controls rather than a requirement for every importer to repeat a factory audit independently. The importer’s task is to use verified information correctly while maintaining a defensible link between that information and imported goods.
Documentation retention for potential EU authority review
EU authorities can review submitted declarations alongside associated verification information. Importers therefore need sufficient documentation to explain how figures used in declarations relate to purchases and customs records. Retention of this documentation supports responses during any review of CBAM reporting.
Commercial arrangements for exporters supplying EU customers
For exporters in Southeast Europe, clearly identifying producing installations can support EU customer compliance needs. Agreeing data-delivery schedules and assigning responsibility for corrections can make transactions easier for EU customers managing CBAM obligations. These arrangements do not necessarily require changes to production technology.
The arrangements depend on reliable information flows between manufacturers, any distributors and importing customers. They also rely on procedures establishing which emissions records apply to each delivery into the EU market.
The first annual declaration covering 2026 imports requires importers to connect factory-level evidence with goods entered into the EU market. A verified factory report remains useful only when an importer can demonstrate it corresponds to products and installations covered by its declaration.
