CBAM has entered its definitive regime. The reporting output may be visible, but the operational challenge starts upstream: identifying affected imports and building a reliable flow from customs and supplier data to the final declaration.
In brief
- The CBAM definitive regime applies from 1 January 2026.
- Compliance connects customs, product, supplier and emissions data across teams and systems.
- A controlled data pipeline makes missing information, changes and approvals visible before reporting.
The EU Carbon Border Adjustment Mechanism entered its definitive regime on 1 January 2026. For affected importers, CBAM now includes authorisation, reporting and certificate obligations linked to the embedded emissions of imported goods.
If the underlying data flow depends on manual collection at the end of the period, compliance becomes slow, difficult to verify and highly dependent on individual employees.
CBAM is a recurring data process
CBAM covers selected goods in cement, iron and steel, aluminium, fertilisers, electricity and hydrogen. Under the current definitive regime, EU importers or indirect customs representatives importing more than the single mass-based threshold of 50 tonnes of CBAM goods must apply for authorised CBAM declarant status. Applicability must still be assessed against the detailed rules and exceptions for the specific goods and flow.
For affected imports, the business needs to connect information that may sit in several places:
- customs declarations and commodity data
- commercial invoices and purchase data
- quantities, weights and country information
- supplier and installation information
- embedded-emissions data
- evidence of any carbon price already paid
- reporting and certificate records
These inputs are not normally created by one team or stored in one system. CBAM should therefore be designed as a cross-functional operating process rather than a periodic compliance exercise.
The common failure points are upstream
1. Affected transactions are not identified consistently
If goods are identified manually at the end of the period, omissions and inconsistent assessments become more likely. The process needs a repeatable way to detect potentially relevant imports and route uncertain cases for review.
2. Data arrives in different formats
Supplier documents, customs records and ERP data rarely use the same structure or identifiers. A transaction may need to be matched across an invoice, a declaration and supporting emissions information.
3. Required fields are missing
Operational documents are created to move and clear goods. They do not automatically contain every field needed for CBAM. Missing information must be detected early enough to request it from the correct party.
4. Corrections lose their audit trail
When data is copied between spreadsheets and email threads, it becomes difficult to explain which source was used, what changed and who approved the final value.
5. The process cannot scale
A manual process may work for a limited number of imports. It becomes fragile when volumes, suppliers, products and reporting requirements increase.
Build a controlled CBAM data pipeline
Capture
Receive the customs, commercial and supporting documents used in the process. Preserve the connection to the original source.
Structure
Extract relevant information and convert it into a consistent data model. Maintain stable references across documents and systems.
Match
Connect import transactions with the relevant supplier, product and emissions information. Send ambiguous matches to review rather than accepting them silently.
Validate
Check completeness, formats, permitted values and relationships between fields. Make missing information visible before the reporting deadline.
Approve and deliver
Let responsible users confirm exceptions and deliver approved data to the reporting process or solution in the required format.
Retain evidence
Keep the source, transformation and approval history needed to explain the reported data later.
Where Edentri supports the process
Edentri can capture information from customs declarations, SAD documents and other trade documentation, structure and validate it, and store it in a dedicated CBAM-ready database. This creates a controlled data foundation for the customer’s reporting and compliance process.
The scope should start with the customer’s actual documents, systems and responsibilities. A bounded first flow keeps the upfront investment low and reveals where automation creates immediate value. Additional suppliers, document types and validation rules can then be added over time. Learn more about Edentri’s data capture and processing for CBAM.
A practical starting point
Select one affected product group or import flow and answer five questions:
- How are potentially relevant imports identified?
- Which source provides each required field?
- How are customs, invoice and emissions records linked?
- Which checks can be automated, and which decisions require a specialist?
- What evidence must be retained for later review?
Build and test that flow with real operational data. The result should be a repeatable process with visible exceptions — not a perfect-looking spreadsheet that only one person understands.
Frequently asked questions
When did the CBAM definitive regime start?
The definitive regime applies from 1 January 2026. It follows the transitional phase that ran from 2023 through 2025.
Which sectors are covered by CBAM?
CBAM applies to selected goods in cement, iron and steel, aluminium, fertilisers, electricity and hydrogen. The detailed product scope is determined by the applicable commodity codes and rules.
Can CBAM data preparation be automated?
Parts of the process can be automated, including document capture, extraction, matching and validation. Specialist review remains important for uncertain transactions, missing supplier data and compliance decisions.
