Recheck the Commission page and state-of-play material immediately before publication. Actual-emissions reporting under EU CBAM depends on more than a producer’s calculation. The Commission’s verification guidance says declarations based on actual emissions require an independent verifier accredited by an EU national accreditation body, or NAB. The verifier’s role is to provide reasonable assurance that the embedded-emissions calculation is correct. That makes accreditation a practical dependency for producers, importers and verification firms preparing for definitive-period declarations. It also creates a timing issue: the legal framework is established, while the network of providers able to accept applications is still developing. ### What an accredited verifier does The non-EU installation operator remains responsible for monitoring and calculating emissions under the applicable CBAM methods. The accredited verifier then examines the monitoring approach, calculations and supporting evidence before issuing a verification report for the installation. The operator transmits the verified data and report through the CBAM Registry. The declarant can retrieve that information for its declaration. The Commission or the competent national authority may review the material, and the national authority may take enforcement action where appropriate. This sequence matters for supplier onboarding. A declarant should not treat an emissions spreadsheet as equivalent to verified installation data. The calculation, evidence trail, verifier scope and Registry transfer all need to work together. ### Where verification companies apply EU NABs—and EEA NABs after the relevant EEA incorporation—are the bodies competent to grant CBAM accreditation. An EU- or EEA-established verification company will generally apply to its home NAB. If that NAB does not offer the service, another NAB may be available. The route is different for a third-country verification company. Commission guidance says it may apply to any NAB offering the service. That does not mean every NAB accepts such applications, or that acceptance today guarantees the activity scope a company needs. Before choosing a route, the applicant should confirm the live NAB offer, applicant eligibility, relevant activity scope and current application process. ### What the July snapshot shows The Commission’s 10 July 2026 state-of-play table was a capacity snapshot, not an accreditation certificate or permanent legal classification. It reported 24 NABs agreeing to provide CBAM accreditation, 11 ready to accept applications, seven agreeing to accredit third-country applicants and four already accepting third-country applications `(O; 10 July 2026 snapshot)`. Italy, the Netherlands, Poland and Sweden were shown as accepting third-country applications at that date `(O; 10 July 2026 snapshot)`. These names must not be carried forward as a fixed referral list. Provider readiness can change, and a general willingness to accept applications does not confirm accreditation for a particular verification activity. The guidance also indicated that the first CBAM verifier accreditations were expected around September 2026\. That expectation is time-sensitive and must be refreshed before publication or operational reliance. ### Build the verification route before it becomes critical Importers using actual values should ask suppliers which installation will report, who owns the Monitoring Plan, how records will be preserved and how verified data will reach the Registry. Verification firms should identify the appropriate NAB and confirm the application route directly. Producers should retain calculation files, process evidence and source records in a form a verifier can test. Run a live accreditation-path check instead of relying on a saved July table. Open the current Commission verifier page, confirm the NAB’s current position and document the date and scope of the check. Then align supplier, verifier and Registry responsibilities before the declaration workflow depends on them. **Source note:** This article explains the Commission verification page and the 10 July 2026 accreditation snapshot `(G)/(O)`. It does not replace the governing CBAM legislation, an NAB decision or an accreditation certificate. ### Who this reaches **If you import.** A supplier's emissions spreadsheet cannot support a declaration based on actual emissions. You need data verified by a verifier accredited by an EU national accreditation body, retrieved through the CBAM Registry. **If you export to the EU.** This reaches you directly. You remain responsible for monitoring and calculating emissions under the applicable CBAM methods, and you transmit the verified data and the verification report through the Registry for your customer to retrieve. **The date that matters.** 10 July 2026\. The Commission's state-of-play snapshot of accreditation capacity dates from then, and provider availability was still changing quickly. **Do this now.** Check the Commission's verification page and the current state-of-play material before relying on any verifier's status or commissioning verification work. ### Source European Commission, [“Verification of CBAM emissions”](https://taxation-customs.ec.europa.eu/carbon-border-adjustment-mechanism/cbam-verification%5Fen?ref=cms.cbam.help), and [“State-of-play CBAM accreditation”](https://taxation-customs.ec.europa.eu/document/download/a782dacf-ab68-44cc-986c-28fd1b4daa94%5Fen?filename=State-of-play%20CBAM%20accreditation.pdf&ref=cms.cbam.help), dated 10 July 2026 `(G)/(O)`. **Source status and class:** Official Commission guidance and a dated operational capacity snapshot `(G)/(O)`.
