## What is the CBAM definitive regime?
From 1 January 2026, EU importers of “CBAM goods” — cement, iron & steel, aluminium, fertilisers, electricity, hydrogen — are under legal obligation to pay a carbon price for embedded emissions in goods produced outside the EU. Importers whose goods exceed **50 tonnes per year** must apply to become **authorised CBAM declarants**, purchasing CBAM certificates via their National Competent Authority.

## Verification & Accreditation: How to Become a CBAM Verifier
- Must be **independent, impartial, and technically competent**, accredited by an EU National Accreditation Body (NAB).
- Verifiers must register in the **CBAM Registry** via EU-based NABs after accreditation — starting **1 September 2026**. ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/carbon-border-adjustment-mechanism/cbam-verification_en?utm_source=openai))
- Only verified, actual emission data may be used by importers in their CBAM declarations (otherwise, they must rely on default values).

## What Verifiers & Operators Should Do Now
- Begin accreditation process with NABs — identify whether your NAB offers CBAM verifier accreditation or if you must apply with another Member State. ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/carbon-border-adjustment-mechanism/cbam-verification_en?utm_source=openai))
- From **1 September 2026**, register with the CBAM Registry and ensure internal verification documentation is compliant with standards.

## Why It Matters
- Declarations submitted in 2027 will rely on 2026 imports, making accurate verification essential.
- Using actual values enhances credibility and may reduce costs vs. using default emission factors if your actual emissions are relatively low.
## Example Case: A Steel Exporter in Turkey
1. Must monitor embedded emissions from the blast furnace or electric arc furnace.
2. Hire a CBAM-accredited verifier (possibly outside Turkey if no NAB offers services).
3. The verifier reviews emissions, performs audit/site visit, prepares report.
4. Importer in the EU submits verified data, purchases necessary certificates.
## Quick Checklist for Stakeholders
- [ ] Do you handle CBAM goods?
- [ ] Have you assessed whether your goods exceed the 50-tonne threshold?
- [ ] Are you ready to apply to be a declarant?
- [ ] Does your country’s NAB offer verifier accreditation? If not, plan cross-border accreditation or outsourcing.
- [ ] Train internal teams and consultants on audit and documentation standards.
Staying ahead of deadlines and ensuring accurate verification are key to avoiding penalties and maximizing competitive advantage under the CBAM regime. By following the rules, companies can turn compliance into a strategic advantage.
