The European Commission has opened feedback on the draft delegated regulation for the sale and repurchase of CBAM certificates.

Feedback is open until 6 August 2026, based on the standard four-week Better Regulation period from the 9 July 2026 Ares publication date in the draft PDF. The live page should be checked before submission.

From February 2027, authorised CBAM declarants will buy certificates through the common central platform. The draft sets the purchase, payment, fee and repurchase rules for that system.

What The Draft Creates

The CBAM registry remains the place where authorised CBAM declarants hold certificates, submit declarations and manage certificate status.

The common central platform handles certificate payment and repurchase.

A purchase request starts in the CBAM registry. The certificate is created in the declarant's CBAM account after payment is confirmed on the common central platform.

Purchase Rules

A purchase request must cover a whole number of CBAM certificates between 1 and 99,999. The registry records the certificate quantity, certificate price, platform fee and total amount due. After a purchase request is entered, the user cannot amend it. The user can withdraw it only before payment is made on the common central platform.

Payments are made in euro and the platform fee is fixed at EUR 0.05 per CBAM certificate sold. The draft states that no other fees or charges apply to sale or repurchase.

Repurchase Rules

The repurchase procedure has tighter conditions than purchase.

A user may enter one repurchase request per year and them cannot be amended or withdrawn after it is entered. Requests following a competent-authority review are excluded from that one-request count.

The user must have complied with the 30 September surrender obligation or have been exempt for the previous calendar year.

Repurchase requests entered before 1 April, 1 July and 1 November are to be approved within 42 calendar days by the competent authority if the conditions are met.

Excess certificates can be repurchased only under the legal limit and through the annual repurchase timetable.

What Importers Should Prepare

CBAM certificate management becomes a finance and compliance process before 2027.

By February 2027, authorised CBAM declarants should test the internal handoff between customs, CBAM reporting, finance and treasury.

Importers should assign three responsibilities before the purchase window opens:

• Registry purchase requests;

• Euro payment approval;

• Certificate availability checks before surrender.

The treasury team also needs the certificate price, payment timing and expected import emissions before the annual surrender deadline.

The compliance team needs the same information to avoid buying too late or over-buying beyond the repurchase limit.
