If you purchased more CBAM certificates than needed, Art. 23 of Reg. (EU) 2023/956 allows you to request a buyback of the excess. The buyback must be requested before 31 October of the year in which certificates were surrendered. The repurchase price equals the price you originally paid. But there is a limit: the total number of certificates you can buy back cannot exceed the total you were obliged to purchase under the quarterly obligation (Art. 23(2)). CBAMCheck's certificate estimation helps you avoid overbuying in the first place.

The buyback window closes on 31 October. After this date, excess certificates cannot be repurchased. Mark the deadline in your compliance calendar.
Art. 23(2) caps the buyback at one-third of the total certificates purchased during the year. If you bought 300 certificates and needed 200, you can buy back up to 100 (one-third of 300) — which happens to cover the excess. But if you massively overbought, the cap may bite.
While conservative estimates are prudent, massive overbuying ties up capital. CBAMCheck's estimation reduces uncertainty, and the quarterly purchase structure (Art. 22(2)) allows you to adjust throughout the year.

The EU CBAM Registry (Art. 14) requires you to submit total embedded emissions, number of certificates and carbon price documentation. It does not calculate these for you. You must arrive with the numbers ready.
CBAMCheck takes your import data (tonnes, CN codes, country of origin) and generates the embedded emissions calculation, certificate estimation, carbon price documentation and all supporting records. You download the dossier and use it to complete your declaration in the CBAM Registry.
Art. 26 of Reg. (EU) 2023/956 sets the penalties.
Art. 26(1): an authorised CBAM declarant who fails to surrender the required certificates by 30 September faces a penalty identical to the excess emissions penalty under Art. 16(3) of Directive 2003/87/EC, increased per Art. 16(4). The penalty applies per certificate not surrendered. Payment does not release the obligation to surrender outstanding certificates (Art. 26(3)).
Art. 26(2): anyone introducing goods without authorisation faces a penalty of 3 to 5 times the standard penalty, depending on duration, gravity, scope, intent and cooperation. Also applies to importers exceeding the de minimis threshold (50 tonnes, Art. 2a) without authorisation (Art. 26(2a)).
