Self-assessment tool
The Commission has developed a CBAM Self-Assessment Tool for Importers to the EU.
The tool provides importers to the EU with the possibility to get a quick overview on whether the imported goods are subject to CBAM during the transitional period, what the CBAM reporting requirements for that particular type of good are, and where to find further information.
The Commission maintains the tool to facilitate the implementation of CBAM during the transitional period until 31 December 2025. The goal is to keep the tool timely and accurate, and if errors are brought to our attention, we will try to correct them.
However, the Commission accepts no responsibility or liability with regards to the information provided by this tool. It cannot be guaranteed that the tool exactly reproduces the officially adopted legislation. Only the Official Journal of the European Union (the printed edition or the electronic edition on the EUR-Lex website) is authentic and produces legal effects.
Further information on customs obligations for importers to the EU is provided in the TARIC database.
