If an imported CBAM good was produced using precursors from the EU (e.g. pig iron) – would this have to be considered in the calculation?
Yes, relevant precursors produced in the EU also need to be accounted for in the determination of the embedded emissions.
Note, however, that if a precursor stems from EU production, the carbon price already paid in the EU may also be reflected in the CBAM report. (Find more details on the report of the effective carbon price paid in the Guidance document for non-EU installations Section 6.10.).
