Use this guidance to find the default values to use for the aluminium sector. The values apply to each Carbon Border Adjustment Mechanism (CBAM) good, regardless of origin.
If you submit a CBAM return that uses default values, you cannot amend it later with actual emissions data.
The default values are sorted by combined nomenclature (CN) code. To find out the CN code for a good, you can use the Trade Tariff tool.
Using default values and actual emissions
You can use default values to determine emissions in your CBAM goods, including any CBAM goods used to make a final CBAM good (precursors).
You can use default values for precursor goods when using actual emissions data for relevant processes associated with turning the precursor goods into final CBAM goods.
You cannot use actual emissions data for precursor CBAM goods and default values for the final CBAM good.
Aluminium default values
Open the find and search function on your device and enter the CN code to find the default value you need.
The following values replicate those of the Force of Law notice. You must use them if you’re not reporting actual verified emissions.
