Documented steps
Identify the CN codes of the goods imported and check them against CBAM's covered sectors in Annex I of Regulation (EU) 2023/956: cement, iron and steel, aluminium, fertilisers, hydrogen, electricity.
Open the CBAM sectors page (taxation-customs.ec.europa.eu/carbon-border-adjustment-mechanism/cbam-sectors_en) and download the sector factsheet for each relevant sector to confirm the exact CN code lists; the sector page itself does not carry the full 8-digit annex.
If the goods are electricity or hydrogen, treat the importer as in scope regardless of quantity: Article 2a(4) as inserted by Regulation (EU) 2025/2083 excludes electricity and hydrogen from the de minimis exemption.
For cement, iron and steel, aluminium or fertilisers, sum the net mass of all CBAM goods across all applicable CN codes imported by that importer, aggregated over the whole calendar year, not per shipment and not per CN code.
Compare the aggregated annual net mass against the single mass-based threshold of 50 tonnes (Article 2a(1), Annex VII point 1, as inserted by Regulation (EU) 2025/2083).
If cumulative annual net mass does not exceed 50 tonnes, treat the importer as exempt for that calendar year: no authorisation, no declaration, no certificates.
If the importer expects to exceed 50 tonnes during the year, treat authorised CBAM declarant status as required before importing the goods that cross the threshold (Article 5(1)/(1b)).
Re-run this determination every calendar year; the exemption is assessed per importer per calendar year and is not a permanent status.
Cross-check the CBAM FAQ and guidance hub for edge cases such as processed or downstream goods and mixed consignments before concluding.

Known gotchas
The 50-tonne threshold is a 2025 Omnibus addition (Regulation (EU) 2025/2083, Article 2a). It did not exist in the 2023-2025 transitional period, when all importers of covered goods reported regardless of volume.
The threshold is cumulative per importer per calendar year across all in-scope CN codes. It is not a per-shipment de minimis, so many small consignments can still breach it.
Electricity and hydrogen get no de minimis relief at all under Article 2a(4). There is no wait-and-see option for those two sectors.
An importer under the threshold must still monitor its own volumes; if it later expects to cross 50 tonnes mid-year it must apply for authorisation before importing the goods that push it over.
Do not assume transitional-period reporting scope equals definitive-regime authorisation scope. The mass threshold changes who needs authorisation, not what counts as a CBAM good.
The full 8-digit CN code annex is authoritative only in Annex I of Regulation (EU) 2023/956 as amended; sector names on the Commission website are a summary, not the legal list.
