Questions about CN 7318

What is the CBAM default value for CN 73181100 from China?

The official EU default value for CN 73181100 (Coach screws of iron or steel) from China is 2.738 tCO2e per tonne before the mark-up; with the 10.0% mark-up for 2026 it is 3.012 tCO2e per tonne. On 1,000 t that is about €138,454 of 2026 certificates to surrender at the published price (€82.32/t).

Which emissions count for CN 7318 under CBAM?

Only direct emissions count for iron & steel goods (Annex II of Regulation (EU) 2023/956): indirect emissions from electricity are reported but not charged.

How much mark-up is added to the CBAM default values for CN 7318?

The default value carries a regulatory mark-up of 10% in 2026, 20% in 2027 and 30% from 2028 (Implementing Regulation (EU) 2025/2621). Verified actual emissions from the installation replace the default and carry no mark-up.

How do I use actual emissions instead of the default value for CN 7318?

Ask the producing installation for its specific embedded emissions, calculated under the EU method and checked by an accredited CBAM verifier. Until then the default value for the country of origin applies.

Replace the default with verified data

Default values are a conservative fallback, not a measurement of any plant. Verified actual emissions from your supplier's installation remove the mark-up and usually lower the bill. CBAM Compliance invites your suppliers in their language, computes their figure with the official method, and produces registry-ready QReport XML.
