What are the CBAM default values for CN 7318 15 52?

The EU publishes default values for CN 7318 15 52 for 32 countries of origin, from 1.37 to 8.23 tonnes of CO₂e per tonne.

Embedded emissions in tonnes of CO₂e per tonne of the good, as published on 31 Jul 2026. They are shown before the mark-up for the year, which is added when they are used. See the mark-up by year

Only the direct emissions of this good count towards the certificates due.

What are the CBAM benchmarks for CN 7318 15 52?

The benchmark, multiplied by the CBAM factor for the year, is the free allocation deducted from the certificates due. It depends on whether the embedded emissions come from default values or from the producer’s verified actual data. See the CBAM factor by year

Production routeWith default valuesWith actual emissions
1.154(2026–2027)0.038
1.116(2028–2030)

In tonnes of CO₂e per tonne of the good. A year range limits a value to goods produced in those years.

What do the production routes mean?

A production route is the way a good is made. Default values and benchmarks can differ from one route to another.
