# What are the UK CBAM default values for ferro-manganese and ferro-chrome?

Canonical: https://senseible.earth/answers/uk-cbam-ferro-manganese-chrome-default

HMRC's UK CBAM default for high-carbon ferro-manganese (7202 11) is 1.859 tCO2e per tonne and 6.149 for low-carbon ferro-manganese (7202 19 00). High-carbon ferro-chrome (7202 41) is 2.585, low-carbon ferro-chrome (7202 49) 3.157, and ferro-nickel 5.502.

## Defaults

- 7202 11 20 and 7202 11 80: ferro-manganese above 2% carbon: 1.859 tCO2e per tonne.
- 7202 19 00: ferro-manganese at or below 2% carbon: 6.149.
- 7202 41 10 and 7202 41 90: ferro-chrome above 4% carbon: 2.585.
- 7202 49 10, 50 and 90: ferro-chrome at or below 4% carbon: 3.157.
- 7202 60 00: ferro-nickel: 5.502.

## Power is left out for now

Ferro-alloy smelting is power-heavy, and the UK does not count electricity until at least 2029. The UK figure covers direct emissions such as those from reductants and other process carbon, plus any covered precursors.

## Silico-manganese is different

Ferro-silico-manganese (7202 30) and ferro-silicon (7202 21) are excepted from UK CBAM.

## What Senseible does here

Senseible reads ore, coke, reductant and power invoices by month, so a smelter's direct figure can be set against 1.859 or 2.585. We build the figure from your records and check every figure in-house; for the UK it must then be verified by a verifier accredited for UK CBAM. Have your own verifier? Send it to them.
