# What are the UK CBAM default values for aluminium wire and ACSR conductor?

Canonical: https://senseible.earth/answers/uk-cbam-aluminium-conductor-wire-default

HMRC's UK CBAM default for aluminium stranded conductor with a steel core, such as ACSR (7614 10 00), is 3.742 tCO2e per tonne, and 3.217 for other stranded aluminium (7614 90 00). Non-alloy aluminium wire above 7 mm (7605 11 00) is 2.360, and up to 7 mm 3.151.

## Defaults

- 7614 10 00: stranded wire and cables with steel core, not insulated: 3.742 tCO2e per tonne.
- 7614 90 00: other stranded wire and cables of aluminium: 3.217.
- 7605 11 00: non-alloy aluminium wire above 7 mm: 2.360.
- 7605 19 00: non-alloy aluminium wire up to 7 mm: 3.151.
- 7605 29 00: alloy wire up to 7 mm: 4.005.

## Insulated cable is outside

Heading 7614 covers conductors that are not electrically insulated. Insulated cables sit in chapter 85, which is not on the UK CBAM list.

## Your main precursor

Wire rod is the main precursor, and primary and secondary metal carry different emissions. Ask your rod supplier which it is and for its verified figure.

## What Senseible does here

Senseible reads wire rod purchases by supplier with your annealing fuel, so a conductor maker's own figure can be set against 3.742 or 3.217. 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.
