What is the carbon footprint of a spark plug, and is it covered by CBAM?
A spark plug has a steel shell, a fired alumina ceramic insulator, a nickel alloy electrode and sometimes a precious metal tip. The ceramic firing and the metals carry most of the footprint. Spark plugs fall under CN 8511, which is not on the CBAM list.
What to include
- Steel shell, nickel alloy and any iridium or platinum tip.
- Alumina powder and the kiln fuel to fire insulators.
- Machining, plating and assembly electricity.
For EU buyers
No CBAM declaration is needed for CN 8511 goods, but car makers still ask for a product footprint.
What Senseible does here
Senseible reads bills, fuel invoices and production records into dated, fingerprinted records, so the figure you send a buyer can be traced to its documents.
