# What product carbon data should a Moroccan wiring harness exporter prepare for EU car makers?

Canonical: https://senseible.earth/answers/tangier-wiring-harness-exporter-buyer-data

A cradle to gate figure per harness or per kilogram, with copper, PVC and connector shares shown separately, plus your plant's electricity per harness. Copper usually dominates, so a real figure from your wire or rod supplier matters most. Use the same allocation rule for every harness family.

## Bill of materials

- Copper conductor: kg per harness x the supplier's figure per kg.
- Insulation and sheathing: PVC or other polymers.
- Connectors, terminals and tapes from supplier data or labelled averages.

## Your plant

Cutting, crimping and assembly power, split by harness family by labour or machine hours, using Morocco's grid factor.

## Transport

Inbound copper and components and outbound trucks to Spain or ferries to Europe, from freight records.

## What Senseible does here

Senseible reads fuel, electricity and freight invoices into a dated, fingerprinted record per site, so each figure you send a buyer can be traced back to the documents behind it.
