# Harness Atlas

> Global directory of wire harness and cable assembly manufacturers for procurement teams. Plant-centric discovery with capabilities, certifications, and verification tiers.

Harness Atlas helps buyers find and compare wire harness manufacturers worldwide. Suppliers list their company HQ and individual production plants with technical capabilities (crimping, ultrasonic welding, overmolding, etc.), certifications (IATF 16949, ISO 9001, IPC/WHMA-A-620, AS9100), and verification tiers (Self-Declared, Verified-Remote, Verified-Onsite). Buyers can filter, shortlist, compare side-by-side, and send RFQs.
