Key sectors

Components & parts
EV & batteries
Tyres & rubber
Aftermarket
Tooling

What buyers should check

Require IATF 16949 quality certification for any component that touches vehicle safety
Ask for PPAP documentation and sample parts before committing to volume production
Assess tooling ownership, lead times, and capacity for scaling order volumes
Check compliance with destination-market emissions and safety regulations (e.g. ECE, EPA)

What suppliers should prepare

Maintain IATF 16949 and ISO 9001 certification and be ready to share audit history
Provide clear PPAP or equivalent documentation packages for new buyer qualification
Detail EV and battery capabilities separately, since buyers increasingly split ICE and EV sourcing
Offer flexible tooling and minimum order terms to win aftermarket and tier-2 business

Compliance & trade notes

Vehicle components typically require IATF 16949 quality management certification plus destination-specific type-approval, emissions, and safety marks before they can be installed or resold.

Frequently asked questions

Ask for the IATF 16949 certificate number and validate it through the certification body's IATF database, then review the supplier's APQP timeline and a sample PPAP package including dimensional reports and PSW. A remote or on-site process audit against the CSRs (customer-specific requirements) of the relevant OEM is standard for safety-critical parts.

Confirm UN 38.3 transport testing for lithium cells, IEC 62660 or equivalent cycle-life data, and whether the supplier can trace cathode materials for emerging battery-passport rules in the EU. Thermal-runaway and BMS validation reports are increasingly requested before nomination.

Tier suppliers concentrate around Germany's Baden-Württemberg and Bavaria, Mexico's Bajío corridor (Guanajuato, Querétaro), China's Yangtze Delta, and India's Chennai–Pune belt. Aftermarket and tyre production is especially strong in Turkey and Taiwan.
