PPAP for Automotive Components from Chinese Factories
1 resources tagged with "Ppap"
PPAP (Production Part Approval Process) is the automotive supply chain's gate for proving a Chinese factory can make a part consistently before mass production, and it sits inside an IATF 16949 quality system. The standard defines five submission levels — Level 3 (full documentation plus sample) is the common requirement, while Level 5 demands review at the supplier's site. Buyers sourcing automotive electronics from China need to confirm the factory's IATF 16949 certificate is genuine and that they can actually produce a complete PPAP package, not just sign off on it.
PPAP is a documented evidence package — dimensional results, material certs, process flow, control plan, PSW — that demonstrates a part meets spec at production conditions. The pitfall with Chinese suppliers is a valid-looking IATF 16949 certificate paired with a factory that has never assembled a real PPAP submission; verify the certificate number with the issuing body.

FAQ
What PPAP level do automotive buyers usually require?
Level 3 is the default for new parts — it includes the full documentation set plus production samples. Level 5 keeps records at the supplier for on-site review and is used for high-risk or safety-critical parts.
How do I verify a Chinese factory's IATF 16949 certificate?
Check the certificate number against the IATF database and the certification body's registry, and confirm the scope actually covers your part type. A genuine certificate plus a real PPAP capability audit is the only reliable proof, since fake certificates circulate widely.
