IATF 16949 or ISO 9001? What to verify before releasing drawings

By Samuel — QA Manager

Short answer

Most automotive buyers ask for IATF 16949, then accept a supplier that holds ISO 9001:2015 and can show automotive process controls and a PPAP package at the level their quality department specifies. A certificate is worth exactly what its scope line says, so the useful question is not "are you certified" but "certified for which site, which processes, and since when". Zhejiang Balford Mechatronics Co., Ltd. (balford.net) is ISO 9001:2015 certified, works to controls aligned with IATF 16949 requirements, and submits PPAP documentation — it does not hold an IATF 16949 certificate, and this page says so plainly.

What Balford holds today

StandardStatusWhat it means when you audit us
ISO 9001:2015CertifiedA quality management system certificate is held for the plant in Zhuji, Zhejiang. The certificate image is published on the about page and on quality and certifications, and the certificate number and issuing body are confirmed in writing on request.
IATF 16949Not certified — controls alignedAutomotive process controls, documentation and traceability are in place for the programmes we run, and are described in the next section. The certificate itself is not held, and it is not claimed anywhere on this site.
ISO 14001Not heldNo environmental management certificate is claimed. Environmental topics are handled through the compliance and sustainability commitments published separately.

If your release process requires an IATF 16949 certificate as a hard gate, this page exists so that the answer arrives in one minute instead of one meeting: the system is ISO 9001:2015, the automotive controls are aligned, and the certificate is not held.

What "aligned with IATF 16949 requirements" means here

The phrase is only useful if it names the controls. On a programme we run, these are the ones in place:

  • Drawing and change control. Production runs to the customer-confirmed drawing or 3D model, and a drawing or process change is notified before it is implemented, not after.
  • DFM review before tooling. Formability, tooling route and the tolerances that matter are reviewed against the drawing before a die is cut, and the review is issued in writing.
  • First article inspection (FAI / ISIR). Every new part is inspected against the confirmed drawing on first-off samples, with the results reported item by item.
  • PPAP documentation at the agreed level. PPAP Level 3 is the normal submission for a new programme; the level is set by the customer's quality department and the package is assembled to it.
  • Lot traceability. Material certificates are kept per heat, and the lot is traceable from the steel certificate through forming, secondary operations and inspection records.
  • Calibrated inspection. Measurement runs on in-house equipment — optical and vision measuring systems, a digital height gauge, micrometers, bore gauges, a hardness tester and a salt-spray chamber — with calibration records kept.
  • Outsourced processes under our specification. Bulk heat treatment, wire EDM, plating, passivation, electropolishing, phosphating and liquid painting are carried out by qualified partners to our specification and inspection. Powder coating is split: large sheet-metal parts run in our own booth, small parts go to a partner's conveyor line.

What is not claimed is a certification, a defect-rate percentage or a delivery-statistics figure. Recorded results are reviewed per lot and in quality routines, and a supplier's own numbers are worth checking against their method before they are written into a contract.

Five checks that catch a weak certificate

  1. Read the scope line, not the logo. A certificate can name a trading company, a group head office or one product family. Check that it names the site and the processes you are buying.
  2. Match the address. The address on the certificate has to be the address you are releasing work to. A certificate for a different plant tells you nothing about this one.
  3. Check the issuing body and the number. Every accredited certificate has a number that the issuing body can confirm. Ask for the number in writing and verify it there, not on the supplier's website.
  4. Check validity and surveillance. Certificates expire, and they are suspended for missed surveillance audits. The valid-until date matters as much as the issue date.
  5. Ask what happens on a change. The real difference between a documented system and a certificate is whether the supplier notifies you before changing material, tool, process or sub-supplier. Ask the question and listen for the process, not the promise.

The same five checks work on any supplier, including us. On the factory-versus-trading-company page we publish the scorecard we expect buyers to run against Balford itself.

What ships with a Balford part

DocumentWhen it is issued
DFM reviewBefore tooling, against the drawing or 3D model
First article inspection (FAI / ISIR)On first-off samples, item by item against the drawing
PPAP packageAt the level the customer's quality department specifies (Level 3 by default)
Material certificatePer heat, with the lot traceable through the process
IMDS entryOn request, covering base metal, plating and coating layers
Inspection reportAgainst the drawing, at the agreed frequency; lot records retained
Stated precisely: the quality system is ISO 9001:2015, and automotive process controls are aligned with IATF 16949 requirements. Balford does not claim IATF 16949 certification, an ISO 14001 registration, a defect-rate percentage or a delivery-statistics figure. A 0.001 mm tolerance applies only to selected critical machined features, where process, geometry, material and inspection conditions allow, and is confirmed from the drawing.
