  • There is a change in construction material
  • Sub-supplier or material source change
  • Change in part production process
  • Parts produced at a new or additional location
  • Correction in previous discrepancy

How long will it take to complete a PPAP?

Many factors determine the PPAP approval time and it can be sometimes time-consuming due to the huge number of parts, suppliers, the number of materials in each part and so on. Many companies have outsourced their PPAP process to experts such as ComplianceXL, who can deliver dedicated PPAP teams working as an extended arm to clients.

When is PPAP required?

  • Change in source of subcontracted part material or services
  • Correction in previous discrepancy
  • Engineering changes
  • Production from new or modified tools or change in process
  • Use of alternate or optional materials
  • Change of manufacturing location
  • Initial submission for new item-vendor combination development
