- 01 · Specification intake
- Turn a part reference into a sourcing line with drawing revision, thread pitch, seat profile and intended vehicle or wheel. Keep unconfirmed interfaces on an open-questions list.
- 02 · Comparable supplier quotations
- Compare unit price, currency, named Incoterm place, packaging, MOQ and exclusions. A single supplier simplifies lot tracking. Splitting sources can reduce dependency and requires a separate sample record for each supplier.
- 03 · Sample coordination
- Link the delivered sample to the drawing and quote revision. For a centering ring, identify the wheel center bore and hub pilot separately. For a sample specified as 66.6 mm outside diameter and 57.1 mm inside diameter, record both measured diameters, the depth and chamfer against the drawing tolerance. For a spacer, attach the pitch circle diameter (PCD), resulting wheel offset (ET) and any radial runout or load rating checks agreed for that configuration.
- 04 · Inspection coordination
- Give the appointed inspector the approved sample, agreed lot definition and acceptance criteria. Supplier test reports and third-party results retain their own issuer and scope.
- 05 · Dispatch paperwork
- Reconcile part references, units per carton and carton totals with the order. The named freight carrier and customs broker handle their respective bookings and declarations.
