Supplier-provided
Supplier records
Record the supplier entity, actual production site and scope. When requested, match an IATF 16949 or ISO 9001 certificate to that entity, site and valid scope as quality-management evidence.
Forgeline / Sourcing Lab
The Forgeline Sourcing Lab
Trace each supplier option from fitment inputs through drawing, sample and document review. Record unresolved scope beside the price, where the buying team will see it.
Evidence before commitment
Buyer-approved
Fitment and sample check
Request a dimensioned drawing with diameter × width in inches, bolt count and PCD, ET and center bore in mm, load rating in kg and finish. For example, 18 × 8 in, 5 × 114.3 mm PCD and ET35 identify part of a request. Bore, load, caliper clearance and fastener seat still need values. This is a brief example, with no fitment approval implied.
SKU and destination
Document scope
Check if the intended market and wheel category call for evidence against UNECE R124, SAE J2530 or JWL/VIA. Track the report or approval identifier, SKU, load, dimensions, revision and covered variants.
Appointed inspection
Measurement plan
For radial and lateral runout, agree the mounting datum and where the indicator contacts the wheel. Record total indicator movement over a full rotation in mm and compare each reading with the buyer-approved limit. Identify the sample, fixture and drawing revision on the inspection record.
Commercial comparison
Quote normalization
Compare forged and cast options on the same load and fitment. Separate tooling, finish, samples, packing and named Incoterm location. Compare a stock proposal on confirmed size availability and repeat-order coverage. Compare a custom proposal on tooling ownership, sample approval and order minimums. Ask each supplier to identify the lead-time trigger.
Buyer and forwarder
Shipment file
Match purchase line, carton marks, packing list and gross weights. For mixed-container loading, ask the forwarder to confirm stack limits and how the consignees will identify each supplier’s cartons.
From brief to shipment
Clarify
Mark the application and drawing revision. Assign owners to unresolved inputs.
Compare
Bring quote lines to the same quantity, pack count and trade basis.
Verify
Track sample approval and any appointed inspection or laboratory evidence.
Coordinate
