Material Traceability	PMI testing, material certs	Test reports, batch tracking	20%	25%
Production Capacity	Monthly output, lead time	Production records, references	10%	20%
After-Sales Support	Warranty terms, response time	Contract review, customer references	5%	20%

Evaluation weights vary by buyer segment. Tier 1 OEMs prioritize certification and capability; aftermarket buyers emphasize capacity and support ^[5].

PMI (Positive Material Identification) testing has become mandatory for many automotive valve applications, particularly in safety-critical systems. This non-destructive testing verifies the actual metallurgical composition of valve balls, ensuring they match specified material grades. Suppliers without in-house PMI capabilities must partner with NABL-accredited laboratories, adding cost and lead time to each production batch ^[5].

CNC automation represents another critical differentiator. Automated manufacturing ensures dimensional consistency across production batches, which is essential for PPAP approval and ongoing quality compliance. Manual or semi-automated production may suffice for low-volume aftermarket applications but will struggle to meet Tier 1 volume and consistency requirements.

Raw material inventory buffers are essential for supply chain resilience. Suppliers who maintain strategic raw material stockpiles can absorb supply shocks and maintain delivery commitments during market disruptions ^[5].
