A single missing supplier certificate can hold a shipment at the dock, stall a product launch, and surface as a gap during a customer audit. When suppliers go silent on REACH declarations, RoHS certificates, or PFAS disclosures, the exposure is rarely a relationship problem. It is a structural failure in how evidence requests are built, routed, and tracked, and it compounds across every tier of the supply chain. This analysis breaks down the four root causes of supplier non-response and the real operational cost of chasing compliance evidence by email and spreadsheet: version chaos, no audit trail, and no visibility into which parts still lack data.
