Consistent quality is the result of a structured inspection process, not luck. Reliable manufacturers apply quality control at three stages.
IQC (Incoming Quality Control) verifies raw materials before production. IPQC (In-Process Quality Control) monitors the line during manufacturing. OQC (Outgoing Quality Control) inspects finished goods before shipment.
Ask your supplier for inspection reports and, for critical orders, consider a third-party inspection before the goods leave the factory.
