What does FQC cover? Final Quality Control (FQC) involves spot-checking finished goods before shipment. Inspections cover appearance (color differences, stains), functionality (magnetic closures, opening/closing mechanisms), and dimensions (tolerances) based on AQL standards. The core responsibility of FQC is to ensure that “non-conforming finished goods are not shipped.”
What does IPQC cover? In-Process Quality Control (IPQC) involves inspecting work-in-progress (WIP) across various stages—printing, die-cutting, paper mounting, and assembly. First-article inspection (checking the first unit of each process) is critical. The core responsibility of IPQC is to ensure that “problematic processes do not proceed to the next stage.”
Inspection isn’t about nitpicking; it’s about insuring the bulk shipment. Ask yourself: if there’s a problem with this batch, would you rather discover it at the factory or after it has crossed the ocean and reached the customer?
How is sampling determined? Sampling plans are based on batch size (using AQL tables): normal inspection, tightened inspection (when issues arise), and reduced inspection (after consistent compliance). Records of sampling results must be kept. Sampling details prioritize “traceability.”
What about OQC and third-party inspections? Outgoing Quality Control (OQC) and third-party inspections involve spot-checking against customer standards (e.g., AQL 2.5); the inspection report serves as the basis for shipment release. Coordination for inspections requires confirming standards before scheduling.
Quality control is not merely the “final hurdle” before shipment but a “process management” approach spanning the entire workflow: incoming materials, production processes, and outgoing shipments. A lapse at any stage can lead to customer complaints. This article clearly outlines the quality inspection process for packaging boxes, making it easy for foreign trade clients to learn and implement.
What does IQC cover? Incoming Quality Control (IQC) checks the quality of incoming materials such as paperboard, facing paper, ink, and hardware components. Parameters like grammage, moisture content, and batch consistency are spot-checked against standards. The core responsibility of IQC is to ensure that “non-conforming materials do not enter the factory.”
