In-Process Inspection

In-Process Inspection refers to quality inspection of semi-finished products, work-in-progress, or key processes during the manufacturing process, rather than relying solely on final shipment inspection. Its purpose is to detect quality deviations early in production, prevent batches of nonconforming products from flowing into the next process, and thereby reduce rework and scrap costs. In foreign trade, in-process inspection is common in orders where customers have high requirements for factory production progress and quality, especially in industries such as machinery, electronics, and textiles. Buyers and sellers usually specify in the contract or quality agreement the inspection points, sampling standards (such as AQL), inspecting party (customer, third-party inspection company, or factory QC), and handling of nonconformities. Note: In-process inspection does not replace final inspection and pre-shipment inspection; the three should be used in combination. If the customer designates a third party for in-process inspection, the cost bearing and inspection time should be agreed in advance to avoid affecting delivery. The difference from 'Final Inspection' is that in-process inspection occurs mid-production, while final inspection occurs after all work is completed; the difference from 'First Article Inspection' is that first article inspection only targets the first product, while in-process inspection covers multiple points in mass production.
