In import and export trade, inspection is a critical link between production and delivery. A professional third-party inspection can intercept quality risks before shipment, helping brands and buyers avoid costly returns, replacements and rework. As an established third-party inspection company, we deliver reliable inspection services with strict product quality inspection procedures for global clients. How does a standard on-site factory inspection work? What tests are carried out on site? This article outlines the complete inspection process and methods.
1. Full Procedure of On-site Factory Inspection
Our professional third-party quality inspection adopts a three-stage control system: pre-production inspection (PPI), during-production inspection (DUPRO) and final inspection (FRI). Pre-production inspection (PPI) evaluates samples, raw materials and workmanship before mass production to prevent large-scale rework. During-production inspection (DUPRO) is conducted when 20%–30% of production is finished to check stitching, bonding and consistency of mass production, so defects can be fixed at source. Final inspection (FRI) is carried out when over 80% of goods are completed, serving as the final checkpoint for most orders. Inspectors draw samples in accordance with the international AQL sampling standard, generally using General Inspection Level II with acceptance limits of 2.5/4.0. Judgement follows ANSI/ASQ Z1.4 and GB/T 2828.1 standards to ensure objective, fair and traceable results for third-party checking.
2. On-site Test Items: Visual Check & Performance Test
On-site tests include visual inspection and physical performance testing, with professional third-party testing running through the whole process. Visual and workmanship inspection covers color difference, stains, damage, skipped stitches, glue overflow, poor bonding, size symmetry, as well as correctness of packaging, hang tags and barcodes. Physical performance testing is the core part of inspection. With professional equipment such as tensile testers, abrasion testers, flexing testers and color fastness testers, our inspectors conduct tests including peel strength, abrasion resistance, flex resistance, slip resistance, tensile strength, seam strength and color fastness. For certain orders, chemical tests such as formaldehyde and heavy metal content are also available to meet safety regulations of target markets.
3. Inspection Methods: Standardized Operation & Professional Tools
All inspections follow standardized SOP. Inspectors compare goods against purchase orders and approved samples. Vernier calipers, thickness gauges and pull force gauges are used for measurement and strength testing. All findings are recorded in formal inspection reports. Non-conformities are clearly graded with on-site photos as supporting evidence for transparent judgement.
