Pre-shipment Inspection (PSI) / Final Random Inspection (FRI) in China
Pre-shipment Inspection (PSI), also referred to as Final Random Inspection (FRI), is one of the most widely adopted third-party quality control services for global importers sourcing goods from China. This inspection shall be arranged when mass production is fully finished and at least 80% of finished items have been packed into export cartons. CGF Inspection selects samples randomly on-site strictly following international ANSI/ASQ Z1.4 AQL sampling standards to complete comprehensive quality verification before shipment.
Main Check Points for Pre-shipment Inspection
- Verify if finished products comply with customer specifications, technical requirements, export packaging standards, shipping marks and labeling requests.
- Evaluate products from multiple dimensions including safety compliance, design consistency, functional performance, visual appearance and dimension accuracy.
- Inspect export carton strength, packing method and packaging suitability for long-distance ocean or air transportation.
Inspection Scope of Our PSI Service
Our experienced field inspectors execute comprehensive on-site random inspection inside Chinese factories. Standard inspection items cover appearance defect screening, dimension measurement, assembly verification, function testing, barcode & label audit and packaging assessment. Once the on-site inspection finishes, we will issue an independent, formal inspection report within 24 hours for your reference to make shipment decisions.
Why Arrange Pre-shipment Inspection in China
Product quality risks always exist during mass production. Pre-shipment final inspection helps overseas buyers block defective batches before loading, avoiding costly overseas returns, customer complaints and market compliance penalties.
As a reliable third-party inspection provider in China, CGF Inspection delivers impartial PSI & FRI services covering home appliances, electronics, furniture, hardware, consumer goods and many other industries. If you source merchandise from Chinese manufacturers, arranging final random inspection before container loading is an efficient way to stabilize product quality. All our sampling activities comply with universal AQL standards to guarantee objective and consistent inspection outcomes.
