Pre-Shipment Inspection (PSI) is an essential element of supply chain management. PSI is a systematic inspection of units selected at random from all batches of your order, conducted when your production is at least 80% complete. This is your final opportunity to take corrective action before your production is finished and packed; making it an effective tool to safeguard your product against costly import risks.
During PSI, inspectors will select boxes at random to confirm that product has passed functional, visual, safety, performance testing, ensure each carton bears the quantity of product ordered, the quality matches the specifications and/or approved sample provided by you, and that all packaging material contains the correct barcodes, labeling, and packing materials.
Each inspection is unique, PSI is the most important inspection because all checklists are customized, we focus on customer’s unique test request to ensure that factory strictly follow customer’s needs and specifications to produce, we can also support customer take quick action to against any mistakes that factory made during manufacturing.
For all inspections, 3CYuan uses the standard internationally recognized ANSI/ASQC Z1.4 (ISO 2859-1) statistical sampling procedure. These comprehensive criteria cover: functionality, performance, durability, overall appearance, and dimension.
