Most businesses know that it’s vital to ensure that orders are fulfilled correctly before goods are shipped. However, not all businesses take advantage of a powerful measure to verify that your production orders meet all desired and required standards: the pre-shipment inspection (PSI).
The PSI, a comprehensive on-site inspection, is conducted when production is 80-100% complete. It plays an important role in safeguarding businesses against costly mistakes.
What Is a Pre-Shipment Inspection?
A pre-shipment inspection is a systematic and on-site inspection of randomly selected units from all batches of an order, conducted when production is nearing completion, typically at the 80-100% stage. This inspection serves as a final quality check to ensure that the production order has been executed correctly and that the products meet the specified standards.
A Brief History of the Pre-Shipment Inspection
The concept of pre-shipment inspections can be traced back to the mid-20th century when international trade began to flourish rapidly. The practice was officially introduced in 1994 under the General Agreement on Tariffs and Trade (GATT) when international organizations and trade agreements recognized the importance of standardizing inspection processes.
Why Perform a Pre-Shipment Inspection?
- Ensure Adherence to Specifications – Verify that suppliers have met all agreed-upon specifications through meticulously examining product dimensions, materials, construction, colors, labeling, and overall appearance.
- Reduce Costly Risks and Delays – Conducting a PSI during the final stages of production allows businesses to swiftly rectify any identified issues.
- Avoid Returns and Protect Brand Image – A successful PSI reduces the likelihood of defective products reaching the market and being returned by dissatisfied customers.
- Maintain Supplier Oversight – Verify the quality of products directly at the source, mitigating the risk of paying for defective goods.
How Does a Pre-Shipment Inspection Work?
Before beginning a PSI, inspectors follow internationally recognized statistical sampling procedures to randomly select product samples. The inspector also defines an Acceptable Quality Limit.
The inspection covers:
- Workmanship Defects Checks – Overall workmanship examined to identify visible defects, classified by severity.
- Product Specifications Checks – Dimensions, weight, colors, style, construction, artwork, labels verified against samples and specifications.
- Function and Safety Test – Functional testing for garments, apparel, and footwear; mechanical and electrical safety tests for products with moving parts or electrical components.
- Packing and Packaging Checks – Unit packing, inner packing, outer packing, export carton dimensions, weights, and shipping marks reviewed.
Other Inspections
- Initial Production Checks (IPCs) – Help identify and address issues early on
- During Production (DUPRO) Inspections – Performed when production is 20-80% complete
- Container Loading Checks (CLC) – Guarantee safe and secure transportation
- Production Monitoring (PM) – Provides real-time oversight and accountability
- Pre-Customs Clearance Inspections (PEO) – Ensure compliance with customs regulations
