What is a Pre-Shipment Inspection (PSI)?
A Pre-Shipment Inspection (PSI)—often termed Final Random Inspection (FRI)—is the single most vital quality gatekeeper in the apparel supply chain. Conducted when at least 80% of the total order quantity is completely finished, pressed, folded, and packed into master shipping cartons, PSI represents the buyer’s final opportunity to catch defects before goods leave the exporting country.
Once a container departs the seaport, rectifying defect issues in destination warehouses costs up to 10 to 20 times more than fixing them in the factory. A systematic PSI guarantees that only compliant garments reach retail shelves.
The Standard Apparel PSI Procedure
Professional apparel inspectors follow a rigorous, non-negotiable inspection sequence on site:
- Carton Quantity & Stacking Verification: The inspector counts the packed cartons against the packing list and verifies batch quantities and storage conditions.
- Statistical Random Sampling: Using ISO 2859-1 sampling tables, the inspector personally selects random cartons from all layers of the warehouse pallets.
- Packaging & Barcode Check: Inspectors scan retail barcodes using handheld scanners, check polybag suffocation warnings, hangtag accuracy, and master carton shipping marks.
- On-Site Functional & Safety Testing:
- Carton Drop Test (ISTA 1A standard): Dropping a packed master carton from calculated heights to ensure packaging withstands transit shock.
- Pull Test for Snaps & Buttons: Applying 15-22 lbs (70-90 N) of calibrated tension for 10 seconds to verify fastener security.
- Seam Slippage & Stretch Recovery: Testing high-stress seams (crotch, armhole, waistband) under firm manual pull.
- Needle Detection: Passing metal detection calibration blocks and garments through calibrated 9-point search heads.
- Visual & Workmanship Inspection: Evaluating garments on inspection tables under 1,000+ lux daylight lamps for sewing, stitching, fabric, and finishing defects.
- Size & Measurement Audit: Measuring full size-spec runs across multiple sample garments to check adherence to tech-pack tolerances.
Common Apparel Defects Identified During PSI
| Defect Category | Defect Examples | Severity Level |
|---|---|---|
| Safety & Compliance | Broken needle parts, sharp pins, mold, missing fiber content label | CRITICAL (Immediate Fail) |
| Workmanship & Sewing | Open seams >5mm, broken stitches, misaligned buttons, needle holes | MAJOR (AQL 2.5) |
| Fabric & Finishing | Noticeable shade variation between panels, oil stains, color bleeding | MAJOR (AQL 2.5) |
| Cosmetic / Minor | Uncut threads <1cm, minor wrinkling, washable chalk marks | MINOR (AQL 4.0) |
What Happens If an Inspection Fails?
If the count of major or minor defects exceeds the AQL limit, the inspector issues a FAIL verdict. The buyer receives immediate photographic evidence and defect summaries. The factory is then required to perform 100% sorting, re-pressing, re-stitching, or re-cleaning, followed by a formal Re-Inspection before the shipment can be authorized for release.
