Comprehensive Step-by-Step Guide for Pre-Shipment Inspection of Textile Products

PHASE 1: PRE-INSPECTION PREPARATION

(Before the inspector arrives at factory)

Step 1: Document Review & Planning

  1. Gather Specification Documents:
    • Approved lab dip/swatch cards
    • Approved strike-off/print strike-off
    • Approved trim cards (zippers, buttons, threads)
    • Tech pack with detailed measurements (POM sheet)
    • Approved fabric quality standard
    • Packaging specifications (polybags, hangers, cartons)
    • Purchase Order with quantity breakdown
  2. Define AQL (Acceptable Quality Level):
    • Select appropriate AQL for defects:
      • Critical Defects: AQL 0.0 (e.g., safety issues, branding errors)
      • Major Defects: AQL 2.5 (e.g., holes, stains, wrong color)
      • Minor Defects: AQL 4.0 (e.g., loose threads, minor stitching issues)
    • Determine sample size based on MIL-STD-105E/ANSI Z1.4 tables
  3. Schedule Inspection:
    • Ensure 80-100% of order is completed and packed
    • Arrange proper lighting and workspace at factory
    • Confirm factory representative will be available

PHASE 2: ON-SITE INSPECTION PROCESS

Step 2: Initial Verification

  1. Quantity Verification:
    • Count total cartons/pieces
    • Verify packing list matches PO quantities
    • Check packing ratio (units per inner/outer carton)
  2. Carton & Packaging Check:
    • Inspect carton quality (strength, water resistance)
    • Verify shipping marks: Style #, PO #, Color, Size, QTY, Destination
    • Check barcode labels accuracy
    • Inspect inner packaging (polybags, tissue, hangers)

Step 3: Random Sampling

  1. Select Sample Pieces:
    • Use random sampling method across colors, sizes, and cartons
    • Select sample size according to AQL table
    • Ensure samples represent entire production run

Step 4: Visual & Dimensional Inspection

  1. Visual Inspection – General:
    • Check overall appearance and presentation
    • Verify against approved sample/prototype
    • Look for obvious defects from 3 feet/1 meter distance
  2. Fabric Quality Check:
    • Color: Check against approved lab dips under proper lighting (D65)
    • Shading: Compare color consistency within garment and across panels
    • Fabric Defects: Identify holes, stains, slubs, yarn variations, knitting defects
    • Hand Feel: Verify fabric weight, texture, and drape match standard
  3. Measurement Verification (POM Check):
    • Measure 3 pieces per size against tech pack tolerances:
      • Key measurements: Chest/Bust, Waist, Hip, Length, Sleeve
      • Use calibrated measuring tape on flat surface
    • Check symmetry (sleeve lengths, shoulder seams, side seams)

Step 5: Construction & Workmanship

  1. Stitching Quality:
    • Check stitch density (SPI – stitches per inch)
    • Verify thread color matches specification
    • Inspect seam neatness and consistency
    • Check for skipped stitches, loose threads, broken stitches
  2. Seams & Finishing:
    • Inspect seam allowances (宽度)
    • Check seam strength (pull test on sample seams)
    • Verify seam type matches spec (flat-felled, overlock, French)
    • Examine edge finishing (serging, binding, hemming)
  3. Trims & Embellishments:
    • Verify all trims match approved samples:
      • Zippers (brand, color, functionality)
      • Buttons/Snaps (size, color, placement)
      • Labels (care, size, brand – content accuracy)
      • Elastics (width, recovery, placement)
    • Check embroidery/print quality:
      • Registration and placement
      • Color matching
      • Stitch density for embroidery

Step 6: Functionality & Safety

  1. Garment Function Tests:
    • Try on sample garments (or use form) for fit
    • Test all closures: zippers, buttons, snaps, hooks
    • Check pocket placement and functionality
    • Verify ease of movement
  2. Safety Compliance:
    • Check for exposed sharp objects (pins, needles)
    • Verify choking hazard compliance for childrenswear
    • Inspect flammability compliance labels (if required)
    • Check drawstring safety for children’s hoodies

Step 7: Labeling & Packaging

  1. Label Verification:
    • Care Labels: Content accuracy (symbols/wording), permanence
    • Size Labels: Correct placement, size grading accuracy
    • Brand Labels: Correct logos, placement, stitching
    • Country of Origin: Correct as per trade regulations
    • Fiber Content: Accuracy as per test reports
  2. Final Packaging:
    • Check folding/presentation
    • Verify polybag thickness and warning stickers
    • Inspect hanger quality (if applicable)
    • Verify assortment by size/color in master cartons

PHASE 3: TESTING & VERIFICATION

Step 8: On-Site Testing

  1. Perform Quick Tests:
    • Colorfastness Rub Test: Dry and wet crocking test
    • Zipper Test: 50 open-close cycles minimum
    • Button/Snap Pull Test: Verify security
    • Stretch/Recovery Test for knits
  2. Fabric Verification:
    • Verify fabric composition by burn test (if trained)
    • Check fabric weight (GSM) against specification
    • Inspect knitting/weaving consistency

PHASE 4: DOCUMENTATION & REPORTING

Step 9: Defect Recording & Classification

  1. Document All Defects:
    • Record each defect with clear description
    • Take photographic evidence (with measurement scale if needed)
    • Classify each defect: Critical/Major/Minor
    • Tally defects against AQL limits
  2. Prepare Inspection Report:
    • Summary page with Pass/Fail recommendation
    • Detailed defect breakdown with photos
    • Measurement chart with variances noted
    • Quantity verification summary
    • Packaging and labeling assessment

Step 10: Final Verification & Communication

  1. Hold Exit Meeting with Factory:
    • Present preliminary findings
    • Show defect samples
    • Discuss any immediate corrective actions
  2. Issue Final Report:
    • Send comprehensive report within 24 hours
    • Include clear recommendation:
      • PASS: Ship as is
      • PASS WITH CONDITIONS: Minor issues noted but within AQL
      • FAIL – HOLD FOR SORTING: Requires 100% sorting
      • FAIL – HOLD FOR REPAIR: Specific repairs needed
      • FAIL – REJECT: Critical issues, do not ship

PHASE 5: POST-INSPECTION FOLLOW-UP

Step 11: Corrective Action Monitoring

  1. If Failed:
    • Request Corrective Action Plan from factory
    • Schedule re-inspection if required
    • Verify repairs/sorting before shipping approval
  2. Final Shipping Authorization:
    • Provide written release for shipment
    • Verify final packing list against inspection findings
    • Retain inspection report for quality records
