Why 100% Pre-Shipment Inspection Matters (And How We Do It)

How thorough pre-shipment inspection ensures consistent quality for your knitwear orders before they leave the factory.

By Felix Zheng

Most factories perform random sampling inspection (AQL), checking only a percentage of garments. But at JIERQI Clothing, every single garment undergoes visual inspection before packing. Here is why this matters and how we do it. This article explains the inspection process and how it protects your brand.

The Difference Between AQL and 100% Inspection

AQL Sampling (Industry Standard)

  • Inspects 20-200 pieces depending on batch size
  • Accepts up to 2.5% defect rate
  • Faster and cheaper per order
  • Risk: defective pieces can reach your customers

100% Visual Inspection (Our Standard)

  • Every single garment checked
  • Zero tolerance for visible defects
  • More time and labor intensive
  • Result: consistent, defect-free shipments

What We Check on Every Garment

Visual Inspection (100%)

For each garment, our QC team checks:

  1. Overall appearance: Shape, drape, finishing
  2. Stitch quality: No dropped stitches, consistent tension
  3. Seam finishing: Linking quality, no gaps or puckering
  4. Color consistency: Against approved sample
  5. Cleaning: No loose threads, oil stains, or marks
  6. Trims: Buttons, zippers, labels correctly attached
  7. Packing: Correct folding, polybag, carton packing

Measurement Verification (AQL Sample)

We also verify measurements on a random sample:

  • Body length, sleeve length, shoulder width
  • Chest/bust circumference
  • Hem and cuff dimensions
  • Against approved sample and spec sheet

Our Inspection Process

Stage 1: In-Line Inspection

Our QC team visits partner factories during production to catch issues early. This prevents defective batches from reaching the finishing stage.

Stage 2: First Piece Approval

The first finished piece from each production run is checked against the approved sample before bulk production continues.

Stage 3: Pre-Shipment Inspection

Once production is complete:

  1. Garments are laid flat on inspection tables
  2. Each piece is visually inspected front and back
  3. Measurements verified on AQL sample
  4. Defective pieces are tagged and separated
  5. Passed pieces proceed to packing

Stage 4: Packing Inspection

Random inspection of packed cartons:

  • Correct quantity per carton
  • Proper folding and polybagging
  • Shipping marks and labels correct
  • Carton condition

The Cost of Skipping Inspection

Skipping or reducing inspection can lead to:

  • Customer returns and exchanges
  • Brand reputation damage
  • Expedited shipping costs for replacements
  • Lost future business

How to Request Inspection Reports

We document all inspections and can provide:

  • Per-order inspection reports
  • Photographs of inspected garments
  • Measurement reports
  • Defect rate analysis

Quality is our commitment. Contact us to discuss inspection requirements for your orders.
