The QC Inspection Checklist Every Importer Needs

Quality control is where sourcing profits are won or lost. A product that looks perfect in a sample photo can arrive with the wrong stitching, loose parts, or packaging that fails in transit. The difference between sellers who scale and sellers who drown in refunds is usually a disciplined inspection process.

This checklist covers the four inspections we recommend depending on order size and risk.

1. Pre-Production Inspection (PPI)

Done after raw materials arrive but before mass production begins. The inspector verifies that materials, components, and colors match your approved specifications and golden sample. Catching a wrong fabric or plastic grade here saves the entire production run.

• Verify raw materials against the approved spec sheet.
• Confirm colors against Pantone references under standard lighting.
• Check that tooling and molds are ready and correct.

2. During Production Inspection (DPI / DUPRO)

Done when roughly 20–30% of the order is complete. The inspector checks workmanship on the line and flags systematic defects while there is still time to correct them. For orders over $20,000 or products with complex assembly, this inspection pays for itself many times over.

3. Pre-Shipment Inspection (PSI) — the non-negotiable one

Done when 100% of goods are produced and at least 80% are packed. This is the inspection almost every importer should run on every order. We follow the AQL (Acceptable Quality Limit) sampling standard:

• Quantity verification — is the full order produced and packed?
• Workmanship check on a statistically valid random sample (AQL levels per your tolerance).
• Function and safety testing — does the product actually work as specified?
• Packaging and labeling — barcodes, cartons, shipping marks, and compliance labels.
• Container loading supervision for FCL shipments to prevent damage in transit.

4. Container Loading Check (CLC)

For full container loads, an inspector supervises loading to confirm the right cartons go in, the container is dry and undamaged, and cartons are stacked to survive the voyage. Moisture damage inside containers ruins more shipments than most sellers realize.

What your inspection report should include

Insist on a report with dated photos of defects, measurements against your spec sheet, a clear pass/fail verdict, and the inspector's recommendation. A report that only says "looks good" is worthless. Ours include defect close-ups mapped to AQL tables so you can negotiate rework with evidence.

How to set your AQL

AQL 2.5 for major defects and 4.0 for minor defects is a common starting point for consumer goods. Cosmetic products and electronics usually need tighter levels. Define your defect classification (critical / major / minor) in writing before production starts, and share it with both the factory and your inspector.

The rule is simple: inspect before you pay the balance. Once the final payment leaves your account, your leverage over rework disappears.
