Quality inspection.

Three inspection points along the production cycle so defects get caught when they're cheap to fix — before goods leave the factory, not after they land in your warehouse.

Why QC Matters / 001

The cost of skipping QC compounds at every step.

A defect found on the factory floor costs cents to fix. The same defect found in your Amazon FBA warehouse costs you returns, refunds, ratings damage, and re-shipping fees — often 50–100× more.

Quality Inspection is the single highest-ROI service we offer, and the one we recommend for every order, regardless of factory.

Real cost of one defective unit found late
  • Cost at factory: $0.10 rework
  • Cost at QC station: $0.50 rework
  • Cost at U.S. warehouse: $8 inspect + return-to-vendor freight
  • Cost on Amazon: $25–80 refund + return + restocking + rating hit
Three Stages / 003

Catch problems at every stage — not just at the end.

Each inspection serves a different purpose. Many buyers use all three for high-stakes orders.

PPI · Pre-Production

Before production starts

Verify raw materials, components, and tooling match the approved specification — before the factory builds a single unit.

  • Raw material check
  • Component verification
  • Tooling & mold inspection
  • Golden sample sign-off
DUPRO · During-Production

When 20–60% complete

Catch process drift mid-run. Identify systematic defects before they propagate across the whole order.

  • Workmanship check on completed units
  • Process & equipment verification
  • Early defect-pattern detection
  • Course-correction with factory
PSI · Pre-Shipment

Before goods leave the factory

The non-negotiable one. AQL-based statistical sampling of finished, packed goods — your last line of defense.

  • Workmanship & function tests
  • Dimensions, weight, color
  • Packaging, labeling, barcodes
  • Carton drop & container loading checks
AQL Explained / ISO 2859

Acceptable Quality Limit — the standard we inspect against.

AQL is the international statistical framework (ISO 2859) for accept/reject decisions on a production batch. Here's how we apply it.

CriticalAQL 0
RejectAny defect that creates a safety hazard or violates regulations. Zero tolerance — even one critical defect rejects the entire batch.
MajorAQL 2.5
LimitedDefects that affect function or appearance noticeably. Our default standard — allows up to 2.5% by sample.
MinorAQL 4.0
ToleratedCosmetic issues unlikely to affect function or customer satisfaction. Allows up to 4.0% by sample.

Custom AQL levels available. For Amazon FBA sellers we often recommend Major 1.5 / Minor 2.5 — tighter than industry standard, because Amazon ratings amplify defect impact.

What We Check / 006 Dimensions

Every PSI covers these dimensions.

Workmanship

Stitching, welding, joints, finish. Looks-vs-spec compliance.

Function

Does it actually work? Power-on, switches, controls, electronics tests.

Dimensions & Weight

Measured against the approved tech pack with tolerance ranges.

Color & Material

Pantone match check, material composition, fabric weight.

Packaging & Labeling

Inner box, master carton, barcodes, FBA labels, country-of-origin.

Carton & Container

Carton drop test, container loading photos, weight/volume verification.

The Report / 001

You get a detailed PDF report within 24 hours.

Photo and video evidence of every defect, AQL pass/fail decision, and a clear recommendation: accept, conditional-accept-with-rework, or reject.

  • 20–40 page PDF with photos of every defect class
  • Video walkthrough of the inspection
  • Container loading photos
  • Final AQL decision with reasoning
  • Recommended next step

When Things Go Wrong / 004

What happens if goods fail QC?

Failing inspection is not the end — it's the point where you avoid the much bigger cost of a bad shipment.

Step 01

Hold the shipment

Goods don't leave the factory. The deposit and your downstream commitments are protected.

Step 02

Document the defects

Photo/video evidence delivered to factory and you, with proposed remediation.

Step 03

Rework, replace, or refund

We negotiate the path forward — rework defective units, replace the batch, or partial refund. You decide, we execute.

Step 04

Re-inspect

After rework, we re-inspect at no extra charge until the batch passes — or you walk away.

Q&A / 005

Quality inspection questions.

How much does an inspection cost?
For most goods, $250–$400 per inspection day, plus travel. We quote each project upfront. A typical PSI on 5,000 units takes one full day.
Can I get QC even if Verity didn't source the factory?
Yes. We offer inspection as an à la carte service. You give us the factory address, PO details, and inspection date — we handle the rest.
What's the difference between AQL 1.0, 2.5, and 4.0?
AQL is the maximum % of defective units the buyer will accept. Lower number = stricter. AQL 1.0 is for safety-critical items, 2.5 is standard consumer goods, 4.0 is loose tolerance (rarely used).
Do inspectors speak English?
All reports are in English. Inspectors on-site work in overseas with factories and translate findings to your account manager in real time.
Can I attend the inspection remotely?
Yes. We offer live video walkthroughs via Zoom or Google Meet at no extra charge. Useful for first-time orders or unfamiliar products.
