Your Trusted China Supplier Auditor
One bad batch doesn't just cost you money.
It costs you your ranking.
Your Amazon listing took months to build. A single defective shipment — or an FBA compliance rejection — can collapse it in days. We verify your Chinese suppliers before the goods ever leave the factory.
Amazon's rules have no mercy for bad suppliers.
The platform doesn't care that your factory sent defective goods, mislabeled the cartons, or couldn't hold quality across the full production run. You bear the consequences — returns, suppressed listings, seller account warnings, and lost Buy Box position.
"Sample ≠ Production"
The sample the factory sends you is often handmade by their best worker with their best materials. Mass production uses a different process — and different quality controls.
FBA Compliance Is Unforgiving
Wrong barcode placement. Wrong poly bag thickness. Wrong label format. FBA will reject your entire shipment — and you pay the return freight.
Batch Inconsistency Kills Listings
Your first order was great. Your third order had a 12% defect rate. One wave of 1-star reviews is enough to suppress your BSR and trigger Amazon's quality alert systems.
Trading Companies Masquerading as Factories
If your "factory" is actually a trading company, you have no visibility or control over the real manufacturer — and zero leverage when quality fails.
You've heard these before. Or lived them.
The sample was perfect. But when 800 units arrived at FBA, the material was noticeably cheaper. I had no leverage — goods were already in the warehouse.
FBA rejected my entire pallet. The factory printed the FNSKU in the wrong position. I paid $1,200 in return freight on a $6,000 order.
My supplier started subcontracting to a smaller factory after my third order. I only found out because the defect rate jumped to 18%. My listing dropped 40 positions.
Every checkpoint that stands between you and a listing catastrophe.
We don't inspect products in isolation. We verify the supplier, the production process, and the shipment — end to end — through a financial-grade lens that standard inspection firms don't apply.
-
Background Check
Verify the factory is a real manufacturer (not a trading company), confirm legal entity status, flag corporate anomalies and litigation history.
-
Sample Acceptance & Review
Inspect the sample against your spec sheet before you approve it. Confirm materials, dimensions, finish, and labeling.
-
Pre-Order Inspection
On-site factory visit to assess real production capacity, equipment condition, and workforce stability before you commit your order.

In-Progress QC (DUPRO)
Mid-production visit at 30–50% completion to catch material substitutions, subcontracting, and defect trends before they reach every unit.
-
Pre-Shipment Assurance (PSI)
Full AQL sampling inspection on 100% produced, packaged goods. Defect rate, quantity, and compliance verified before balance payment.
-
FBA Packaging & Labeling Compliance
Barcode placement, FNSKU format, poly bag thickness, suffocation warning labels, carton dimensions and weight — every FBA prep standard checked.
-
Compliance Document Verification
Cross-check your CE, FCC, or other certificates against the actual goods being shipped — not a previous model or batch.

Stop hoping the factory did it right. Know.
Most Amazon sellers discover supplier problems at the worst possible moment — when goods arrive at FBA, when reviews start dropping, or when Amazon sends a policy warning. By then, the leverage is gone.
Our package gives you verified answers at every stage of the sourcing process, so you can sell with confidence instead of crossing your fingers.
"SourcInspecify's pre-shipment report caught a barcode placement issue that would have triggered FBA rejection on my entire shipment — 640 units. The factory fixed it in 2 days. At $399, it was the best money I spent that quarter."
Your listing is only as strong as your last shipment.
Verify before you ship. Every time.
