China Inspection Services

Inspection services for Amazon FBA sellers and ecommerce importers.

QIS helps overseas buyers verify product quality, supplier reliability, Amazon FBA shipment readiness and loading evidence before goods leave China.

Product Inspections

Pre-Shipment Inspection in China

Pre-shipment inspection is the final quality checkpoint before goods are released for final payment, freight pickup or Amazon FBA delivery. QIS inspects finished products using agreed AQL sampling and your product checklist.

When to book

Production is 100% finished and at least 80% packed.
You need a decision before paying the supplier balance.
Goods will ship to Amazon FBA, a freight forwarder or your warehouse.

What QIS checks

Quantity, assortment, carton count and packing list consistency.
Workmanship, appearance, function, size, color and accessories.
Retail packaging, barcode, FNSKU, carton labels and shipping marks.
Critical, major and minor defects under agreed AQL levels.

Report output

Pass, fail or hold-shipment recommendation.
Photo evidence of checked samples and defects.
AQL result, sample size, defect list and shipment remarks.

Factory & Supplier Audits

Factory Audit and Supplier Verification

Factory audit helps buyers understand whether a supplier is real, capable and suitable before paying a deposit, placing a trial order or expanding order volume.

When to book

You are working with a new supplier in China.
The order value is high or supplier risk is unclear.
You need evidence before deposit or larger purchase order.

What QIS checks

Business identity, factory address and production site.
Production capacity, equipment, workforce and process flow.
Incoming material control, in-process checks and final QC.
Basic compliance, sample room, warehouse and shipment control.

Report output

Supplier risk summary and factory capability notes.
Photos of site, equipment, production line and documents.
Practical recommendation before moving forward.

Production Control

During Production Inspection

During production inspection checks goods while the order is still being made. It helps catch quality issues early enough for the supplier to correct them before the full batch is completed.

When to book

20% to 80% of the order is already produced.
You have a new product, new supplier or tight schedule.
Previous orders had repeated defects or late corrections.

What QIS checks

Production progress, finished quantity and packed quantity.
Materials, components, workmanship and early defect trends.
Function, appearance, size, color, labels and packaging status.
Corrective action follow-up on the production line.

Report output

Production status and delay-risk summary.
Defect photos and recommended corrective actions.
Decision support: continue, correct, hold or reinspect.

Quality Engineering

Supplier Quality Control

Supplier quality control is used when one-time inspection is not enough. QIS helps track recurring defects, confirm corrective actions and support repeat-order quality decisions.

When to book

Repeat orders show similar defects or customer complaints.
A previous inspection failed and supplier claims rework is done.
You need ongoing production monitoring instead of one visit.

What QIS checks

Defect trend, root cause and supplier corrective action.
Reworked goods, process changes and quality-control records.
High-risk checkpoints defined by your product and complaint history.

Report output

Corrective action evidence and remaining risk.
Repeat-defect tracking and inspection recommendation.
Support for approve, reinspect or hold-shipment decisions.

Shipment Control

Container Loading Supervision

Loading supervision verifies that the right cartons are loaded into the right container and records shipment evidence before goods leave the factory or warehouse.

When to book

Shipment quantity, mixed SKUs or loading evidence is important.
You need container and seal information before departure.
Goods are shipped directly to Amazon FBA or overseas warehouse.

What QIS checks

Carton count, carton condition and packing list consistency.
Container cleanliness, damage, moisture risk and loading condition.
Loading process, stacking condition, container number and seal number.

Report output

Loading photo record and shipment condition summary.
Carton count confirmation and visible damage notes.
Container number, seal number and final loading evidence.

Buyer risk control

Common sourcing problems QIS helps Amazon and ecommerce sellers prevent.

Most overseas sellers do not only need a generic inspection. They need practical evidence before paying balance, shipping to Amazon FBA, or sending goods to a 3PL warehouse.

Supplier ships before defects are fixed

Use PSI or DPI to document defects, request rework and avoid accepting goods only after they arrive overseas.

Wrong labels or unreadable barcodes

For Amazon-bound orders, QIS can check FNSKU labels, carton labels, barcode readability and packaging warnings before shipment.

Factory is not the real manufacturer

Use supplier verification and factory audit before deposit payment to reduce middleman, fake factory and weak-capacity risk.

Carton quantity does not match documents

Use loading supervision to confirm carton count, container condition, seal number and shipment photo evidence.

Repeat orders keep failing

Use supplier quality control to follow defect trends, corrective action and production monitoring across repeat orders.

Unclear AQL acceptance criteria

Use the QIS AQL calculator and inspection checklist to align sample size, accept point and reject point before inspection day.

Amazon FBA sellers

Amazon FBA inspection is a combined checklist, not only one service.

For Amazon sellers, QIS can add FNSKU labels, carton labels, barcode readability, polybag warning, packaging and shipment readiness checks into PSI, DPI or loading supervision.
