Paying the balance before you've seen the goods is the most expensive habit in importing. A quality inspection puts an independent set of eyes on your order — in the factory, before it ships — so problems are fixed in China while you still hold the leverage of an unpaid balance.

Our inspectors work to your specification and an AQL checklist, then send a same-day report with photos and a clear pass or fail. You decide whether to release payment based on evidence, not promises.

The right fit

Who this is for

This service is for:

  • Importers who pay 30% deposit / 70% balance and want proof before the balance.
  • Buyers of containerized goods — from one full container — who can't inspect in person.
  • Companies that need inspection certificates for customs or resale.
Our process

How a pre-shipment inspection in China works

  1. 1

    Define standards

    We agree the checklist, AQL level, and acceptance criteria.

  2. 2

    On-site inspection

    Our inspector visits the factory and checks the actual goods.

  3. 3

    Function & labeling

    We test function, measurements, labeling, and packaging.

  4. 4

    Photo report

    You get a detailed report with photos within 24–48 hours.

  5. 5

    Go / no-go

    You release the balance only once it passes.

Goods inspection or factory inspection?

People search for both under the same words, and they answer different questions at different moments. A first order of any size usually needs more than one.

Goods inspection

Is this batch correct? Quantity, workmanship, function, labelling and packing, checked against your spec before the goods leave China. This is the page you are on.

Factory inspection

Can this plant make it at all? Lines, equipment, workforce, certifications and capacity — done before you commit, not before you ship. That is supplier verification.

Loading supervision

Did what was inspected actually go into the container? Our inspector watches the load and counts it, which is where substitution and short-shipping get caught.

Critical, major, minor: how defects are actually counted

A pass or fail is not a matter of opinion. Every defect found is sorted into one of three classes, and the AQL limits set how many of each a batch may contain before it fails. Agreeing those classes before production is what stops the argument afterwards.

The classification matters more than the total count: one critical defect can fail a batch that has dozens of acceptable minor ones.

  • Define what counts as critical for your product before production starts
  • Cosmetic tolerances are the most common source of disputes — put them in writing with photos
  • A signed golden sample settles most arguments faster than any specification document
The three defect classes
  • Critical — unsafe, illegal to sell, or certain to be rejected by your customer
  • Major — the product does not work or does not match the agreed spec; a buyer would return it
  • Minor — a cosmetic deviation a buyer would probably accept
  • AQL limits set how many of each class a batch may contain
  • Anything undefined before production becomes a negotiation after it

Types of inspection we run

Different stages catch different problems. We inspect at whichever point — or points — your order needs.

Pre-production (PPI)

Checks raw materials and components before the line starts, so defects don't get built in.

During production (DUPRO)

Catches issues early, while 20–60% is made and there's still time to correct them.

Pre-shipment (PSI)

The standard final check on finished, packed goods before the balance is paid. Most popular.

Container loading (LI)

Verifies the right goods, quantities, and careful loading as the container is filled.

Full / 100% inspection

Piece-by-piece check for high-value or low-tolerance goods, instead of sampling.

What an inspection checks

Every inspection runs against a checklist tied to your spec and an approved sample, so the result is objective — measured against an agreed standard, not the inspector's taste.

We adapt the checklist to your product, but the core always covers form, function, and how it's packed for the journey.

On every inspection
  • Appearance — finish, colour, workmanship against the sample
  • Function & safety — does it work as intended
  • Dimensions and critical parameters
  • Quantity and completeness of the order
  • Accessories, manuals, and packaging contents
  • Retail and carton labelling, barcodes, markings
  • Carton drop test and packaging durability

AQL sampling vs 100% inspection

Two ways to inspect a batch. The right one depends on your order's value and how much defect risk you can carry.

What's in the inspection report

You get the report the same day, usually within hours of the inspector leaving — in time to act before the balance is due.

Defects are classified the way the industry does it, so 'pass' and 'fail' mean something specific, not a judgment call.

Your inspection report
  • Pass / fail against your AQL limits
  • Defects classified critical, major, and minor
  • Measurements vs your tolerances
  • On-site photos and video
  • Quantity and packaging verification
  • Clear recommendation: ship, rework, or hold

Risk & response

Why inspect before the balance payment

The problem we solve — and how we solve it.

Common mistake / risk

Paying the 70% balance before seeing the goods means trusting blind.

How Silk Way handles it

We inspect before the balance, so payment follows proof.

Common mistake / risk

Defects found after shipping are expensive or impossible to fix.

How Silk Way handles it

We catch issues at the factory while they're still fixable.

Common mistake / risk

Wrong labeling or packaging gets goods stuck at customs.

How Silk Way handles it

We verify labeling and packaging against your market's rules.

FAQ

Quality inspection in China: common questions

Do you offer lab testing and factory or social-compliance audits?

Yes, alongside the standard AQL inspection. We arrange third-party laboratory testing (materials, safety, performance, RoHS/REACH and similar) and factory audits — quality-system audits and social-compliance audits to BSCI, Sedex/SMETA or ISO frameworks. These are separate from the on-site AQL check and are booked when your buyer, retailer or import market requires them.

When should the inspection happen?

Most clients book a pre-shipment inspection on finished, packed goods, just before the balance payment. For larger or complex orders, an earlier during-production check catches problems while there's still time to fix them.

What is AQL and which level do you use?

AQL (Acceptable Quality Limit) is the international sampling standard: it sets how many units to check and how many defects allow the batch to pass. We typically use the common AQL 2.5 for major defects, and adjust the level to your product and risk tolerance.

Do you inspect every piece or a sample?

Usually a sample, by AQL rules — fast and statistically sound for standard goods. For high-value or zero-tolerance products we offer 100% (piece-by-piece) inspection instead.

How fast do I get the report?

The same day in most cases, often within a few hours of the inspector leaving the factory — so you can decide on the balance payment without delay.

What do you inspect against?

Your specification plus an approved sample and a checklist agreed in advance. That makes the result objective: the goods either meet the agreed standard or they don't.

What if the goods fail?

You decide with evidence in hand: hold the balance, require rework and re-inspection, or reject the batch. Because it's caught before payment and shipping, the factory has every reason to fix it.

Can you inspect goods from a supplier I found myself?

Yes. We inspect at any factory in China, whether you sourced the supplier through us or independently.

What is the difference between a goods inspection and a factory inspection?

A goods inspection checks the batch you have paid for, against your specification, before it ships. A factory inspection checks whether the plant can make your product at all — lines, equipment, capacity and certifications — and belongs earlier, before you commit. They are different jobs at different moments, and a first order of any size usually needs both.

Can you supervise container loading as well as inspect the goods?

Yes, and on a first order it is worth it. An inspection confirms the batch was right when it was checked; loading supervision confirms that batch is what actually went into the container. Counting and watching the load is where substitution and short-shipping are caught, and it is a short job compared with the value it protects.

How much does an inspection cost?

Pricing isn't fixed — it depends on the complexity, scope, and resources the job needs. Tell us what you're planning and we'll give you a clear quote up front, with no hidden costs.
