Quality control · China

Check the goods, not just the factory — $268 per man-day

A verification report tells you who the supplier is. An audit tells you whether the factory is real. Quality control tells you whether the goods you paid for are actually being made correctly — and whether they should be allowed onto the container. Our inspectors work to ANSI/ASQ Z1.4 (AQL) sampling, photograph every defect, and send you a full report within 24 hours of leaving the site. $268 per man-day, all-inclusive: no travel charge, no weekend surcharge.

  • Same all-inclusive man-day rate as the largest inspection firms in Asia
  • AQL General Level II by default — or your own sampling plan
  • Report with photos within 24 hours, in time to hold the payment
Five ways we check an order

From first article to sealed container

Pick the moment in the order where a problem would cost you the most. Most buyers use a during-production inspection on a first order and a pre-shipment inspection on every order after that. If the order is small or the factory is far away, ship the samples to our Zhuhai office instead.

Pre-Shipment Inspection (PSI)

Run when production is 100% complete and at least 80% packed. Random AQL sampling from the finished lot: quantity, workmanship, function tests, measurements, packing and shipping marks. This is the check that decides whether you release the balance payment.

During-Production Inspection (DPI)

Run when roughly 20–60% of the order is finished. Catches a systemic defect while there is still time and material to fix it, instead of discovering it when the whole lot is boxed.

Production Monitoring

Our inspector stays on the line for consecutive days, watching the process rather than sampling the output: raw materials, semi-finished parts, workmanship, output rate and daily corrective-action reports sent to you each evening.

Container Loading Check (CLC)

We're there while the container is loaded: cartons counted, condition verified, loading sequence and stowage photographed, seal number recorded. Stops short shipments and swapped pallets at the last possible moment.

Office Sample Check (Zhuhai)

No inspector travels. The factory ships a percentage of the batch to our Zhuhai office and we check it on the bench: workmanship, measurements, function, labelling and packing, photographed defect by defect. Cheaper than a site visit, and the goods stay in China if you reject them. Price it yourself with the calculator below.

What gets checked

The standard checklist on every inspection

We use ANSI/ASQ Z1.4-2008 (AQL) as the sampling standard, General Level II by default, with Major 2.5 / Minor 4.0 acceptance unless you specify otherwise. Tailor-made checking plans are welcome — send your spec sheet or approved sample and we'll inspect against it.

  • Quantity and assortment against the PO
  • Product appearance and workmanship
  • On-site function and performance tests
  • Materials, accessories and assembly
  • Colours, logo, size, measurements and weight
  • Carton drop test, barcode scan and packing
  • Shipping marks, labelling and warehouse condition
  • Photos of every defect found, with AQL results
How it works

Booked in a day, reported in 24 hours

01

Send the order details

Supplier, product, order quantity, ship date and any spec sheet or approved sample. We confirm the man-days needed and the fixed price.

02

We book with the factory

We contact the supplier directly in Chinese, agree the date, and confirm the goods will genuinely be ready — the most common cause of a wasted inspection day.

03

Inspection day

Our inspector pulls random samples, runs the checks and tests, photographs every defect, and gives you a pass / fail / pending call on site.

04

Report within 24 hours

Full photo report with AQL results in your inbox, plus a short call if the result is a fail so you can decide on rework, discount, or holding the payment.

Pricing

$268 per man-day, all-inclusive

One rate for every inspection type. No travel charge, no weekend or public-holiday surcharge, and free advice before and after the inspection. Most orders need a single man-day; large or multi-SKU orders need more, and we tell you how many before you pay.

During-production inspection$268
  • Per man-day, all-inclusive
  • Run at 20–60% production
  • AQL sampling of finished output
  • Photo report within 24 hours
Book a DPI
Monitoring / loading check$268
  • Per man-day, all-inclusive
  • Production monitoring, day by day
  • Container loading supervision
  • Daily corrective-action reports
Discuss scope

Included in the rate: travel to any major manufacturing cluster in China, weekend and holiday inspections, and consultancy before and after. Inspections are paid before the inspection date. If the factory tells us the goods are ready and they are not, the man-day is spent and charged — we'll always help you re-charge that to the supplier.

New — cheaper than a site visit

Office sample check in Zhuhai

Instead of sending an inspector to the factory, the supplier ships part of the batch to our office in Zhuhai and we check it on the bench. You choose how much of the order gets checked — 2%, 10%, or every single unit — and we give you a clear approve / reject call on the batch before the balance payment leaves your account.

How it works

You tell us the quantity and the percentage you want checked. We send the supplier the shipping instructions in Chinese, receive and log the cartons, check every sampled unit, and email a photo report with an approve / reject recommendation. Domestic freight to us is usually a few dollars and normally billed to the supplier.

What we check

Workmanship and appearance, measurements against your spec, materials and accessories, colour and logo, labelling, barcodes, retail packing, carton drop test, and basic function or power-on tests where the product allows it.

When to use it

Small or high-value orders, samples before mass production, a factory outside Guangdong where travel would dominate the cost, or a repeat order where you only need spot confirmation that quality hasn't drifted.

What it can't do

It can't verify quantities in the warehouse, watch the production line, or supervise loading. If the batch is bulky, heavy, or you need the whole lot counted, a $268 on-site inspection is the right tool — the calculator tells you when.

    Questions

    Quality control FAQ

    How much does a pre-shipment inspection in China cost?

    $268 per man-day, all-inclusive — the same published rate as the largest inspection firms in Asia. Travel, weekend visits and pre/post-inspection advice are included. Most single-SKU orders are one man-day.

    How many man-days does my order need?

    It depends on order quantity, number of SKUs and how much function testing is required. A typical order of a few thousand units in one SKU is one man-day. Tell us the quantity and product and we'll confirm before you pay.

    What sampling standard do you use?

    ANSI/ASQ Z1.4-2008 (AQL), General Level II by default, with Major 2.5 and Minor 4.0. You can specify a different level, tighter AQLs, or a fully tailor-made checking plan.

    When should I book a during-production inspection?

    When about 20–60% of the order is finished. Early enough that a systemic defect can still be corrected on the line, late enough that there is real output to sample.

    How quickly do I get the report?

    Within 24 hours of the inspector leaving the factory, with photos of every defect and a clear pass, fail or pending result. Production monitoring gets a short report every evening.

    Do you inspect outside Guangdong?

    Yes — anywhere in mainland China, at the same $268 per man-day with no travel charge added.

    Can I combine this with a factory audit?

    Yes, and it's the cheapest sequence: $129 desk verification before you pay a deposit, a $398 audit before a first large order, then $268 inspections on each shipment.

    Where quality control fits

    Pre-shipment inspection vs factory audit

    Two different tools at two different moments in the order — which one you actually need.

    On-site factory audit — $398/man-day

    Before the order: machinery, capacity, QC systems and certificates verified in person.

    Supplier verification — $129

    Before the deposit: licence, court records, tax rating and factory-vs-trader status.
