How far ahead should you book a quality inspection in China?
The booking lead time matters less than the stage of production. Here is how to fit each inspection to the factory’s calendar and your shipping date.
At LPI, the minimum booking lead time is 48 hours, but book as soon as the production date is known. What decides is the production stage: a final inspection only takes place once the order is finished and packed, a date only the factory can confirm.
The minimum lead time and the recommended one
At LPI Quality, an inspection can be booked 48 hours before the date you want, anywhere in Asia. That is a minimum, not a target. The earlier you book, the more choice you have on the date, and the more time the inspector has to prepare: reading your specifications, receiving the sample you approved, drawing up the checklist with you.
In practice the rule is simple: book as soon as the factory gives you a production end date, even an approximate one. You adjust afterwards. Our planning team sets the final date with your supplier and confirms it to you.
The right moment for each inspection
Each inspection matches a stage of manufacturing. It is that stage, not the booking lead time, that sets the date.
| Inspection | When it takes place | When to book it |
|---|---|---|
| Initial Production Check | When 1 to 20% of the goods are produced | As soon as the production start date is confirmed |
| During Production Inspection | During manufacturing, at around 15 to 20% completion | With the initial production check, or as soon as production starts |
| Production Monitoring | Throughout production, with a daily report | Before production starts: the inspector stays on site for several days |
| Final Random Inspection | Production finished and goods packed | As soon as the factory announces the production end date |
| Container Loading Supervision | On the day the container is loaded | As soon as the loading date is fixed with the forwarder |
The final random inspection is the most common, and the one that slips most often: suppliers readily announce an optimistic production end date. Ask for a firm date one to two weeks ahead, then confirm it a few days before the inspection.
Fitting the inspection to your shipping calendar
Leave a margin between the end of production and the container’s departure. The illustrated inspection report reaches you within 24 hours: you then decide whether to ship, have the goods reworked or sorted, or have them re-inspected. If the lot fails, sorting or rework takes time, then a re-inspection, which also needs at least 48 hours’ notice.
An inspection scheduled the day before the container cut-off therefore leaves you one choice: ship anyway. Place it a few days earlier instead, so you keep the option to act. Our guide failed inspection: what to do details the options and their timing.
The periods to plan for
Some times of year disrupt factory and inspector schedules:
- Chinese New Year (late January or February depending on the year): most factories close for one to several weeks, and production slows before and after, while workers who went home return. Orders due to ship just before the closure jostle for slots: book January inspections in December. Our guide Chinese New Year: orders and inspections gives the backwards calendar.
- National Day (“Golden Week”, 1 to 7 October) and Labour Day (early May): several public holidays during which many factories stop.
- The peak season: from summer to autumn, factories produce for the year-end holidays in Europe and the United States. Production end dates slip more often, and inspection requests pour in.
- Outside China: Tết in Vietnam falls at the same time as Chinese New Year, and Diwali (October or November) slows factories in India.
What to prepare when you book
A complete booking saves everyone time. Prepare:
- the product, the factory address, the quantity ordered and the date you want;
- your specifications: purchase order, technical sheets, drawings, photos, expected markings and packaging;
- the AQL levels agreed with the supplier (our AQL guide and simulator help you choose them);
- the list of possible defects and the tests to run on site;
- ideally, a sample you have approved, sent in advance.
You can send everything through the contact form or from your online account. To see where each inspection fits in the control of an order, read our complete guide to quality control in China.
Frequently asked questions
Can I book without knowing the exact production end date?
Yes, and it is even advisable. Book with an estimated date: our planning team coordinates with your supplier and confirms the final date. Booking early also leaves time to send the approved sample and prepare the checklist.
What happens if the factory is not ready on the planned day?
A final inspection is only valid on a finished order: checking a half-produced lot says nothing about the rest. If the factory announces a delay, tell us right away so we can move the date. That is why the date is set with the factory rather than imposed by the buyer.
Should I inspect before paying the balance?
Yes. The final random inspection must take place before the balance is paid: it is your last chance to get rework without negotiating remotely. Write it into your payment terms, for example “balance payable after a passed inspection”.
