Pre-shipment inspection in China: what it costs and what to check
How third-party pre-shipment inspection works for packaging orders made in China, what it costs (about $330–$750 per visit), and the checklist we use for boxes and clamshells.
A pre-shipment inspection is the last chance to catch problems while your packaging is still at the factory — and while you still hold the final payment. Here's how it works, what it costs and what we check on boxes and clamshells.
How it works
- Production reaches roughly 80–100% complete and packed.
- An independent inspector visits the factory (no notice to the line workers about which cartons get pulled).
- Random samples are pulled using a standard sampling plan (AQL) and checked against your approved sample and spec.
- You get a photo report the same or next day: pass, fail or hold with the issues listed.
- Only after a pass (or fixes and re-inspection) is the balance paid and the goods shipped.
What it costs
Across the inspections on our packaging orders, a standard pre-shipment inspection ran about $330 per visit, double inspections around $660, and a factory audit around $750. On an order of 50,000 boxes, that's well under a penny per piece.
What we check on rigid and magnetic boxes
- Print color vs. the approved proof; registration and scuffing
- Magnet strength, lid alignment and closure
- Wrap adhesion, corners, bubbling
- Insert fit with the actual product
- Dimensions, master carton strength, counts and shipping marks
What we check on clamshells and blisters
- Material clarity and thickness (cloudy or thin spots)
- Cracks or stress whitening at hinges and corners
- Fit with the product and closure strength
- Trimming, sharp edges and flash
- Nesting, carton counts and carton marks
Real-world catches
"Hold" results are more common than outright fails. On our orders, inspectors have flagged missing shipping-mark specifications, carton sizes that didn't match the printed marks, and finish issues on magnetic boxes — all fixed before the goods left, instead of being discovered at the warehouse.
Tip: give the inspector your approved physical sample (or a golden sample kept at the factory) and a written spec. Inspectors can only check against what they're told.
Inspection is built into how we work
Every production order we manage gets a third-party inspection before the balance is paid. See how we work or get a free landed quote for your packaging.
Frequently asked questions
How much does a pre-shipment inspection cost in China?
Typically about $330–$750 per inspection visit (one inspector-day is the common unit). Factory audits and multi-day inspections cost more.
When should the inspection happen?
When production is at least 80% complete and packed, so the inspector can pull random samples from finished cartons — and before you pay the final balance.
What happens if an inspection fails?
The factory reworks or replaces the defective goods and a re-inspection is booked. Because the balance is paid only after a pass, the factory has every incentive to fix it.
Is inspection worth it on small orders?
On orders under a few thousand dollars it can be proportionally expensive. On five- and six-figure packaging orders it's cheap insurance.
