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

Most third-party agencies charge $200–$350 per man-day for a single factory location in eastern China, with a typical drinkware inspection (up to ~2,000 units) completing in one day. Add $80–$150 per sample if you want a separate lab XRF test for steel grade verification. Budget roughly $300–$500 total for a standard PSI.

Can I do a PSI on a small order of 500–1,000 units?

Yes. Most agencies have no order-size minimum — you pay the per-day rate regardless of quantity. For very small orders the inspection cost represents a larger share of order value, but the risk of receiving defective goods is proportionally just as high. Consider a virtual or desktop review (photos and video from the factory) as a lower-cost alternative if budget is tight.

Will the factory allow a third-party inspector on-site?

Reputable factories accept third-party inspection as standard practice — it is a normal part of exporting to Western markets. A factory that refuses or creates obstacles for an independent inspector is a significant red flag. You can include PSI access as a contract term in your purchase order before placing the order.

What AQL level should I use for insulated water bottles?

A common starting point for drinkware is AQL 1.5 for Critical defects (food-contact safety, major structural failure), AQL 2.5 for Major defects (leaks, insulation failure, serious cosmetic issues) and AQL 4.0 for Minor defects (small cosmetic blemishes, minor packaging issues). Define your defect categories in writing before briefing the inspector to avoid ambiguity.

Is a PSI enough to verify 304 stainless steel, or do I need a lab test?

A PSI inspector can flag warning signs — unusual magnetism, surface rust, abnormal weight — but cannot conclusively verify steel grade in the field. For confident 304 verification, request a separate XRF spectrometry test from an accredited lab. This costs $80–$150 per sample and is the only reliable field-accessible method to detect 201 substitution.
