Quality Control
Pre-shipment inspection 101 — stop bad reviews before they ship
AQL sampling, HD photo reports, and rework workflows for brands that never touch the carton in China.
Shipping blind is the fastest way to turn a five-star brand into a chargeback machine. Pre-shipment inspection (PSI) is your last defensible gate before goods leave China.
The PSI workflow
- AQL sampling — statistical or 100% inspection based on SKU risk and order value.
- Functional testing — power-on, dimension checks, and packaging drop tests where relevant.
- Cosmetic grading — surface defects sorted against your accept/reject matrix.
- HD evidence — timestamped photos and video clips tied to carton IDs.
- Hold / release — nothing ships until you approve the report in writing.
Defect sorting and rework
When issues appear, Tendlyn coordinates sorting, rework, or partial shipment—so you choose whether to absorb delay or protect your review score.
Who needs PSI most
- D2C brands with no China presence
- Amazon sellers running hybrid FBA + direct ship
- Subscription boxes where one bad unboxing kills LTV
