Garment Quality Control: How Factories Inspect Before Shipment
How garment quality control works before shipment: three inspection checkpoints, what inspectors check against the approved sample, and how buyers verify it.
A quality problem found after shipment costs ten times more than the same problem caught at the machine. That is the whole argument for garment quality control - and the reason a serious factory inspects three times, not once. Here is what actually happens between 'sewing done' and 'cartons sealed' in our Shenzhen factory.
Three checkpoints, not one
Incoming fabric comes first. Weight, shrinkage behavior, color consistency - checked before a single panel is cut, because a fabric problem multiplies through every piece downstream. This is also where we weigh a cut panel on the scale when a buyer asks us to prove a 240gsm claim.
Inline checks during sewing come second. The first pieces off each line get measured and pulled apart a little - seam allowances, stitch density, bar tacks at stress points. Catching a wrong folder setting at piece one is an adjustment; catching it at piece five hundred is a claim.
Final inspection before packing comes last. Finished garments are checked against the approved pre-production sample - the sample you signed off - not against a memory of it.
What a final inspection actually covers
Measurements against the size chart at the spec points that matter: shoulder, chest, body length, sleeve. Stitching: straight seamlines, even density, the correct stitch type for the fabric - coverstitch on knit hems, chain stitch where stretch matters. Bar tacks present at pocket corners and zipper ends. Buttons tight, buttonholes cleanly cut, zips running smooth without snagging the tape. Labels correct and attached where the tech pack says. And the inside of the garment tidied - trimmed threads, no tangles. A factory that finishes the inside cleanly is disciplined everywhere.
Different fabrics fail differently, so the checklist has to know that. Knit tees get a collar-recovery check: stretch the rib, watch it spring back - a collar that waves after two washes is the loudest cheap signal a tee can send, so we test it before you do. Chiffon dresses get every seam edge checked for overlocking, because chiffon frays hard enough to pull a seam open in the wash. The 240gsm tee and the chiffon maxi in our catalog never see the same defect list.
How buyers verify without being here
Ask the factory what their inspection covers and when it happens - vague answers are the warning sign. Request pre-shipment photos or a short video of packed cartons plus a few loose pieces out of the carton. Welcome a third-party inspection; an honest factory has nothing to hide and will give your inspector a table. And wash-test your approved sample twice before bulk starts, so you know what 'correct' looks like when the shipment arrives.
