Garment Quality Control: What to Check Before Your Bulk Order Ships
Delen
Why Quality Control Saves You Money
Most quality problems in custom manufacturing are discovered too late — after the order has shipped, when fixing them means returns, discounts, or a ruined season. The good news: almost all of them are preventable with a simple four-stage quality control process. Here is how it works and what to check at each stage.
The Four-Stage QC Framework
- Sample approval — the reference your whole order is judged against
- Pre-production sample — the first piece made with bulk materials
- In-line inspection — checks during production
- Final random inspection — before the goods leave the factory
Stage 1: Sample Approval
Your approved sample is the single most important quality document you own. Before approving, check:
- Fit and measurements against your size chart
- Workmanship — seams, hems, buttonholes, embroidery, print registration
- Fabric hand feel and drape — how it behaves on the body
- Trims and hardware — zippers, buttons, drawcords
Keep one approved sample aside as your reference for production. Both you and the factory should be able to point to the same physical piece.
Stage 2: The Pre-Production Sample
Bulk fabric can behave differently from sample fabric. A pre-production (PP) sample is made with the actual bulk materials and confirmed before cutting starts. This is where fabric shrinkage, color differences, and print placement issues surface — cheap to fix now, expensive after 500 pieces are cut.
Stage 3: In-Line Inspection
Mid-production checks catch problems while they can still be corrected. Ask your factory (or a third-party inspector) to check during production:
- Measurement consistency across pieces
- Stitching quality — tension, skipped stitches, loose threads
- Fabric defects — shading, holes, pulls
- Print and embroidery quality on the actual production run
Stage 4: Final Random Inspection
Before shipment, a random sample of finished pieces is inspected against your approved sample and size specs — this is the standard AQL (Acceptable Quality Limit) approach used across the garment industry. Check that quantities, packing, and labels match your order, and that the goods match the approved reference.
How to Work With Your Factory on QC
- Put standards in writing — size specs, defect tolerances, packaging requirements — before production starts
- Send photo checklists — reference images of stitching, hems, and details you care about
- Ask for progress photos — most serious factories will happily share in-line photos
- Use the same approved sample as the reference for every inspection round
A Note on Choosing a Factory
Transparency about QC is itself a signal of a good factory. A manufacturer that walks you through their inspection process and welcomes your checks is usually one that passes them. The opposite — vague answers about quality — is a red flag. See our full list of questions to ask before you commit to a manufacturer.
