Quality isn’t inspected in.
It’s engineered in.
Every JIUMU order passes 5 stages of quality control — from incoming fabric to the export carton. Built on 15+ years of manufacturing custom hats, jerseys, pants, socks and team bags for teams, schools and brands in 100+ countries.

From raw material to export box
Quality control at JIUMU is not a final checkpoint — it is a system that starts before the first stitch. Fabric is tested before cutting. Samples are approved before bulk. Every production stage is checked against the approved sample, and finished goods are inspected again before packing.
The 5-stage QC system
Five checkpoints between your design and your shipment. Each one is a gate: if a piece doesn’t match the approved standard, it doesn’t move forward.
Material inspection
Fabric weight, color, knit structure and accessories verified against the spec before cutting.
Sample approval
Digital mockup, then a physical sample for color, logo effect, fit and finishing. You approve it in writing.
Inline checks
Stitching, embroidery density, logo placement, sizing and color accuracy checked during production.
Final inspection
Random sampling of finished goods: seams, closures, decoration, measurements — with photos and video for you.
Packaging check
Labels, polybags, hangtags, barcode and carton marks verified before export packing.
What we check, product by product
Different products fail differently. Here is what our inspectors specifically verify on each category.
Hats & Caps
Jerseys & Uniforms
Pants & Bottoms
Socks & Team Bags
The checks behind the checks
Beyond visual inspection, we run physical and functional checks on materials and finished goods so the quality survives the season — not just the photo.
Color fastness
Wash and lightfastness checks on dyed fabrics — team colors stay true after repeated washing and sun exposure.
Shrinkage control
Pre-shrink testing so jerseys and pants keep their fit after laundering, not just on day one.
Embroidery density
Stitch count and tension checked so logos stay crisp and never pull or distort the fabric.
Seam strength
Stress-point seams on jerseys and pants checked for durability through slides, dives and dugout life.
Closure & zipper function
Snaps, straps, buckles, buttons and bag zippers cycled to confirm smooth, reliable function.
Print adhesion
Sublimation, screen print and heat transfer checked so designs stay bonded — no cracking, peeling or fading.
Quality control, on the floor
Material inspection — fabric, color and finish before cutting.
Inline check — seams and stitching at stress points.
Packaging check — labels, barcodes and export cartons.
Fewer returns
Color, size and quality are verified before shipping — not discovered by your players at the first practice.
Consistent reorders
Your spec, colors and approved sample stay on file, so mid-season additions match the original run.
Sample-first risk
Digital mockup and physical sample before bulk means you approve exactly what you’ll receive.
Full transparency
QC photos and video at final inspection — you see the finished order before the cartons ship.
