What quality control points matter most for custom work jacket bulk orders?

For custom work jacket bulk orders, the most important quality control points include fabric durability, seam strength, pocket reinforcement, zipper or button function, lining quality, cuff construction, measurement accuracy, and packing consistency. Work jackets usually need stronger construction than fashion-only jackets because buyers expect durability and functional details. Mature brands should confirm bartack positions, pocket load requirements, hardware finish, label placement, and stitching standards before production. During inspection, the manufacturer should check not only appearance, but also function, symmetry, seam security, and consistency with the approved sample.
