In the garment industry, whether you are a manufacturer, importer, or brand, you must understand the importance of quality control in this business. This industry shifts swiftly, and any time lost in shipment or defect fixings can lead to unimaginable losses. Moreover, quality issues can quickly disseminate in the digital age, giving competitors an advantage. Therefore, quality control is essential, and quality inspection is the most commonly used method. In this post, we will guide you through the steps of a garment quality inspection, the key checkpoints to focus on, and how can C&Z expertise support your garment quality control.
