Classification of defective products

The label of defective products is used on defective products, and the manufacturing industry will encounter the problem of defective products, but different industries involved have different requirements for the use of defective products. Such as electronics industry, clothing and textiles, luggage and so on. The labels used for defective products are quite different.
