Categories of Defects

Defects are categorised under three main areas

Critical defect: A defect which makes the garment unsafe for individual consumption or it contravenes any mandatory regulations

Major defect: An obvious defect in the appearance which reduces the usability and sale ability of the garment

Minor defect: A defect which is caused by a workmanship error beyond the quality standards but does not reduce the sale or consumption of the product
