India will not test textiles and textile articles originating from specific countries for the presence of azo dyes, says DGFT. The relevant countries are: Serbia, Poland, Denmark and China. These countries have banned the use of azo dyes in textiles and textile articles. India bans the import of textile and textile articles which contain specified hazardous dyes. Import consignments should be accompanied by a pre-shipment certificate from a textile testing laboratory accredited to the National Accreditation Agency of the country of origin.

In cases where such certificates are not available, the consignment will be cleared after getting a sample of the imported consignment tested and certified from an agency like the Textiles Committee of Ministry of Textiles or the Central Silk Technological Research Institute or the Central Silk Board. Azo dyes are a class of synthetic dyes used for coloring a variety of consumer goods such as foods, cosmetics, carpets, clothes, leather and textiles.

When certain azo dyes have prolonged contact with skin they can break down to form aromatic amines, some of which are known carcinogens. A carcinogen is a substance capable of causing cancer. Although banned in Europe, and restricted in the US, azo dyes are allowed in Australia.
