Terephthalic acid is an organic chemical that is a member of the aromatic carboxylic acid family. Its lightweight lightness and moisture resistance make it a popular material for a variety of packaging applications, such as bottles for beverages, food, and personal care goods. Its acid-based polymers are used to make films and sheets for use in packaging, electrical displays, and solar panels.

To ensure the product quality of terephthalic acid, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to undergo BIS registration and obtain the BIS ISI mark before selling it in the market. Manufacturers can use the ISI Mark on their products only after obtaining a license from BIS that is granted after BIS registration. The presence of the ISI mark on a product indicates that it complies with BIS's stringent quality standards.

IS 15030:2001 covers Terephthalic acid. The Bureau of Indian Standards adopted this Indian Standard after the Petroleum, Coal, and Related Products Division Council approved the draft finalized by the Organic Chemicals Sectional Committee.

This standard specifies the requirements and sampling and testing methods for pure terephthalic acid. Terephthalic acid is produced by oxidizing para-xylene, and it is also known as para phthalic acid, benzene para dicarboxylic acid, or 1,4 benzene dicarboxylic acid in the commercial world. By combining with glycols, it is used in the production of synthetic resins, fibres, and films.
