About HS Code 291736

Terephthalic acid (TPA) and its salts are fundamental building blocks in the chemical industry, with international trade dominated by purified terephthalic acid (PTA). PTA is overwhelmingly used in the production of polyethylene terephthalate (PET) resin, which is essential for plastic bottles, polyester fibers for textiles, and packaging films. Major importers are countries with large textile and beverage industries, such as China, India, and various Southeast Asian nations. Exporters are typically large-scale petrochemical producers, often in Asia and the Middle East. Key factors influencing trade include global demand for PET products, crude oil prices affecting production costs, and the critical importance of high purity for end-use applications. Its market is highly integrated with the global plastics and textile value chains.
