About HS Code 291735

Phthalic anhydride is a crucial chemical intermediate traded globally, primarily serving as a precursor for plasticizers used in PVC, unsaturated polyester resins (UPR), and alkyd resins for paints and coatings. Its international trade is driven by the construction, automotive, and packaging industries. Countries with extensive manufacturing capabilities for plastics and paints, such as China, India, and various European nations, are major importers. Exporters are typically large-scale petrochemical producers. Key considerations for trade include its physical form (flakes or molten), purity specifications, and compliance with environmental and safety regulations, as it is classified as a hazardous substance. Global demand is closely tied to economic growth and industrial production cycles.
