About HS Code 390220
This code covers polyisobutylene (PIB) in primary forms, typically traded as pellets, bales, or viscous liquids. PIB is a synthetic rubber-like polymer known for its exceptional impermeability to gases, flexibility, chemical inertness, and resistance to aging. These unique properties make it invaluable in specialized applications. It is widely used in the production of chewing gum bases, sealants, adhesives, lubricants, and as a key component in tire inner liners and pharmaceutical stoppers. Major importers and exporters include chemical manufacturers, tire companies, and specialized adhesive/sealant producers. The trade in PIB is driven by demand for high-performance materials in niche markets. Understanding its molecular weight (low, medium, high) is crucial, as it dictates its viscosity and end-use applications.
