Epoxides, epoxyalcohols, epoxyphenols and epoxyethers; with a three-membered ring and their halogenated, sulphonated, nitrated or nitrosated derivatives, methyloxirane (propylene oxide)

HS code 291020 covers: Epoxides, epoxyalcohols, epoxyphenols and epoxyethers; with a three-membered ring and their halogenated, sulphonated, nitrated or nitrosated derivatives, methyloxirane (propylene oxide). Methyloxirane, or propylene oxide, is a vital chemical building block extensively traded internationally. It's a colorless, volatile liquid primarily used in the production of polyurethane polyols, which are critical components for foams, coatings, and adhesives in the construction, automotive, and furniture sectors. It also serves as a precursor for propylene glycol, used in cosmetics, food, and pharmaceuticals. Large petrochemical corporations such as LyondellBasell, Dow, and SKC dominate its global supply chain. Importers are typically manufacturers requiring intermediates for polymer production or specialty chemicals. Its flammability and reactivity necessitate stringent handling and transportation protocols in global commerce.

Often confused with other epoxides like ethylene oxide (2910.10) due to similar chemical classification, but its methyl group makes it chemically distinct and leads to different end-use applications.

HS code 291020 is a 6-digit subheading under the Harmonized System. The first 2 digits (29) identify the chapter, digits 3-4 (10) identify the heading, and digits 5-6 (20) specify the subheading. This code is standardized globally by the World Customs Organization.
