About HS Code 290920
This HS code covers cyclanic, cyclenic, or cycloterpenic ethers and their halogenated, sulphonated, nitrated, or nitrosated derivatives. These cyclic ethers are distinct from their acyclic counterparts due to their ring structures, which impart unique chemical properties. They are widely utilized as specialty solvents in various industrial applications, including pharmaceuticals, agrochemicals, and polymer synthesis. Tetrahydrofuran (THF) is a prominent example, known for its excellent solvent properties for PVC and in Grignard reactions. Trade in these compounds often involves fine chemical companies, research and development-intensive industries, and manufacturers requiring specific, high-performance solvents or intermediates. Their higher value often reflects the complexity of their synthesis and specialized applications.
Products Under This Code
Tetrahydrofuran (THF), 1,4-Dioxane, Tetrahydropyran, Furan, Dihydropyran, Cyclohexyl methyl ether, 2-Methyltetrahydrofuran
Real World Examples
BASF Tetrahydrofuran, Sigma-Aldrich 1,4-Dioxane, TCI America Tetrahydropyran, LyondellBasell THF
Common Misclassification
Can be confused with acyclic ethers in 290919 if the cyclic nature is overlooked, or with other heterocyclic compounds in Chapter 29, especially those with oxygen in the ring.
Industry
This code belongs to the Chemicals industry.
Trade Overview
Major trade flows involve countries with advanced chemical and pharmaceutical industries, including Germany, the USA, Japan, and Switzerland, both as importers and exporters.
