2932.11.00.00 - Tetrahydrofuran

This HTS category, 2932.11.00.00, specifically covers Tetrahydrofuran (THF). Tetrahydrofuran is a colorless organic liquid with a low viscosity and a characteristic ether-like odor. It is a cyclic ether, meaning it contains an oxygen atom within a ring structure, and it is a fully hydrogenated derivative of furan. THF is widely used as a solvent in various industrial applications, including the production of polymers like polyvinyl chloride (PVC), in chemical synthesis, and as a solvent for adhesives, varnishes, and coatings.

Within the broader group of compounds containing an unfused furan ring, Tetrahydrofuran is distinguished from its siblings by its saturated (hydrogenated) ring structure. For instance, 2-Furaldehyde (furfuraldehyde) and Furfuryl alcohol are unsaturated furan derivatives and possess aldehyde or alcohol functional groups, respectively, which are absent in THF. Sucralose, another sibling, is a chlorinated carbohydrate sweetener, clearly differentiated by its chemical composition and intended use.

As Tetrahydrofuran is a terminal classification (a leaf node), there are no further subcategories. Classification within this code is determined by the precise chemical identity as Tetrahydrofuran, a key solvent and intermediate in organic chemistry. Importers and exporters should confirm that the substance being declared matches the chemical properties and common applications of Tetrahydrofuran to ensure accurate classification.
