HS Code for Tetrahydrofuran

Tetrahydrofuran (THF) is classified under HS code 2932.11. This classification is determined by its chemical structure as a heterocyclic compound containing an unfused furan ring that has been hydrogenated. According to the General Rules for the Interpretation of the Harmonized System (GIR), specifically Rule 1, classification is determined by the terms of the headings and any relative section or chapter notes. Chapter 29 covers organic chemicals, and heading 2932 specifically addresses heterocyclic compounds with oxygen hetero-atom(s) only. Within this heading, the subheadings are organized by the specific ring structure. Since THF is a saturated five-membered ring with one oxygen atom, it falls under the furan ring category. The specific subheading 2932.11 is reserved for tetrahydrofuran itself, recognizing its significance as a widely used industrial solvent and precursor to polymers like PTMEG. The classification remains consistent regardless of whether the THF is technical grade or highly purified, provided it remains a separate chemically defined organic compound. It is a colorless, water-miscible organic liquid with a low viscosity, often used in the production of adhesives, coatings, and as a reaction medium in chemical synthesis.

Common Misclassification

Tetrahydrofuran is frequently confused with other cyclic ethers or furan derivatives. It may be misclassified under HS code 2909.19, which covers acyclic ethers, or 2932.19, which is the residual category for other compounds containing an unfused furan ring. The distinction lies in the hydrogenation; 2932.11 is specific to the tetrahydro (fully hydrogenated) form. Additionally, if THF is mixed with other solvents for a specific industrial application, it might be classified under 3814.00 as a composite organic solvent.

FAQ

What is the HS code for Tetrahydrofuran?

The specific HS code for Tetrahydrofuran is 2932.11, which falls under the category of heterocyclic compounds with oxygen hetero-atoms.

Is Tetrahydrofuran classified differently if it contains stabilizers?

No, according to Note 1(f) to Chapter 29, the addition of a stabilizer (such as BHT) necessary for preservation or transport does not alter the classification of a separate chemically defined organic compound.
