HS Code for THF

Tetrahydrofuran (THF) is classified under HS code 2932.11 based on its chemical structure as a heterocyclic compound containing an unfused furan ring. According to the General Interpretative Rules (GIR) 1 and 6, the classification is determined by the specific description provided in the subheadings of heading 2932. Heading 2932 is designated for heterocyclic compounds with oxygen hetero-atom(s) only. Subheading 2932.11 specifically names tetrahydrofuran. The compound is a cyclic ether with the formula (CH2)4O. Because it contains a five-membered ring with four carbon atoms and one oxygen atom, and this ring is not fused to any other ring system, it meets the criteria for an "unfused furan ring" as specified in the tariff nomenclature. This classification is straightforward for the pure chemical or for THF containing stabilizers, provided the stabilizers do not render the product suitable for specific use rather than general use. THF is widely used as an industrial solvent and as a precursor to polymers like PTMEG, and its classification remains consistent across most global jurisdictions due to its specific mention in the Harmonized System.

Products Included

• Pure Tetrahydrofuran (THF)
• THF with added stabilizers (e.g., BHT)
• Reagent grade THF for laboratory use
• Industrial grade THF for polymer production
• THF used as a solvent in chromatography

Common Misclassification

THF is sometimes misclassified under HS code 2932.19, which is the "other" category for compounds containing an unfused furan ring. However, since THF is explicitly named in 2932.11, the specific code must take precedence. Another common misclassification is HS code 3814.00, which covers organic composite solvents and thinners. If THF is part of a mixture of solvents, it belongs in 3814, but the pure substance must remain in 2932.11. Occasionally, it is confused with other cyclic ethers like 1,4-dioxane, which is classified under 2932.99.

FAQ

What is the HS code for THF?

The HS code for Tetrahydrofuran is 2932.11. This is a specific code for the pure chemical compound.

Is THF classified differently if it contains stabilizers?

No, as long as the stabilizers are added only for preservation or transport and do not change the product's character for a specific use, it remains under 2932.11.
