Product classification
HS code for Tetrahydrofuran: 2932.11
Heterocyclic compounds, with oxygen hetero-atom(s) only, containing an unfused furan ring (whether or not hydrogenated) in the structure, tetrahydrofuran.
Classification of tetrahydrofuran under HS 2932.11
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.

Codes often confused with 2932.11
Common mistake. 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.
Top exporters and importers of HS 293211 (the code used for tetrahydrofuran), 2025
In 2025, the largest exporter of HS 293211 (the code used for tetrahydrofuran) in UN Comtrade data was China, with 32% of world exports; the largest importer in UN Comtrade data was India, with 20% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about tetrahydrofuran
What is the HS code for Tetrahydrofuran?
The HS code for Tetrahydrofuran is 293211 (Heterocyclic compounds; with oxygen hetero-atom(s) only, containing an unfused furan ring (whether or not hydrogenated) in the structure, tetrahydrofuran). The specific HS code for Tetrahydrofuran is 2932.11, which falls under the category of heterocyclic compounds with oxygen hetero-atoms.
How do I classify Tetrahydrofuran for customs?
Tetrahydrofuran is classified under HS code 293211 — Heterocyclic compounds; with oxygen hetero-atom(s) only, containing an unfused furan ring (whether or not hydrogenated) in the structure, tetrahydrofuran. This is a 6-digit subheading level code.
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.
Which countries are the top exporters of tetrahydrofuran (HS 293211)?
In 2025, the top exporters of HS 293211 (the code used for tetrahydrofuran) in UN Comtrade data were China ($72M, 32% of world exports), Germany ($48M) and Belgium ($22M). World exports came to about $221M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of tetrahydrofuran (HS 293211)?
In 2025, the top importers of HS 293211 (the code used for tetrahydrofuran) in UN Comtrade data were India ($48M, 20% of world imports), South Korea ($25M) and Belgium ($23M). World imports came to about $235M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
