HTS US: 2932.XX.XXXX
Description
This heading encompasses heterocyclic chemical compounds that contain oxygen as the sole hetero-atom within their molecular structure. These compounds are characterized by ring structures where oxygen atoms are incorporated into the ring system, imparting unique chemical and physical properties.
The heading 2932 includes a variety of substances such as tetrahydrofuran, furfuraldehyde, furfuryl alcohols, sucralose, lactones, and other related oxygen-containing heterocyclic compounds. These chemicals are widely used in industrial applications, pharmaceuticals, pesticides, food additives, and chemical synthesis.

What is NOT Classified Here?
It is important to avoid misclassification by noting these exclusions:
- Heterocyclic compounds containing hetero-atoms other than oxygen are classified under different headings according to their hetero-atom composition.
- Non-cyclic oxygen-containing compounds are classified in other chapters or headings.
- Polymeric or macromolecular substances containing oxygen hetero-atoms are generally excluded.
