HS-6 · Subheading
293491
Heterocyclic compounds; other heterocyclic compounds, n.e.c. in 2934.1, 2934.2 and 2934.3
Heading 2934 — Nucleic acids and their salts, whether or not chemically defined; other heterocyclic compounds
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 293491 when importing or exporting certain heterocyclic compounds that are not chemically defined. For example, if you’re shipping a pharmaceutical intermediate that contains a nitrogen-containing ring structure, this code may apply.
This code specifically covers heterocyclic compounds that do not fall under the more defined categories in HS-6 293490, which includes compounds with specific chemical structures. If your product is a defined nucleic acid or a more specific heterocyclic compound, you would need to look at those classifications instead.
Compounds classified under HS-6 293491 can include various unclassified heterocyclic substances used in pharmaceuticals, agrochemicals, or specialty chemicals. For instance, a compound used in a research lab for drug development may fit here.
When considering this classification, it’s important to differentiate it from HS-6 293492, which covers other specific heterocyclic compounds with defined structures. If your product has a specific chemical formula, you may need to use that code instead.
