HS-6 · Subheading
293332
Heterocyclic compounds; containing an unfused pyridine ring (whether or not hydrogenated) in the structure, piperidine and its salts
Heading 2933 — Heterocyclic compounds with nitrogen hetero-atom(s) only
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 293332 when importing or exporting heterocyclic compounds that contain an unfused pyridine ring, such as piperidine. For example, if you're shipping piperidine hydrochloride for pharmaceutical applications, this is the correct code.
This code specifically covers piperidine and its salts, distinguishing it from similar compounds like pyridine itself, which falls under a different classification. If you deal with piperazine instead, you would use a different HS-6 code.
Heterocyclic compounds like those classified under HS-6 293332 are commonly used in the production of pharmaceuticals, agrochemicals, and other specialized chemicals. Understanding this classification helps ensure compliance and accurate tariff application.
When considering related compounds, note that HS-6 293331 covers other nitrogen-containing heterocycles without the unfused pyridine structure, which may lead to different applications and regulatory requirements.
