HS-6 · Subheading
293319
Heterocyclic compounds; with nitrogen hetero-atom(s) only, containing an unfused pyrazole ring (whether or not hydrogenated) in the structure, other than henazone (antipyrin) and its derivatives
Heading 2933 — Heterocyclic compounds with nitrogen hetero-atom(s) only
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 293319 when importing or exporting heterocyclic compounds that contain nitrogen and feature an unfused pyrazole ring. For example, a shipment of a pyrazole-based pharmaceutical intermediate would fall under this code.
This code specifically excludes henazone (antipyrin) and its derivatives, which are classified separately. If you're dealing with a compound that has a similar structure but is a derivative of henazone, you’ll need to look at a different classification.
Heterocyclic compounds under this heading are primarily used in pharmaceuticals, agrochemicals, and specialty chemicals. If you have a compound that includes an unfused pyrazole ring but is not a derivative of henazone, it likely belongs here.
When comparing to HS-6 293320, which covers pyrazole derivatives like henazone, it's crucial to ensure your product does not fit that category to avoid misclassification.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What types of products are classified under HS code 293319?
- HS code 293319 covers heterocyclic compounds with nitrogen that contain an unfused pyrazole ring, excluding henazone and its derivatives. This includes various pharmaceutical intermediates and specialty chemicals.
- How can I tell if my compound is a derivative of henazone?
- If your compound has structural similarities to henazone or is derived from it, it likely falls under HS code 293320 instead. Review the chemical structure and consult with a customs broker if unsure.
- Are there any specific documentation requirements for importing under this code?
- Yes, you may need to provide detailed chemical composition, safety data sheets, and possibly a certificate of origin to ensure proper classification and compliance with regulations.
- Can I use HS code 293319 for pyrazole derivatives?
- No, if your product is a derivative of henazone, it should be classified under HS code 293320. Only non-derivative pyrazole compounds fit under HS 293319.
- What industries commonly use compounds classified under HS 293319?
- Compounds under HS 293319 are primarily used in pharmaceuticals, agrochemicals, and specialty chemicals for various applications.
- How do I ensure my classification is correct for customs?
- Consult with a customs broker or trade compliance expert to review your product details and ensure it aligns with the correct HS code.
