HS-6 · Subheading
293311
Heterocyclic compounds; with nitrogen hetero-atom(s) only, containing an unfused pyrazole ring (whether or not hydrogenated) in the structure, phenazone (antipyrin) and its derivatives
Heading 2933 — Heterocyclic compounds with nitrogen hetero-atom(s) only
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 293311 when importing or exporting heterocyclic compounds that contain an unfused pyrazole ring, such as phenazone (antipyrin) and its derivatives. For example, if you're shipping a pharmaceutical product that contains phenazone for pain relief, this code applies.
This code is specific to compounds with nitrogen hetero-atoms and an unfused pyrazole structure, distinguishing it from similar compounds like those classified under HS-6 293312, which includes fused pyrazole rings. Understanding this difference is crucial for proper classification.
If your product is a derivative of phenazone, such as a specific analgesic formulation, you will also use HS-6 293311. However, if it contains other hetero-cyclic structures or additional functional groups, you may need to consider other HS codes.
When dealing with chemical shipments, ensure your product descriptions are precise. For instance, mentioning the specific use or formulation can help clarify the correct classification under this HS line.

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-6 293311?
- HS-6 293311 covers heterocyclic compounds with nitrogen, specifically those containing an unfused pyrazole ring, including phenazone and its derivatives.
- Can I use HS-6 293311 for all pyrazole compounds?
- No, HS-6 293311 is specific to unfused pyrazole rings. If your compound has a fused structure, you may need to use a different HS code.
- What documentation do I need for importing products under HS-6 293311?
- You typically need a commercial invoice, packing list, and any relevant safety data sheets or certificates of analysis for the chemicals.
- How do I determine if my product qualifies for HS-6 293311?
- Check if your product contains an unfused pyrazole ring and nitrogen hetero-atoms. Consulting with a customs broker can also help clarify classification.
- Are there any restrictions on importing phenazone?
- Phenazone may be subject to specific regulations or restrictions depending on your country’s laws regarding pharmaceuticals. Always check local regulations.
- What is the difference between HS-6 293311 and HS-6 293312?
- HS-6 293311 includes unfused pyrazole rings, while HS-6 293312 covers fused pyrazole structures. Ensure you classify correctly based on your product's structure.
- Can I export pyrazole derivatives classified under HS-6 293311?
- Yes, as long as you comply with both your country’s export regulations and the import regulations of the destination country.
