HS-6 · Subheading
293349
Heterocyclic compounds; containing a quinoline or isoquinoline ring-system (whether or not hydrogenated) in the structure, not further fused, other than levorphanol (INN) and its salts
Heading 2933 — Heterocyclic compounds with nitrogen hetero-atom(s) only
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 293349 when importing or exporting heterocyclic compounds that contain a quinoline or isoquinoline ring system, such as certain pharmaceuticals or chemical intermediates. For example, a shipment of a quinoline derivative used in dye manufacturing would fall under this code.
This code specifically covers compounds that are not further fused and excludes substances like levorphanol and its salts. If you're dealing with a compound that has additional fused rings, you may need to look at other HS codes within this heading.
When comparing HS-6 293349 to HS-6 293348, the latter covers similar compounds but includes those that are hydrogenated. Ensure you check the specific structure of your compound to choose the correct classification.
Proper classification is essential for compliance and duty assessment. If you're unsure whether your product fits this HS-6, consulting with a customs broker can provide clarity.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What types of products fall under HS-6 293349?
- HS-6 293349 covers heterocyclic compounds that contain a quinoline or isoquinoline ring system, specifically those that are not further fused.
- Are there any exclusions for HS-6 293349?
- Yes, this code excludes levorphanol and its salts, so ensure your product does not fall into that category.
- How can I determine if my compound is fused?
- A fused compound has additional rings sharing atoms with the main ring. If your compound has only a single quinoline or isoquinoline structure, it is not fused.
- Can I use HS-6 293349 for pharmaceutical applications?
- Yes, if the pharmaceutical product contains a quinoline or isoquinoline structure and meets the criteria outlined in the code.
- What should I do if I'm unsure about the classification?
- Consult with a customs broker or trade specialist who can help you accurately classify your product based on its chemical structure.
- What are the consequences of misclassifying my product?
- Misclassification can lead to incorrect duty assessments, potential fines, and delays in customs clearance.
- How do I find the right HS code for my chemical compound?
- Review the detailed descriptions in the HS nomenclature and consult with experts if needed to ensure accurate classification.
