Heading 2933Heterocyclic 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.
