Heterocyclic compounds; with nitrogen hetero-atom(s) only, containing an unfused imidazole ring (whether or not hydrogenated) in the structure, hydantoin and its derivatives

Heading 2933Heterocyclic compounds with nitrogen hetero-atom(s) only

Chapter 29: Organic chemicals

Plain-language overview

Use HS-6 293321 when importing or exporting heterocyclic compounds that contain an unfused imidazole ring, such as hydantoin and its derivatives. For example, if you are shipping a pharmaceutical ingredient that features this specific chemical structure, this code applies.

This code specifically covers compounds with nitrogen hetero-atoms only, distinguishing them from other heterocyclic compounds that may include different elements. For instance, HS-6 293322 includes compounds with additional hetero-atoms beyond nitrogen, which would not qualify for this classification.

When dealing with hydantoin derivatives, such as 5-methylhydantoin, it's crucial to use this HS code to ensure proper classification. This code is tailored for those specific compounds, while other related compounds might fall under different HS lines.

If you're unsure whether your product fits this classification, consider the structure of the compound. If it contains an imidazole ring and is primarily nitrogen-based, you are likely looking at HS-6 293321.
