HS-6 · Subheading
293354
Heterocyclic compounds; containing a pyrimidine ring (whether or not hydrogenated) or piperazine ring in the structure, other derivatives of malonylurea (barbituric acid) and salts thereof, n.e.c. in 2933.53
Heading 2933 — Heterocyclic compounds with nitrogen hetero-atom(s) only
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 293354 when importing or exporting heterocyclic compounds that contain a pyrimidine or piperazine ring. For instance, if you're shipping a pharmaceutical product that includes barbituric acid derivatives, this code applies.
This HS-6 line specifically covers compounds that are derivatives of malonylurea, such as those used in various medicinal applications. In contrast, HS-6 293353 includes similar compounds but focuses on those with different structural characteristics.
When dealing with heterocyclic compounds, it's essential to distinguish between those that are fully hydrogenated and those that are not. For example, a piperazine derivative might be classified under this code, while a simple piperazine without additional modifications would not.
If you are unsure whether your product fits this classification, consider the specific chemical structure and its intended use. For example, a compound used in a veterinary medicine formulation might also fall under this HS-6.
