About HS Code 293321
This HS code specifically covers Hydantoin and its derivatives, which are heterocyclic compounds containing only nitrogen hetero-atoms and an unfused imidazole ring. Hydantoin is a versatile chemical intermediate with significant applications in the pharmaceutical industry, particularly for anticonvulsant drugs like phenytoin. It also finds use in cosmetics as a preservative (e.g., DMDM Hydantoin), in agrochemicals, and in the production of resins. Trade in these compounds is driven by chemical manufacturers, pharmaceutical companies, and cosmetic ingredient suppliers. Importers and exporters deal in bulk powders and specialized formulations, reflecting hydantoin's role as a foundational building block for various end products requiring its unique chemical properties.
Products Under This Code
Hydantoin, Phenytoin, Mephenytoin, Ethotoin, DMDM Hydantoin
Real World Examples
Dilantin (Phenytoin), specific cosmetic preservatives containing DMDM Hydantoin, generic hydantoin bulk chemicals from chemical suppliers
Common Misclassification
Can be confused with other nitrogen heterocyclics (e.g., 293329 for other imidazoles) or even other drug categories (e.g., 3004) if not in bulk form, but the specific hydantoin structure is key.
Products Classified Under 2933.21
Industry
This code belongs to the Chemicals industry.
Trade Overview
Countries with strong pharmaceutical and cosmetic industries, such as the USA, Germany, China, and India, are significant traders of these compounds.
