About HS Code 293352
This HS code covers heterocyclic compounds containing a pyrimidine ring (whether or not hydrogenated) or a piperazine ring in their structure, including malonylurea (barbituric acid) and its salts. These compounds are crucial building blocks for a vast array of pharmaceuticals, agrochemicals, and specialty chemicals. They are traded by pharmaceutical intermediates suppliers, fine chemical manufacturers, and research institutions globally. Key aspects of their trade include their role as versatile synthetic precursors for complex molecules and the strict regulatory control surrounding certain derivatives, especially those with pharmacological activity.
Products Under This Code
Barbituric acid, Pyrimidine, Piperazine, Malonylurea, Uracil, Thymine, Cytosine
Real World Examples
BASF (for intermediates), Lonza (for fine chemicals), Sigma-Aldrich (for research chemicals), Merck KGaA
Common Misclassification
Can be confused with other heterocyclic nitrogen compounds (e.g., 2933.59 for 'other' pyrimidine or piperazine compounds) or even specific pharmaceutical preparations (Chapter 30) if formulated.
Products Classified Under 2933.52
Industry
This code belongs to the Chemicals industry.
Trade Overview
China, India, Germany, and the USA are major players in the production and trade of these important chemical intermediates.
