About HS Code 293491
This residual category covers a broad spectrum of heterocyclic compounds that contain both sulfur and nitrogen atoms in their ring structure, but do not specifically fall under the more defined categories of thiazole, benzothiazole, or phenothiazine ring systems (2934.10, 2934.20, 2934.30). These "other" compounds are diverse, finding applications across pharmaceuticals, agrochemicals, specialty polymers, and advanced materials. Importers are typically countries with strong chemical and pharmaceutical industries, such as China, India, Germany, and the United States, seeking novel intermediates or specialized chemicals for various manufacturing processes. Exporters are global fine chemical producers. Key aspects of their trade include the highly specialized nature of many of these compounds, often produced in smaller batches, and the need for precise chemical identification to ensure correct classification. The market is driven by continuous innovation in chemical synthesis and the demand for new materials with tailored properties.
Products Under This Code
Thiophene derivatives, Pyrimidine-2-thiol, 1,3,4-Thiadiazole, 1,2,4-Triazole-3-thiol, Benzothiophene, Dithianes, Thiazolidinediones
Real World Examples
Rosiglitazone (Avandia component), Pioglitazone (Actos component), Cimetidine (Tagamet precursor), Ranitidine (Zantac precursor)
Common Misclassification
This code is a "basket" category and is frequently confused with 2934.99, which is a broader "other" category for all heterocyclic compounds of heading 2934. The distinction lies in whether the compound contains sulfur and nitrogen in the ring, but not specifically the structures of 2934.10, 2934.20, or 2934.30.
Industry
This code belongs to the Chemicals industry.
Trade Overview
China, Germany, the United States, and India are major trading partners for these diverse "other" heterocyclic compounds.
