About HS Code 293311
This HS code specifically covers Phenazone (Antipyrin) and its derivatives, which are heterocyclic compounds containing only nitrogen hetero-atoms and an unfused pyrazole ring. Historically, phenazone was widely used as an analgesic and antipyretic, though its use has become more limited due to the availability of safer alternatives. Today, these compounds find niche applications in certain pharmaceutical formulations, as intermediates in the synthesis of other drugs, and in chemical research. Trade is primarily driven by pharmaceutical manufacturers, bulk drug producers, and fine chemical suppliers. Importers and exporters are typically companies involved in the production of active pharmaceutical ingredients (APIs) or specialized chemical synthesis, often dealing in bulk powder form for further processing.
Products Under This Code
Phenazone (Antipyrin), Propyphenazone, Metamizole (Dipyrone), Aminophenazone, Nifenazone
Real World Examples
Novalgin (Metamizole), Saridon (contains Propyphenazone), specific generic phenazone products, research-grade antipyrin
Common Misclassification
Can be confused with other non-steroidal anti-inflammatory drugs (NSAIDs) under 293399 or other analgesic compounds in Chapter 29, but the pyrazole ring and specific derivatives are key here.
Products Classified Under 2933.11
Industry
This code belongs to the Chemicals industry.
Trade Overview
Countries with a history of using these older analgesics, particularly in parts of Europe, Asia, and Latin America, are significant importers and exporters.
