About HS Code 293332
This HS code specifically covers Piperidine and its salts, which are heterocyclic compounds containing an unfused, hydrogenated pyridine (piperidine) ring. Piperidine is a crucial intermediate in the synthesis of a wide range of pharmaceuticals, agrochemicals, and rubber chemicals. As a saturated heterocyclic amine, it serves as a versatile building block for various organic compounds, particularly in the creation of complex drug molecules and specialized polymers. Its trade is primarily driven by the pharmaceutical and chemical manufacturing sectors, with companies importing and exporting bulk quantities for use in complex synthesis pathways. It also finds niche applications as a solvent or catalyst in certain industrial processes.
Products Under This Code
Piperidine, Piperidine hydrochloride, N-Methylpiperidine, 4-Piperidone, 2-Piperidinecarboxylic acid
Real World Examples
Piperidine from Sigma-Aldrich, industrial-grade piperidine from chemical suppliers, specific research-grade piperidine derivatives
Common Misclassification
Often confused with pyridine (293331) due to structural similarity, but piperidine is the hydrogenated (saturated) form, which is a key distinction for classification.
Products Classified Under 2933.32
Industry
This code belongs to the Chemicals industry.
Trade Overview
Major chemical manufacturing nations such as China, India, Germany, and the USA are key players in the global trade of piperidine and its salts.
