Piperidine
Piperidine is a saturated six-membered heterocyclic amine with the formula C5H10NH, containing a nitrogen hetero-atom in the ring structure. This chemically defined organic compound falls under HTS 2933.32.10.00 as it is specifically listed as piperidine, a hydrogenated pyridine derivative.
Piperidine Hydrochloride
Piperidine hydrochloride is the salt form of piperidine (C5H10NH·HCl), commonly used in organic synthesis. It qualifies under HTS 2933.32.10.00 per Chapter Note 5(C)(1) which classifies salts of organic compounds with the parent compound.
Stabilized Piperidine with Antioxidant
Industrial piperidine stabilized with BHT antioxidant for safe transport and storage. Chapter Note 1(f) specifically allows classification as piperidine when stabilizers are added solely for preservation.
