2933.35.00.00 - 3-Quinuclidinol

This HTS category, 2933.35.00.00, specifically covers the chemical compound 3-Quinuclidinol. As a heterocyclic compound, it features a nitrogen atom within a ring structure. More precisely, it falls under compounds containing an unfused pyridine ring, albeit in a hydrogenated form, and is classified within the broader group of organic chemicals in Section VI of the Harmonized Tariff Schedule.

Distinguishing 3-Quinuclidinol from its sibling categories is crucial for accurate classification. Unlike pyridine and its salts (2933.31.00.00) or piperidine and its salts (2933.32), 3-Quinuclidinol is a specific alcohol derivative of the quinuclidine bicyclic structure, which is a saturated diamine. It is also distinct from the extensive list of opioid analgesics and their derivatives found in codes like 2933.33.01.00 and 2933.34.00.00, as well as the specific piperidine derivative 4-Anilino-N-phenethylpiperidine (ANPP) under 2933.36.00.00.

As a leaf node, 3-Quinuclidinol does not have further subdivisions. Its classification as 2933.35.00.00 signifies a definitive placement for this particular chemical entity. When classifying, the presence of the quinuclidine ring system with the hydroxyl group at the 3-position is the defining characteristic that separates it from other nitrogen-containing heterocyclic compounds and directs its placement within this specific HTS code.
