HS Code for 3-Quinuclidinol

3-Quinuclidinol is classified under HS code 2933.35 due to its chemical structure as a heterocyclic compound containing an unfused pyridine ring, which is hydrogenated within the quinuclidine system. Chapter 29 of the Harmonized System covers organic chemicals, and heading 2933 is specifically dedicated to heterocyclic compounds with nitrogen hetero-atom(s) only. The subheading 2933.35 precisely identifies "3-quinuclidinol," ensuring its accurate and unambiguous classification. This specific designation facilitates consistent customs declaration and international trade by clearly defining the product's chemical identity within the global tariff system, distinguishing it from other nitrogen-containing heterocyclic compounds.

Common Misclassification

Common misclassifications for 3-Quinuclidinol often involve other heterocyclic compounds containing nitrogen. It might be confused with other pyridine derivatives that are not quinuclidinol, which would typically fall under HS code 2933.39 for "other" compounds containing an unfused pyridine ring. Additionally, other heterocyclic compounds containing nitrogen but with different ring structures or without an unfused pyridine ring might be mistakenly considered, potentially leading to classification under 2933.99, which covers "other" nitrogen heterocyclic compounds. Confusion with compounds containing other heteroatoms, such as oxygen (HS code 2932), is also a potential misclassification.

FAQ

What is the HS code for 3-Quinuclidinol?

The HS code for 3-Quinuclidinol is 2933.35. This code specifically identifies this chemical compound within the broader category of heterocyclic compounds containing an unfused pyridine ring (whether or not hydrogenated) in the structure, ensuring precise classification.

What is an unfused pyridine ring in the context of HS classification?

In the context of HS classification, an unfused pyridine ring refers to a pyridine ring that is not part of a polycyclic system where it shares more than two atoms with another ring. Quinuclidine contains a hydrogenated pyridine ring system, which, despite its bicyclic nature, is considered to contain an unfused pyridine ring for the purpose of this classification due to its specific structural characteristics.
