HS code for 3-Quinuclidinol: 2933.35
Heterocyclic compounds, containing an unfused pyridine ring (whether or not hydrogenated) in the structure, 3-quinuclidinol.
Classification of 3-Quinuclidinol under HS 2933.35
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.

Codes often confused with 2933.35
Common mistake. 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.
Top exporters and importers of HS 293335 (the code used for 3-Quinuclidinol), 2025
In 2025, the largest exporter of HS 293335 (the code used for 3-Quinuclidinol) in UN Comtrade data was France, with 42% of world exports; the largest importer in UN Comtrade data was Italy, with 50% of world imports.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about 3-Quinuclidinol
What is the HS code for 3-Quinuclidinol?
The HS code for 3-Quinuclidinol is 293335 (Heterocyclic compounds; containing an unfused pyridine ring (whether or not hydrogenated) in the structure, 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.
How do I classify 3-Quinuclidinol for customs?
3-Quinuclidinol is classified under HS code 293335 — Heterocyclic compounds; containing an unfused pyridine ring (whether or not hydrogenated) in the structure, 3-quinuclidinol. This is a 6-digit subheading level code.
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.
Which countries are the top exporters of 3-Quinuclidinol (HS 293335)?
In 2025, the top exporters of HS 293335 (the code used for 3-Quinuclidinol) in UN Comtrade data were France ($337K, 42% of world exports), Germany ($326K) and Latvia ($109K). World exports came to about $800K, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of 3-Quinuclidinol (HS 293335)?
