HS-6 · Subheading
293331
Heterocyclic compounds; containing an unfused pyridine ring (whether or not hydrogenated) in the structure, pyridine and its salts
Heading 2933 — Heterocyclic compounds with nitrogen hetero-atom(s) only
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 293331 when importing or exporting pyridine and its salts, which are commonly used in pharmaceuticals and agrochemicals. For example, a shipment of pyridine-based solvents would fall under this code.
This code specifically applies to heterocyclic compounds that contain an unfused pyridine ring. In contrast, HS-6 293332 covers pyridine derivatives that are fused with other rings, which can change their classification significantly.
Pyridine is a colorless liquid with a distinct odor, often found in products like herbicides and insecticides. If you deal with pyridine salts, such as pyridinium chloride, this HS-6 is also applicable.
When classifying your products, consider whether they contain only the pyridine structure or additional components that might lead to a different HS classification. This can affect import duties and compliance requirements.
