Thiodicarb Technical
Thiodicarb technical is an insecticide with an aromatic heterocyclic structure containing both oxygen and sulfur hetero-atoms. Despite the sulfur, it is classified under tariff item 2932.99.00 because the oxygen hetero-atom ring is the defining feature, and it is not more specifically covered elsewhere.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the sulfur hetero-atom is considered the primary functional group
Organo-sulphur compounds are classified in heading 29.30 when the sulphur atoms are directly linked to carbon and are not merely incidental to the oxygen heterocycle.

Import Tips & Compliance
• Confirm the product is not formulated as a retail preparation, which would shift classification to Chapter 38
• Provide a certificate of analysis to prove it is a separate chemically defined compound for tariff purposes
