HS Code for Thiocarbamates

Thiocarbamates and dithiocarbamates are classified under HS code 2930.20. This classification is part of Chapter 29, which covers organic chemicals. Specifically, heading 2930 is designated for organo-sulphur compounds. These are organic compounds whose molecules contain one or more sulfur atoms directly linked to carbon atoms. Thiocarbamates are esters or salts of thiocarbamic acid, while dithiocarbamates are salts or esters of dithiocarbamic acid. The classification follows GRI 1 and GRI 6, focusing on the chemical structure of the compound. Because these substances contain both nitrogen and sulfur in a specific functional group, they are excluded from headings that cover simpler nitrogen-function compounds (such as 2924) and are instead placed in the more specific organo-sulphur category. These chemicals are widely used in agriculture as fungicides and in the rubber industry as vulcanization accelerators. The HS code 2930.20 is specific to the chemical identity of the substance rather than its end-use, provided it is a separate chemically defined compound as per the notes to Chapter 29.

Common Misclassification

Thiocarbamates are frequently misclassified under HS code 3808.92 (Fungicides) or 3808.91 (Insecticides). While many thiocarbamates are used as pesticides, they only fall under Chapter 38 if they are put up in forms or packings for retail sale or as finished preparations. If they are imported as pure bulk chemicals, 2930.20 is correct. They may also be confused with carbamates under 2924.29, which lack the sulfur atom required for heading 2930.
