HS code for Thiocarbamates: 2930.20

Organo-sulphur compounds, thiocarbamates and dithiocarbamates.

Classification of thiocarbamates under HS 2930.20

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.

Codes often confused with 2930.20

Common mistake. 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.

Top exporters and importers of HS 293020 (the code used for thiocarbamates), 2025

In 2025, the largest exporter of HS 293020 (the code used for thiocarbamates) in UN Comtrade data was China, with 43% of world exports; the largest importer in UN Comtrade data was Australia, with 12% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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 thiocarbamates

What is the HS code for Thiocarbamates?

The HS code for Thiocarbamates is 293020 (Organo-sulphur compounds; thiocarbamates and dithiocarbamates). The HS code for thiocarbamates and dithiocarbamates is 2930.20, classified as organo-sulphur compounds.

How do I classify Thiocarbamates for customs?

Thiocarbamates is classified under HS code 293020 — Organo-sulphur compounds; thiocarbamates and dithiocarbamates. This is a 6-digit subheading level code.

Are these used in rubber manufacturing?

Yes, many dithiocarbamates are used as ultra-accelerators in the vulcanization process of natural and synthetic rubbers.

Which countries are the top exporters of thiocarbamates (HS 293020)?

In 2025, the top exporters of HS 293020 (the code used for thiocarbamates) in UN Comtrade data were China ($252M, 43% of world exports), India ($159M) and Japan ($48M). World exports came to about $590M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).
