HS Code 2930.30 – Organo-sulphur compounds; thiuram mono-, di- or tetrasulphides
HS code 2930.30 is the 6-digit subheading for organo-sulphur compounds, thiuram mono-, di- or tetrasulphides. It is used for tetramethylthiuram disulfide (TMTD), tetraethylthiuram disulfide (TETD), dipentamethylenethiuram tetrasulfide (DPTT), thiram and ziram.
What HS 2930.30 covers
This category covers specific organo-sulphur compounds, particularly thiuram mono-, di-, or tetrasulphides. These chemicals are indispensable in various industrial applications, most notably as accelerators in rubber vulcanization, as fungicides in agriculture, and as intermediates in other chemical syntheses. The primary importers and exporters are chemical suppliers, rubber manufacturers, and agricultural chemical companies. Key considerations in their trade include their specific chemical properties for desired applications, environmental regulations regarding their use, and the need for high purity to ensure efficacy in end products.

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).
