HS Code 2930.70 – Organo-sulphur compounds; bis(2-hydroxyethyl)sulfide (thiodiglycol (INN))
HS code 2930.70 is the 6-digit subheading for organo-sulphur compounds, bis(2-hydroxyethyl)sulfide (thiodiglycol (INN)). It is used for thiodiglycol, bis(2-hydroxyethyl)sulfide, 2,2'-Thiodiethanol, di(2-hydroxyethyl)sulfide and thiodiglycol solvent.
What HS 2930.70 covers
Thiodiglycol is a chemical compound with diverse industrial applications, primarily known for its role as a solvent, a precursor in chemical synthesis, and in certain specialized applications. In international trade, this compound is crucial for industries ranging from textiles and dyes to pharmaceuticals and even military applications due to its historical use as a precursor for mustard gas, making its trade subject to strict regulations under chemical weapons conventions. Major importers are typically countries with robust chemical manufacturing sectors, particularly those involved in specialty chemicals, polymers, and pharmaceuticals. Exporters are often large chemical producers in industrialized nations. Key things to know include its dual-use nature, which necessitates careful compliance with export controls and non-proliferation treaties. Its stability and solvent properties also make it valuable in formulations where a high boiling point and good solvency are required. The global trade volume is influenced by demand from these specific industrial applications and the geopolitical landscape surrounding chemical weapon precursors.

Codes often confused with 2930.70
Common mistake. This code might be confused with other organo-sulphur compounds under 2930.90 if its specific chemical identity (thiodiglycol) is not clearly declared, or with other alcohols in Chapter 29 if its sulfur component is overlooked.
Top exporters and importers of HS code 293070, 2025
In 2025, the largest exporter of HS code 293070 in UN Comtrade data was Germany, with 73% of world exports; the largest importer in UN Comtrade data was the United States, with 53% 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).
