HS Code 2830.90 – Sulphides and polysulphides; whether or not chemically defined, other than sulphides of sodium
HS code 2830.90 is the 6-digit subheading for sulphides and polysulphides, whether or not chemically defined, other than sulphides of sodium. It is used for calcium sulphide, barium sulphide, zinc sulphide, cadmium sulphide and carbon disulphide.
What HS 2830.90 covers
This HS code encompasses a broad range of sulphides and polysulphides, excluding those of sodium. These compounds, such as calcium sulphide, barium sulphide, and various organic polysulphides, are crucial in diverse industrial applications. They are used in pigments, luminescent materials, depilatories, and as vulcanizing agents in the rubber industry. Importers are typically countries with specialized manufacturing sectors, including those producing paints, rubber products, or specific chemical intermediates, such as Japan, South Korea, and various European nations. Exporters are often chemical manufacturing powerhouses like China, Germany, and the USA, which possess the technology and capacity for producing these varied compounds. Key trade considerations include managing the specific chemical properties and hazards of each sulphide, ensuring appropriate packaging for stability and safety, and adhering to international chemical regulations. The market is diverse, catering to specialized industrial demands across multiple sectors.

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).
