HS Code 2511.10 – Barium sulphate (barytes); natural
HS code 2511.10 is the 6-digit subheading for barium sulphate (barytes), natural. It is used for barytes ore, barite lumps, natural barium sulfate, drilling-grade barite and filler-grade barite.
What HS 2511.10 covers
This HS code covers natural barium sulphate, commonly known as barytes or barite, in its raw, unprocessed form. Barytes is a heavy mineral primarily valued for its high specific gravity and chemical inertness. Its most significant application is as a weighting agent in drilling fluids for oil and gas exploration, where it helps control well pressure and prevent blowouts. Other uses include as a filler in paints, plastics, and rubber, and as a source of barium for chemical manufacturing. Major importers are countries with active oil and gas industries or significant manufacturing sectors, such as the USA, China, and various European nations. Exporters are typically countries with abundant barytes deposits, including China, India, and Morocco. Key considerations in trade include purity, specific gravity (often expressed as API grade), and particle size, which dictate its suitability for different industrial applications.

Top exporters and importers of HS code 251110, 2025
In 2025, the largest exporter of HS code 251110 in UN Comtrade data was India, with 17% of world exports; the largest importer in UN Comtrade data was the United States, with 28% 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).
