HS Code 2840.11 – Borates; disodium tetraborate (refined borax), anhydrous
HS code 2840.11 is the 6-digit subheading for borates, disodium tetraborate (refined borax), anhydrous. It is used for anhydrous borax powder, calcined borax, disodium tetraborate anhydrous, borax frit and borax glass.
What HS 2840.11 covers
This HS code specifically covers anhydrous disodium tetraborate, commonly known as anhydrous borax or calcined borax. It's a highly concentrated form of borax, obtained by removing water from hydrated borax, making it more efficient for transport and storage. Anhydrous borax is a crucial raw material in the production of glass (especially borosilicate glass), ceramics, enamels, and metallurgical fluxes. It's also used in detergents and as a flame retardant. International trade involves countries with significant boron mineral deposits and processing facilities supplying industrial users worldwide. Key considerations include purity, particle size, and its role in high-temperature applications. Its demand is closely linked to the construction, automotive, and electronics industries.

Codes often confused with 2840.11
Common mistake. This code is specifically for the anhydrous form of disodium tetraborate. It is crucial to distinguish it from hydrated forms of disodium tetraborate (2840.19) and other borates (2840.20 or 2840.30), as their physical properties and applications differ.
Top exporters and importers of HS code 284011, 2025
In 2025, the largest exporter of HS code 284011 in UN Comtrade data was the United States, with 43% of world exports; the largest importer in UN Comtrade data was China, with 27% 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).
