HS Code 2840.19 – Borates; disodium tetraborate (refined borax), other than anhydrous
HS code 2840.19 is the 6-digit subheading for borates, disodium tetraborate (refined borax), other than anhydrous. It is used for borax decahydrate, borax pentahydrate, refined borax crystals, borax powder and sodium borate.
What HS 2840.19 covers
This HS code encompasses disodium tetraborate, commonly known as refined borax, in its hydrated forms (e.g., borax decahydrate, borax pentahydrate), distinguishing it from the anhydrous version. These hydrated forms are widely utilized as a multi-purpose ingredient in cleaning products, detergents, cosmetics, and as a flux in metallurgy. They also find applications in agriculture as a boron micronutrient fertilizer and in the production of specialty glass and ceramics. International trade involves the movement of these compounds from countries rich in boron minerals to consumer goods manufacturers and agricultural sectors globally. Key factors in its trade include the specific degree of hydration, purity, and packaging, which can influence its handling and application. Its versatility ensures consistent demand across various industries.

Codes often confused with 2840.19
Common mistake. This code covers hydrated forms of disodium tetraborate and must be differentiated from the anhydrous form (2840.11). It also differs from boric acid (2810.00) or other borates (2840.20, 2840.30) which have distinct chemical structures and uses.

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).
