HS Code 2814.20 – Ammonia; in aqueous solution
HS code 2814.20 is the 6-digit subheading for ammonia, in aqueous solution. It is used for ammonia water, ammonium hydroxide, aqueous ammonia, household ammonia and cleaning ammonia.
What HS 2814.20 covers
Ammonia in aqueous solution, commonly known as ammonia water or ammonium hydroxide, is a solution of ammonia gas dissolved in water. Unlike its anhydrous counterpart, this form is less concentrated and generally safer to handle, though still corrosive. It is widely traded for various industrial and household applications. Key uses include as a cleaning agent, a laboratory reagent, a component in some fertilizers (though less concentrated than anhydrous ammonia), and in the textile industry for dyeing and finishing. It also finds application in water treatment and as a pH regulator. Importers and exporters range from chemical distributors and cleaning product manufacturers to agricultural suppliers and industrial processors. While less hazardous than anhydrous ammonia, its trade still requires adherence to safety protocols for corrosive liquids. The "CBAM" tag indicates its inclusion in carbon border adjustment mechanisms, reflecting the carbon footprint associated with its production.

Codes often confused with 2814.20
Common mistake. This code covers ammonia dissolved in water, clearly differentiating it from anhydrous ammonia (2814.10), which is pure, concentrated ammonia gas.
Top exporters and importers of HS code 281420, 2025
In 2025, the largest exporter of HS code 281420 in UN Comtrade data was Egypt, with 23% of world exports; the largest importer in UN Comtrade data was France, with 15% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
