HS Code 2809.20 – Phosphoric acid and polyphosphoric acids

HS code 2809.20 is the 6-digit subheading for phosphoric acid and polyphosphoric acids. It is used for phosphoric acid 85%, food-grade phosphoric acid, industrial-grade phosphoric acid, polyphosphoric acid and technical-grade phosphoric acid.

What HS 2809.20 covers

Phosphoric acid and polyphosphoric acids are vital inorganic chemicals with a broad spectrum of applications, making them significant players in international trade, particularly in the agricultural and food sectors. The vast majority of phosphoric acid produced globally is used to manufacture phosphate fertilizers, essential for crop growth and food security. Beyond agriculture, it is widely used in the food and beverage industry as an acidulant, flavor enhancer, and preservative (e.g., in soft drinks). Other important uses include metal treatment (rust removal, passivation), detergents, pharmaceuticals, and water treatment. Polyphosphoric acids, more concentrated forms, are used in specialized chemical syntheses and as dehydrating agents. Major importers are typically agricultural nations and countries with large food processing industries. Exporters are often countries with significant phosphate rock reserves or advanced chemical processing capabilities. Key aspects of its trade include its role as a bulk commodity, with prices influenced by phosphate rock costs and agricultural demand. While less corrosive than some other mineral acids, proper handling and storage are still crucial. Its indispensable role in food production and industrial processes ensures its continuous high demand in global markets.

Codes often confused with 2809.20

Common mistake. This code covers phosphoric acid and polyphosphoric acids. It can be confused with diphosphorus pentoxide (280910), which is a precursor to phosphoric acid, or with phosphate salts (Chapter 28 or 31 for fertilizers), which are derived from phosphoric acid.

Top exporters and importers of HS code 280920, 2025

In 2025, the largest exporter of HS code 280920 in UN Comtrade data was Morocco, with 46% of world exports; the largest importer in UN Comtrade data was India, with 40% 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. 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).
