HS Code 2920.22 – Esters; phosphite esters and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives, diethyl phosphite

HS code 2920.22 is the 6-digit subheading for esters, phosphite esters and their salts, their halogenated, sulphonated, nitrated or nitrosated derivatives, diethyl phosphite. It is used for diethyl phosphite, DEPI, diethyl hydrogen phosphite, phosphonic acid diethyl ester and intermediate chemical.

What HS 2920.22 covers

This HS code specifically covers diethyl phosphite, another crucial intermediate in organic synthesis, similar in application to dimethyl phosphite but with distinct chemical properties. It is widely used in the production of various agrochemicals, pharmaceuticals, and flame retardants. Its trade involves specialized chemical manufacturers exporting the compound, and diverse industrial sectors, particularly those in the agrochemical and pharmaceutical industries, importing it for further chemical reactions and product development. The global demand for diethyl phosphite is sustained by its versatility as a building block for complex organic molecules, making it a key component in the fine chemical market.

Codes often confused with 2920.22

Common mistake. Can be confused with dimethyl phosphite (292021) or trimethyl phosphite (292023) if the specific alkyl group (ethyl vs. methyl) is not accurately identified.

Top exporters and importers of HS code 292022, 2025

In 2025, the largest exporter of HS code 292022 in UN Comtrade data was India, with 38% of world exports; the largest importer in UN Comtrade data was the United States, with 61% 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).
