HS Code 2920.29 – Esters; phosphite esters and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives, n.e.c. in heading no. 2920

HS code 2920.29 is the 6-digit subheading for esters, phosphite esters and their salts, their halogenated, sulphonated, nitrated or nitrosated derivatives, n.e.c. in heading no. 2920. It is used for triisopropyl phosphite, triphenyl phosphite, tributyl phosphite, tris(2-ethylhexyl) phosphite and diallyl phosphite.

What HS 2920.29 covers

This residual HS code encompasses phosphite esters and their salts, along with their halogenated, sulphonated, nitrated, or nitrosated derivatives, that are not specifically enumerated in other subheadings of 2920. These 'not elsewhere specified' compounds are diverse, serving as intermediates in complex organic syntheses, specialty additives, or niche agrochemicals. Trade involves specialized chemical producers exporting these unique compounds, often in smaller volumes, and various R&D-intensive industries or manufacturers requiring specific chemical properties importing them. This category highlights the vast array of specialized organic chemicals traded globally, catering to highly specific industrial needs and advanced chemical research.

Codes often confused with 2920.29

Common mistake. This 'n.e.c.' code is a catch-all, but care must be taken to ensure the phosphite ester is not specifically listed under 292021-292024 or other more specific codes.

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).
