HS Code 2931.47 – Non-halogenated organo-phosphorous derivatives; (5-ethyl-2-methyl-2-oxido-1,3,2-dioxaphosphinan-5-yl) methyl methyl methylphosphonate
What HS 2931.47 covers
HS code 293147 identifies (5-ethyl-2-methyl-2-oxido-1,3,2-dioxaphosphinan-5-yl) methyl methyl methylphosphonate, another highly specific non-halogenated organo-phosphorous derivative. This compound is a specialty chemical, often used as an intermediate in the synthesis of advanced materials, flame retardants, or specific polymer additives. Its complex structure suggests niche applications where precise chemical properties are required, such as in high-performance plastics, coatings, or lubricants. Importers are typically R&D-intensive chemical companies, specialty polymer manufacturers, and pharmaceutical intermediates producers. Exporters are often specialized chemical synthesis firms. Understanding its exact molecular function and purity is critical for trade, as it's not a commodity but a high-value, low-volume specialty chemical.

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).
