HS Code 2931.45 – Non-halogenated organo-phosphorous derivatives; salt of methylphosphonic acid and (aminominomethyl) urea (1:1)
HS code 2931.45 is the 6-digit subheading for non-halogenated organo-phosphorous derivatives, salt of methylphosphonic acid and (aminominomethyl) urea (1:1). It is used for methylphosphonic acid-aminomethylurea salt, flame retardant additive, phosphorous-urea compound and fire-resistant chemical.
What HS 2931.45 covers
This HS code specifically identifies the salt of methylphosphonic acid and (aminominomethyl) urea (1:1), a specialized non-halogenated organo-phosphorous derivative. This compound is primarily utilized as a flame retardant or a component in fire-resistant materials, leveraging the synergistic properties of methylphosphonic acid and urea. It is traded by specialty chemical manufacturers and companies in the construction, textile, and electronics industries, where fire safety is paramount. Its application is driven by its ability to impart effective fire-retardant properties to various substrates, enhancing safety standards.

Top exporters and importers of HS code 293145, 2025
In 2025, the largest exporter of HS code 293145 in UN Comtrade data was Germany, with 77% of world exports; the largest importer in UN Comtrade data was France, with 16% of world imports. The United Arab Emirates did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 100% of its exports here ($688K, CEPII BACI), so it may also belong among the top exporters. Qatar did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 86% of its imports here ($688K, CEPII BACI), so it may also belong among the top importers.

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).
