HS Code 3824.92 – Chemical products, mixtures and preparations; polyglycol esters of methylphosphonic acid
HS code 3824.92 is the 6-digit subheading for chemical products, mixtures and preparations, polyglycol esters of methylphosphonic acid. It is used for phosphate ester flame retardants, fire-resistant hydraulic fluids, polymer plasticizers, specialty lubricants and heat transfer fluids.
What HS 3824.92 covers
This HS code covers chemical products, mixtures, and preparations comprising polyglycol esters of methylphosphonic acid. These compounds are valued for their diverse industrial applications, often serving as flame retardants, plasticizers, or components in specialized hydraulic fluids and lubricants. Their phosphorus and glycol components contribute to enhanced fire resistance, improved lubrication, and better material flexibility. Key players in their trade include chemical producers, polymer manufacturers, and industries requiring high-performance fluids or fire-resistant materials. Important considerations for trade involve meeting specific performance specifications, ensuring compliance with environmental regulations (as they are often preferred over halogenated alternatives), and navigating regulatory approvals for their use in sensitive applications like aerospace or automotive industries.

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).
