HS code for Tris(2,3-dibromopropyl) phosphate: 2919.10
Esters, phosphoric, and their salts, including lactophosphates, their halogenated, sulphonated, nitrated or nitrosated derivatives, tris(2,3-dibromopropyl) phosphate.
Classification of tris(2,3-dibromopropyl) phosphate under HS 2919.10
Tris(2,3-dibromopropyl) phosphate is classified under HS code 2919.10. This chemical is a phosphoric ester and is specifically identified within the Harmonized System due to its historical use as a flame retardant and its subsequent regulation under international environmental agreements. Chapter 29 covers organic chemicals, and heading 2919 covers phosphoric esters and their salts, including lactophosphates and their derivatives. Subheading 2919.10 is reserved specifically for Tris(2,3-dibromopropyl) phosphate. This classification requires the product to be a separate chemically defined compound. It is a halogenated derivative, containing bromine, which is why it is distinguished from other phosphoric esters. Due to its toxicity and persistence in the environment, accurate classification is essential for regulatory compliance and monitoring by customs authorities.

Codes often confused with 2919.10
Common mistake. The most frequent misclassification is HS code 2919.90, which is the residual category for other phosphoric esters. Because Tris(2,3-dibromopropyl) phosphate is explicitly named in 2919.10, the residual code should not be used. Additionally, it is often confused with HS code 3824.83, which is intended for mixtures containing this substance rather than the pure chemical itself.
Top exporters and importers of HS 291910 (the code used for tris(2,3-dibromopropyl) phosphate), 2025
In 2025, the largest exporter of HS 291910 (the code used for tris(2,3-dibromopropyl) phosphate) in UN Comtrade data was the Netherlands, with 63% of world exports; the largest importer in UN Comtrade data was Canada, with 39% 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).
