2919.10.00.00 - Tris(2,3-dibromopropyl phosphate)

This HTS classification, 2919.10.00.00, specifically covers Tris(2,3-dibromopropyl phosphate). This chemical compound is characterized by the presence of phosphate ester linkages and a specific tribromo-substituted propyl group. Its primary application has historically been as a flame retardant in textiles, particularly for children's sleepwear, although its use has been restricted or banned in many jurisdictions due to health concerns.

This category is distinct from its sibling, 2919.90, which encompasses "Other" phosphoric esters and their derivatives. While both fall under the broader heading of phosphoric esters, 2919.10.00.00 is a highly specific designation for a single chemical entity with a defined structure and known historical uses, whereas 2919.90 serves as a residual category for all other unlisted phosphoric esters, their salts, and their halogenated, sulfonated, nitrated, or nitrosated derivatives.

As 2919.10.00.00 is a leaf node in the HTS, there are no further subcategories. Classification under this heading relies on the precise chemical identification of Tris(2,3-dibromopropyl phosphate). Importers and exporters should ensure that the material being declared precisely matches the chemical structure and common nomenclature of this compound to avoid misclassification and potential duty discrepancies.
