Tris(2,3-dibromopropyl) Phosphate (TRIS)
TRIS is a halogenated phosphoric ester used primarily as a flame retardant additive in polyurethane foams and plastics. It falls under HTS 2919.10.00.00 as it is specifically named tris(2,3-dibromopropyl phosphate), a brominated derivative of phosphoric acid esters. This chemical compound provides fire resistance without significantly altering material properties.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed as other halogenated phosphoric esters
Products not specifically named as tris(2,3-dibromopropyl phosphate) fall under the residual 'other' provision in the same heading.
If when imported as flame retardant mixture with solvents or stabilizers
Mixtures containing >70% flame retardants with additives are classified as chemical preparations rather than pure compounds.
If considered primarily as brominated alcohol derivative
Alternative classification possible if brominated alcohol function predominates over phosphoric ester structure per chapter notes.

Import Tips & Compliance
• Verify chemical purity and provide Certificate of Analysis (CoA) confirming identity as tris(2,3-dibromopropyl phosphate) to match exact HTS specification
• Include Safety Data Sheets (SDS) detailing brominated flame retardant properties and TSCA compliance for US EPA registration
• Avoid misclassification as generic phosphate esters; precise chemical name matching is required for this specific subheading
