Import Tips

• 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
