It falls under HTS 2919.90.50 as a phosphoric ester (phosphate ester) that is not specifically enumerated elsewhere in heading 2919.

Import Tips

• Provide detailed chemical analysis (COA) confirming it's a non-halogenated phosphoric ester to avoid misclassification under 2919.90.20

• Ensure SDS includes CAS number (1330-78-5) and purity specs for CBP verification; common pitfall is incorrect Chapter 29 heading

• Declare as 'other' phosphoric esters explicitly; bulk shipments require proper UN packaging for flammability
