Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing sulfur or other nonmetals/metals directly linked to carbon
Heading 2931.90 covers other organo-inorganic compounds beyond phosphorus derivatives; applies if molecule has additional heteroatoms like sulfur.
If classified as organo-sulfur compound with phosphorus as substituent
Organo-sulfur compounds take precedence in 2930 if sulfur-carbon bond defines character over phosphorus functionality.
If containing alcohol groups making it a phosphate ester of Chapter 29 subchapter III
Phosphate triesters fall in 2909.60; reclassification if OH groups present and oxygen-function defines principal characteristic.

Import Tips & Compliance
• Provide detailed chemical analysis and CAS number (if assigned) to confirm classification under 2931.47 as a non-halogenated organo-phosphorus derivative
• Ensure packaging complies with Chapter 29 note (e) for solvents used solely for safety/transport, avoiding retail-specific preparations
• Verify no halogen substitution to prevent misclassification into earlier halogenated organo-phosphorus headings
