Import Tips

• 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
