Polyphosphoric Acid 115% from Germany
Polyphosphoric acid with approximately 115% H3PO4 equivalent, a viscous, colorless to yellow liquid used primarily as a phosphorylating agent in organic synthesis. It falls under HTS 2809.20.00.40 as a chemically defined polyphosphoric acid, distinguished from monophosphoric acid by its polymeric structure and higher phosphorus oxide content.

Import Tips
• Verify purity and P2O5 content via certificate of analysis to confirm classification under polyphosphoric acids, not simple phosphoric acid
• Ensure UN-approved packaging (e.g
• IBCs with corrosion-resistant liners) and proper Hazmat documentation (UN1805, Class 8)
• Avoid misclassification as fertilizer-grade phosphoric acid; provide lab specs showing polymeric structure
