PMMP Flame-Retardant Polymer Granules from Germany
PMMP (Poly(1,3-phenylene methylphosphonate)) granules are primary-form thermoplastic resin used in engineering plastics for fire safety. Classified under HTS 3911.20.00.00 as the specifically enumerated phosphonate polymer meeting 95% monomer content requirement. These granules require melt processing into final flame-retardant components.

Import Tips
• Provide FTIR/ NMR analysis confirming PMMP structure and purity; avoid common pitfall of declaring as generic 'phosphorus plasticizer' which shifts to 3904; check for anti-dumping on Asian-sourced phosphonate polymers
