Phosphenon PMP-300 Flame Retardant Resin
Phosphenon PMP-300 is a commercial-grade poly(1,3-phenylene methylphosphonate) resin supplied in primary prill form, specifically designed for compounding into polycarbonate/ABS blends to enhance flame retardancy. This phosphorus-containing polymer is explicitly named in tariff item 3911.20.00, which covers poly(1,3-phenylene methylphosphonate) in primary forms, and meets the chapter's definition of plastics as a synthetic polymer capable of being formed under external influence.
3911.20.00PMMP Flame-Retardant Polymer Granules
PMMP Flame-Retardant Polymer Granules are poly(1,3-phenylene methylphosphonate) in primary granular form, used as a thermoplastic resin in engineering plastics to impart fire safety. This product falls under tariff item 3911.20.00, which specifically names poly(1,3-phenylene methylphosphonate) in primary forms, and is consistent with the chapter's classification of synthetic polymers with an average of at least 5 monomer units.
3911.20.00Poly(1,3-phenylene methylphosphonate) Resin Pellets
Poly(1,3-phenylene methylphosphonate) Resin Pellets are supplied in primary form as translucent pellets, specifically designed for processing into flame-retardant plastics. This phosphorus-containing polymer is explicitly enumerated in tariff item 3911.20.00, which covers poly(1,3-phenylene methylphosphonate) in primary forms, and meets the chapter's criteria for plastics as synthetic polymers capable of being molded or extruded.
3911.20.00TE-33 Polyphosphonate Primary Pellets
TE-33 Polyphosphonate Primary Pellets are a grade of poly(1,3-phenylene methylphosphonate) designed for extrusion into flame-retardant sheets and profiles. This primary-form polymer is specifically named in tariff item 3911.20.00, which covers poly(1,3-phenylene methylphosphonate) in primary forms, and is consistent with the chapter's classification of synthetic polymers with at least 5 monomer units.
