3911.90.15.00/Stabaxol P 200 Polymer Resin/Mexico

Stabaxol P 200 Polymer Resin from Mexico

Stabaxol P 200 is a specialized thermoplastic polymer resin classified under HTS 3911.90.15.00, consisting of poly(nitrilomethanetetraarylnitrilo-[2,4,6-tris-(1-methyethyl)-1,3-phenylene]]-2,6-bis(1-methylethyl)-phenyl]-ω-[[[2,6-bis(1-methylethyl)-phenyl]amino]methylene]amino carbodiimide homopolymer blended with polyethylene. It serves as a carbodiimide stabilizer for polyurethane and polyurea systems, preventing hydrolysis in moisture-exposed applications. The aromatic monomer units exceeding 95% by weight determine its specific subheading placement per Chapter 39 notes.

Import Tips

• Verify polymer composition certificate showing aromatic monomer units >95% by weight to confirm HTS 3911.90.15.00 classification per subheading note (a)(1)

• Include Safety Data Sheets (SDS) documenting primary form (pellets/granules) and non-chemically modified status

• Avoid misclassification as generic polysulfones (3911.90.25) by specifying exact monomer structure in entry docs
