2929.90.05.00/2,2'-Bis(4-cyanatophenyl)-1,1,1,3,3,3-hexafluoropropane/Germany

2,2'-Bis(4-cyanatophenyl)-1,1,1,3,3,3-hexafluoropropane from Germany

This is a fluorinated bis(cyanate ester) compound specifically listed in HTS 2929.90.0500, featuring two cyanato (-OCN) functional groups attached to phenyl rings linked by a hexafluoroisopropylidene bridge. It serves as a key monomer in high-performance polymer synthesis, particularly for fluorinated cyanate ester resins used in aerospace composites. The 'other nitrogen function' classification applies due to the cyanato group's nitrogen-oxygen structure.

Import Tips

• Provide detailed chemical analysis certificates confirming purity and structure matching the exact HTS listing to avoid reclassification

• Include Safety Data Sheets (SDS) highlighting fluorinated hazards and proper handling for transport compliance

• Verify no added stabilizers exceed chapter note (f) limits, as excess could shift classification
