C5 Aliphatic Petroleum Resin from China
C5 aliphatic petroleum resin is a thermoplastic resin derived from the C5 fraction of petroleum cracking, used primarily as a tackifier in adhesives and hot-melt coatings. It falls under HTS 3911.90.91 as a petroleum resin in primary forms (pellets or granules), not elsewhere specified, meeting the chapter note criteria for polymers specified in note 3. This classification applies because it is a hydrocarbon resin with predominant C5 monomer units exceeding 95% by weight.

Import Tips
• Verify monomer composition via lab analysis to confirm >95% C5 content per subheading note (a)(1) to avoid reclassification
• Provide supplier certificates specifying primary form (e.g
• granules <5mm) and non-phenolic nature to support NES status
