Hydrogenated C9 Petroleum Resin from China
Hydrogenated C9 petroleum resin is a stabilized, low-odor version of aromatic hydrocarbon resin used in hot-melt adhesives and sealants. Classified in 3911.90.91 as 'other' petroleum resins in primary forms, as hydrogenation is a chemical modification not covered by specific subheadings per note (a)(3). It consists primarily of hydrogenated alkyl-aromatic monomers.

Import Tips
• Include hydrogenation process documentation to justify 'other' classification under chemically modified polymers
• Ensure primary form declaration (flakes/powder) and softening point specs (90-120°C typical) for CBP verification
