Pentaerythritol Ester of Rosin
Pentaerythritol ester of rosin is a tall oil derivative used in inks, technically a polyterpene ester. 3911.90.91 as modified polyterpene, though borderline with 3806.
Liquid Polysulfide Polymer
Liquid polysulfide polymer (LP-3 type) for sealants, mercaptan-terminated. 3911.90.91 as polysulfides primary liquid form.
C5 Aliphatic Petroleum Resin
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.
Hydrogenated C9 Petroleum Resin
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.
Coumarone-Indene Resin
Coumarone-indene resin is a synthetic thermoplastic derived from coal tar fractions, used as a binder in rubber and adhesives. It qualifies for HTS 3911.90.91 as specified in note 3 to Chapter 39, in primary forms like pastilles, with coumarone/benzofuran and indene monomers predominant.
Polyterpene Resin from Pinene
Beta-pinene polyterpene resin is polymerized from turpentine-derived monomers, serving as a tackifier in pressure-sensitive adhesives. Falls under 3911.90.91 as polyterpenes in primary forms (granules), explicitly named in chapter note 3 with >95% terpene monomer content.
