Hydrocarbon Petroleum Resin C5
A thermoplastic resin derived from C5 petroleum byproducts, containing aromatic monomer units from its polymerization process. Classified under HTS 3911.90.25.00 as a petroleum resin in primary form, meeting the criteria for aromatic-derived thermoplastic products not elsewhere specified.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily C9 aromatic monomers without modification
Pure C9 petroleum resins fall under 3911.10 as specified petroleum resins, not the 'other' aromatic thermoplastic category.
If chemically modified beyond aromatic derivation
Heavily modified versions may classify as other polyesters in 3907 if not predominantly aromatic monomers per note (a)(3).
If imported in sheets or plates exceeding 38.1 cm width
Processed into non-primary forms like sheets shifts to 3921 plates/sheets per US note limitations on primary forms.

Import Tips & Compliance
• Verify monomer composition via lab analysis to confirm aromatic content exceeds predominant threshold per subheading note (a)(4)
• Ensure certificate of analysis specifies primary pellet or granular form, avoiding classification as compounded plastics in 3920
• Declare exact petroleum derivation to prevent misclassification under generic polymers
