HS Code 3911.10 – Petroleum resins, coumarone, indene or coumarone-indene resins and polyterpenes; in primary forms
HS code 3911.10 is the 6-digit subheading for petroleum resins, coumarone, indene or coumarone-indene resins and polyterpenes, in primary forms. It is used for C5 petroleum resins, C9 petroleum resins, coumarone-indene resins, polyterpene resins and hydrogenated petroleum resins.
What HS 3911.10 covers
This HS code covers a specific group of hydrocarbon resins in primary forms, including petroleum resins, coumarone, indene or coumarone-indene resins, and polyterpenes. These resins are derived from petroleum fractions or natural terpenes and are primarily traded as tackifiers, binders, and processing aids. They are crucial components in adhesives, sealants, coatings, printing inks, and rubber compounding, enhancing properties like adhesion, water resistance, and processability. Importers are typically manufacturers in the packaging, automotive, construction, and tire industries. Exporters are often petrochemical companies. The international trade in these resins is driven by their cost-effectiveness and ability to improve the performance of various end products, making them essential additives in a wide range of industrial formulations.

Codes often confused with 3911.10
Common mistake. Can be confused with other synthetic resins like phenolic resins (390940) or epoxy resins (390730) if not specifically hydrocarbon-based, or with other petroleum products (Chapter 27) if not processed into resins.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
