Product classification
HS code for Petroleum resin: 3911.10
Petroleum resins, coumarone, indene or coumarone-indene resins and polyterpenes, in primary forms.
Classification of petroleum resin under HS 3911.10
Petroleum resin is classified under HS code 3911.10 because it is a synthetic resin produced by the polymerization of unsaturated hydrocarbons derived from the cracking of petroleum fractions. These resins are typically low molecular weight polymers and are considered "primary forms" under the definitions provided in Chapter 39 of the Harmonized System. The classification is based on the chemical origin of the monomers and the fact that these resins do not fit into more specific polymer headings such as 3901 (polyethylene) or 3902 (polypropylene). They are characterized by their thermoplastic nature and are widely used as tackifiers in adhesives, printing inks, and rubber compounding.

Codes often confused with 3911.10
Common mistake. Petroleum resins are often confused with natural resins or rosin acids classified under HS code 3806.10. While they may serve similar industrial purposes, 3806 is reserved for products derived from vegetable sources (like pine trees), whereas 3911 is for synthetic petroleum-based products. They may also be misclassified under 3902.90 if the customs officer interprets them as "other" polymers of propylene, though 3911.10 is the more specific and correct heading for these hydrocarbon resins.
Top exporters and importers of HS 391110 (the code used for petroleum resin), 2025
In 2025, the largest exporter of HS 391110 (the code used for petroleum resin) in UN Comtrade data was China, with 35% of world exports; the largest importer in UN Comtrade data was the United States, with 7.7% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 391110, not only petroleum resin.

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).
