HS Code for Petroleum resin

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.

Products Included

• C5 aliphatic petroleum resins
• C9 aromatic petroleum resins
• Hydrogenated petroleum resins
• Coumarone-indene resins
• Mixed C5/C9 hydrocarbon resins

Common Misclassification

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.

FAQ

What is the HS code for Petroleum resin?

The HS code for petroleum resins, including coumarone, indene, or coumarone-indene resins in primary forms, is 3911.10.

Are petroleum resins considered plastics?

In the context of the HS nomenclature, they are classified in Chapter 39 (Plastics and articles thereof) because they are synthetic polymers in primary forms.
