HS-4 · Heading
3911 — Petroleum resins, coumarone-indene resins, polyterpenes, polysulphides, polysulphones and similar products of chemical synthesis n.e.c. in chapter 39, in primary forms
Chapter 39: Plastics and articles thereof
Plain-language overview
Use HS-4 3911 when importing products like petroleum resins or polyterpenes in primary forms, such as a shipment of coumarone-indene resins for adhesive manufacturing. This code encompasses various synthetic materials that are crucial in industrial applications.
When deciding between 391110 and 391120, consider the specific type of resin. If you are importing coumarone or indene resins, use 391110. However, if your shipment includes poly(1,3-phenylene methylphosphonate), then 391120 is the correct choice. Each subheading targets distinct chemical compositions.
For products that do not fit neatly into the first two categories, 391190 covers polysulphides and polysulphones, as well as similar chemical products not classified elsewhere in chapter 39. This is important for ensuring accurate tariff classifications.
