Petroleum resins, coumarone, indene or coumarone-indene resins and polyterpenes; in primary forms

HS code 391110 covers a range of synthetic resins that are widely used in various industries, including adhesives, coatings, and plastics. These resins are derived from petroleum and are known for their excellent adhesive properties, thermal stability, and resistance to chemicals. They play a crucial role in the production of a wide array of consumer and industrial products, making them an essential component of the global economy.

The production of the resins covered under HS code 391110 typically involves the polymerization of various hydrocarbon feedstocks, such as petroleum fractions, coal tar, or natural terpenes. The specific production techniques may vary, but they often include processes like thermal cracking, catalytic polymerization, or distillation to obtain the desired resin properties.

The main inputs required for the production of the resins under HS code 391110 include various petroleum-based feedstocks, such as 271012 Petroleum oils and oils obtained from bituminous minerals, other than crude; preparations not elsewhere specified or included, containing by weight 70% or more of petroleum oils or of oils obtained from bituminous minerals, these oils being the basic constituents of the preparations; waste oils, 271019 Petroleum oils and oils obtained from bituminous minerals, other than crude; preparations not elsewhere specified or included, containing by weight 70% or more of petroleum oils or of oils obtained from bituminous minerals, these oils being the basic constituents of the preparations; other, and 271320 Petroleum bitumen. Additionally, catalysts, solvents, and other chemical additives may be used in the production process.

The resins covered under HS code 391110 are primarily used as raw materials in the production of a wide range of products, including 391190 Petroleum resins, coumarone, indene or coumarone-indene resins and polyterpenes, in primary forms, not elsewhere specified or included, 391400 Ion-exchangers based on polymers of headings 3901 to 3913, in primary forms, and 391690 Monofilament of which any cross-sectional dimension exceeds 1 mm, rods, sticks and profile shapes, whether or not surface-worked but not otherwise worked, of plastics, not elsewhere specified or included. These resins are also used in the production of adhesives, coatings, and various types of plastics.
