HS v2022 Code: 290219

About cyclic hydrocarbons; cyclanes, cyclenes and cycloterpenes, excluding cyclohexane

HS code 290219 covers a range of cyclic hydrocarbon compounds, excluding cyclohexane. These compounds are widely used in the chemical industry as solvents, intermediates, and building blocks for various products. They play a crucial role in the production of pharmaceuticals, plastics, and other essential materials, making this industry a vital component of the broader chemical and manufacturing sectors.

Production process

The production of cyclic hydrocarbons under HS code 290219 typically involves a combination of chemical synthesis and purification processes. The starting materials, which may include natural gas, petroleum fractions, or other hydrocarbon sources, undergo a series of reactions, such as cyclization, isomerization, and dehydrogenation, to form the desired cyclic compounds. Distillation, extraction, and other separation techniques are then used to isolate and purify the target products.

Production inputs

The main inputs required for the production of cyclic hydrocarbons under HS code 290219 include various hydrocarbon feedstocks, such as 271011 Petroleum oils and oils obtained from bituminous minerals, other than crude, 271112 Propane, liquefied, and 271113 Butanes, liquefied. Additionally, the industry relies on specialized equipment, such as reactors, distillation columns, and purification systems, as well as a skilled workforce with expertise in chemical engineering and process optimization.

Production outputs

The cyclic hydrocarbons produced under HS code 290219 are used as intermediates and solvents in a wide range of industries. They are commonly used in the production of 290531 (Ethylene glycol (ethanediol)), 290711 (Phenol (hydroxybenzene) and its salts), and 290243 p-Xylene, among other important chemical products. The outputs from this industry are often consumed by manufacturers in the pharmaceutical, plastics, and specialty chemicals sectors.
