Gases; coal, water, producer and similar gases (excluding petroleum and other gaseous hydrocarbons)

HS code 270500 covers a diverse range of industrial gases, including coal gas, water gas, producer gas, and other similar gaseous products. These gases play a crucial role in various manufacturing and energy-related processes, serving as essential inputs for a wide array of industries. The production and trade of these gases are integral to the global economy, supporting the operations of numerous sectors, from steel production to chemical processing.

The primary production techniques for the gases covered under HS code 270500 involve the gasification or partial combustion of solid fuels, such as coal, biomass, or waste materials. This process typically takes place in specialized gasification plants or furnaces, where the solid feedstock is heated in a controlled environment, resulting in the release of the desired gaseous products. The specific methods used may vary depending on the type of gas being produced and the desired purity or composition of the final output.

The main inputs required for the production of the gases under HS code 270500 include solid fuels, such as coal, coke, or biomass, as well as air or oxygen for the gasification process. Depending on the type of gas being produced, additional inputs may include water, catalysts, or other processing chemicals. The production facilities also require specialized equipment, such as gasifiers, compressors, and purification systems, to ensure the efficient and safe conversion of the solid feedstock into the desired gaseous products.

The primary outputs of the industries covered under HS code 270500 are the various types of industrial gases, including coal gas, water gas, producer gas, and other similar gaseous products. These gases are then consumed by a wide range of industries, such as 720110 Iron and non-alloy steel in ingots or other primary forms, 281410 Anhydrous ammonia, and 281511 (Sodium hydroxide (caustic soda), solid), where they serve as essential inputs for various manufacturing and energy-related processes.
