Coal gas, water gas, producer gas and similar gases, other than petroleum gases and other gaseous hydrocarbons

HS v2022 Code: 2705

About coal gas, water gas, producer gas and similar gases, other than petroleum gases and other gaseous hydrocarbons

HS code 2705 covers a range of gaseous fuels produced from coal, including coal gas, water gas, and producer gas. These gases play a crucial role in various industrial processes and power generation, serving as important energy sources in the broader economy. The production and utilization of these gases contribute to the efficient use of coal, a widely available and economically significant fossil fuel.

Production process

The main production techniques for the gases covered under HS code 2705 involve the thermal processing of coal. This typically involves the partial combustion or gasification of coal, where the coal is heated in the absence of sufficient oxygen to produce a fuel gas. The specific methods used can include coal gasification, coke oven gas production, and the operation of producer gas plants, among others. These processes aim to extract the energy content of coal in a more versatile and environmentally friendly gaseous form.

Production inputs

The primary input for the production of the gases under HS code 2705 is coal, which serves as the raw material. In addition to coal, these processes may require other inputs such as air, steam, and various catalysts or reagents to facilitate the gasification or combustion reactions. The production facilities also rely on specialized equipment, including gasifiers, retorts, and gas cleaning and purification systems, to convert the coal into the desired gaseous products.

Production outputs

The main outputs of the industries covered by HS code 2705 are the various types of fuel gases, including coal gas, water gas, and producer gas. These gases can be used as energy sources in a wide range of industrial applications, such as 2710 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 for heating, power generation, and as feedstocks for the production of other chemicals and fuels.
