Carbon dioxide

HS v2017 Code: 281121

About carbon dioxide

HS code 281121 covers the classification of carbon dioxide, a colorless, odorless gas that is essential for various industrial and commercial applications. Carbon dioxide is a fundamental compound in the global carbon cycle and plays a crucial role in the production of numerous products across diverse industries, making it a vital component of the broader economy.

Production process

Carbon dioxide is primarily produced through the combustion of fossil fuels, such as natural gas, coal, and oil. The gas is also a byproduct of various industrial processes, including the production of cement, steel, and chemicals. Additionally, carbon dioxide can be captured from the atmosphere or extracted from natural gas and other industrial sources, and then purified and liquefied for storage and transportation.

Production inputs

The main inputs required for the production of carbon dioxide include fossil fuels, industrial processes that generate the gas as a byproduct, and specialized equipment for the capture, purification, and liquefaction of the gas. Machinery and infrastructure for the storage, transportation, and distribution of carbon dioxide are also essential inputs for this industry.

Production outputs

The primary outputs of the carbon dioxide industry are the liquefied and compressed forms of the gas, which are then used as inputs for a wide range of industries, including 292111 Food and Beverage, 202111 Chemical Manufacturing, and 325120 Industrial Gas Manufacturing. Carbon dioxide is a critical component in the production of carbonated beverages, the manufacture of various chemicals, and the provision of industrial gases for various applications.
