Carbon dioxide

HS v2022 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 vital component in the production of a wide range of products, from carbonated beverages to fire extinguishers, making it a crucial part of the global economy. Its versatility and widespread use across multiple industries highlight the importance of this HS code within the broader import/export landscape.

Production process

Carbon dioxide is primarily produced through the combustion of fossil fuels, such as natural gas or coal, or through the fermentation of organic matter. The main production techniques involve capturing the carbon dioxide released during these processes and then purifying and liquefying the gas for storage and transportation. Advanced technologies, such as carbon capture and storage (CCS), are also being developed to capture and sequester carbon dioxide from industrial sources, further enhancing the sustainability of carbon dioxide production.

Production inputs

The main inputs required for the production of carbon dioxide include fossil fuels, such as natural gas or coal, as well as organic matter for fermentation processes. Additionally, specialized equipment, such as compressors, purification systems, and storage tanks, are necessary to capture, purify, and liquefy the carbon dioxide for distribution and use.

Production outputs

The primary outputs of HS code 281121 are liquefied and compressed carbon dioxide, which are then used as inputs for a variety of industries. Some of the main consumers of carbon dioxide include the 220210 Carbonated water industry, the 842430 Fire extinguishers industry, and the 281512 Carbonic acids industry, among others. Carbon dioxide is also used in the production of various chemicals, as a refrigerant, and in the food and beverage industry.
