Oxygen

HS v2022 Code: 280440

About oxygen

HS code 280440 covers the classification of oxygen, a vital element that plays a crucial role in various industries and everyday life. Oxygen is a colorless, odorless, and highly reactive gas that is essential for the survival of most living organisms on Earth. It is a key component in the production of numerous goods and services, making it a fundamental part of the global economy.

Production process

Oxygen is primarily produced through the fractional distillation of liquefied air. This process involves cooling air to extremely low temperatures, causing the different gases in the air to separate based on their boiling points. The oxygen is then collected and purified, ready for use in various applications.

Production inputs

The main inputs required for the production of oxygen include air, electricity, and specialized equipment such as air separation units, compressors, and cryogenic storage tanks. The production process also requires a significant amount of energy to cool the air and maintain the necessary low temperatures.

Production outputs

The primary output of HS code 280440 is pure oxygen gas, which is then used as an input for a wide range of industries, including 281100 Hydrogen, rare gases and other non-metals, 281410 Ammonia, anhydrous or in aqueous solution, and 300210 Antisera, other blood fractions and immunological products. Oxygen is also a crucial component in medical applications, industrial processes, and environmental technologies.
