Nitrogen

HS v2022 Code: 280430

About nitrogen

HS code 280430 covers the classification of nitrogen, a vital element that plays a crucial role in various industries. Nitrogen is the most abundant element in the Earth's atmosphere, making up approximately 78% of the air we breathe. This colorless, odorless gas is an essential raw material for the production of a wide range of products, from fertilizers to industrial chemicals, making it a crucial component of the global economy.

Production process

Nitrogen is primarily produced through the process of air separation, where atmospheric air is cooled and compressed, allowing the different gases to be separated based on their boiling points. The most common method is the cryogenic distillation of air, which involves cooling the air to extremely low temperatures and then separating the various components, including nitrogen, oxygen, and argon.

Production inputs

The main inputs required for the production of nitrogen include atmospheric air, as well as energy sources such as electricity or natural gas to power the air separation process. Additionally, specialized equipment, such as compressors, heat exchangers, and distillation columns, are necessary to facilitate the separation and purification of nitrogen from the air.

Production outputs

The primary output of HS code 280430 is pure nitrogen gas, which is then used as a raw material in various industries. Some of the key industries that consume nitrogen include 281410 Ammonia, 310210 Urea, and 281511 (Sodium hydroxide (caustic soda)). Nitrogen is also used in the production of 290110 Saturated acyclic hydrocarbons, 290121 Ethylene, and 290122 (Propene (propylene)), as well as in the food and beverage industry for preservation and packaging purposes.
