Nitrogen

HS v2017 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 a colorless, odorless gas that makes up approximately 78% of the Earth's atmosphere. It is an essential component in the production of fertilizers, chemicals, and various other products, making it a crucial resource for 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, where air is liquefied and then distilled to extract pure nitrogen gas.

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. Specialized equipment, such as compressors, heat exchangers, and distillation columns, are also essential for the efficient production of nitrogen.

Production outputs

The primary output of HS code 280430 is pure nitrogen gas, which is then used as a feedstock or input for various industries, including 280700 Ammonia, 310210 Urea, and 281410 Anhydrous ammonia. Nitrogen is also used in the production of industrial gases, electronics, and as a preservative in food and beverage packaging.
