Gases, rare; other than argon

HS v2017 Code: 280429

About gases, rare; other than argon

HS code 280429 covers the classification of rare gases, excluding argon. These gases, such as neon, helium, and krypton, play a vital role in various industries, from lighting and electronics to medical applications and scientific research. As essential components in numerous products and processes, the rare gases industry is a crucial part of the broader chemical and industrial sectors, contributing to technological advancements and economic growth worldwide.

Production process

The production of rare gases typically involves the separation and purification of these elements from air or other natural sources. The most common method is cryogenic distillation, where air is cooled and compressed, allowing the different gases to be separated based on their boiling points. Other techniques, such as adsorption and membrane separation, may also be employed depending on the specific gas and its intended use.

Production inputs

The main inputs required for the production of rare gases include air or other natural gas sources, as well as specialized equipment such as compressors, heat exchangers, and distillation columns. Additionally, the industry relies on skilled personnel, including chemical engineers and technicians, to operate and maintain the production facilities.

Production outputs

The primary outputs of the rare gases industry are the individual gases, such as 280429 Gases, rare; other than argon, 280421 Argon, 280429 Neon, 280429 Helium, and 280429 Krypton. These gases are then consumed by a wide range of industries, including 851110 Spark-ignition reciprocating or rotary internal combustion piston engines, 901831 Syringes, with or without needles, and 901890 Instruments and appliances used in medical, surgical or veterinary sciences, n.e.s., among others.
