Ammonia; in aqueous solution

HS code 281420 covers the classification of ammonia in aqueous solution, a widely used chemical compound with diverse industrial applications. Ammonia is a colorless, pungent gas that is highly soluble in water, forming an alkaline solution. This chemical is a fundamental building block for a range of products, making it a crucial component in the global chemical industry and international trade.

Ammonia in aqueous solution is primarily produced through the Haber process, a high-temperature, high-pressure reaction between hydrogen and nitrogen gases. The hydrogen is typically derived from natural gas or other hydrocarbon sources, while the nitrogen is extracted from the air. The resulting ammonia is then dissolved in water to create the aqueous solution covered under HS code 281420.

The main inputs required for the production of ammonia in aqueous solution include natural gas or other hydrocarbon feedstocks, air, and water. Specialized equipment such as compressors, reactors, and distillation columns are also necessary to facilitate the Haber process and the subsequent dissolution of the ammonia gas.

Ammonia in aqueous solution, classified under HS code 281420, is a versatile chemical with a wide range of applications. It is commonly used in the production of fertilizers, as a cleaning agent, and in the manufacture of other chemicals such as 281410 Anhydrous ammonia and 310221 Ammonium sulphate.
