About phosphides, chemically defined or not, not ferrophosphorus; other inorganic compounds n.e.c. (including distilled, conductivity water and water of like purity); liquid air, rare gases removed or not; compressed air; amalgams, not precious metal amalgams

HS code 285390 covers a diverse range of inorganic chemical compounds and related products. These materials play a crucial role in various industrial processes, from water purification to specialty gas production. As an important part of the broader chemicals and materials industry, this code represents a significant segment of international trade and economic activity.

Production process

The production of the items under HS code 285390 involves a range of chemical synthesis and processing techniques. Phosphides, for example, are typically manufactured through the reaction of phosphorus with various metallic elements. Other inorganic compounds may be produced via distillation, electrolysis, or other separation and purification methods. The production of liquid air and rare gases often relies on cryogenic distillation and liquefaction processes.

Production inputs

The main inputs required for the industries covered by HS code 285390 include raw materials such as phosphorus, metals, and other elemental substances. Specialized equipment like distillation columns, reaction vessels, and gas separation units are also essential. Skilled labor, energy sources, and various auxiliary materials like catalysts and solvents are additional key inputs.

Production outputs

The outputs of the industries under HS code 285390 are diverse, ranging from phosphides and other inorganic compounds to specialty gases and high-purity water. These products find applications in 282000 Inorganic chemical industries, 281000 Manufacture of basic chemicals, and 271000 Manufacture of coke and refined petroleum products, among others. The specific end-use industries will depend on the nature and properties of the individual compounds and materials.
