Cerium compounds

HS v2022 Code: 284610

About cerium compounds

HS code 284610 covers cerium compounds, which are a group of chemical substances derived from the rare earth element cerium. Cerium is the most abundant of the rare earth metals and has a wide range of industrial applications, making it an important commodity in the global economy. These compounds are used in various industries, including catalysts, glass and ceramics, metallurgy, and electronics, contributing to technological advancements and economic growth.

Production process

Cerium compounds are typically produced through chemical processing of cerium-containing ores or recycled materials. The main production techniques involve extraction, purification, and chemical conversion processes to obtain the desired cerium compounds, such as cerium oxide, cerium chloride, or cerium nitrate. These processes often involve steps like leaching, precipitation, and thermal treatment to isolate and refine the cerium-based products.

Production inputs

The production of cerium compounds requires several key inputs, including cerium-bearing raw materials (such as monazite or bastnasite ores), various chemical reagents (e.g., acids, bases, or reducing agents), and specialized equipment for processing and purification. Additionally, energy sources, water, and skilled labor are essential inputs for the efficient and sustainable manufacture of these compounds.

Production outputs

Cerium compounds produced under HS code 284610 have a wide range of applications and are consumed by various other industries. These compounds are used as catalysts in automotive exhaust systems 870323 Motor cars and other motor vehicles principally designed for the transport of persons, as polishing agents in glass and ceramics production 701990 Other articles of glass, as additives in metallurgy 720290 Ferro-alloys, and in the manufacture of electronic components 854389 Other electrical machines and apparatus, having individual functions, not specified or included elsewhere in this chapter.
