Iron oxides and hydroxides

HS code 282110 covers a range of iron oxides and hydroxides, which are essential inorganic compounds with a wide variety of industrial applications. These materials play a crucial role in various sectors, including pigments, catalysts, water treatment, and the production of iron and steel. As a key component in the broader iron and steel industry, the iron oxides and hydroxides described by this code are integral to the global economy.

The production of iron oxides and hydroxides typically involves the oxidation of iron or the precipitation of iron compounds from aqueous solutions. Common methods include the thermal decomposition of iron salts, the hydrolysis of iron salts, and the direct oxidation of iron metal. The specific techniques used can vary depending on the desired product characteristics, such as particle size, purity, and crystal structure.

The main inputs required for the production of iron oxides and hydroxides include iron-bearing raw materials, such as iron ore, scrap iron, or iron salts. Additionally, various chemical reagents, such as acids, bases, and oxidizing agents, may be used to facilitate the production process. Specialized equipment, such as reactors, filtration systems, and drying units, are also essential for the efficient manufacture of these materials.

The iron oxides and hydroxides produced under HS code 282110 have a wide range of applications. They are commonly used as pigments in paints, coatings, and inks 320611 Pigments and preparations based on titanium dioxide, as catalysts in chemical processes 381512 Supported catalysts, and in water treatment applications 382490 Chemical products and preparations of the chemical or allied industries.
