Colouring matter; lithopone and other pigments and preparations based on zinc sulphide

HS v2022 Code: 320642

About colouring matter; lithopone and other pigments and preparations based on zinc sulphide

HS code 320642 covers a diverse range of colouring materials and pigments based on zinc sulphide. These products play a crucial role in various industries, from paints and coatings to plastics and textiles. As a key component in the production of many consumer and industrial goods, the 320642 industry is an integral part of the broader global economy, contributing to the development and vibrancy of numerous sectors.

Production process

The production of colouring matter and pigments under HS code 320642 typically involves a multi-step process. The primary raw material, zinc sulphide, is first extracted and purified. It is then combined with other compounds, such as barium sulphate or titanium dioxide, to create the desired pigment formulations. These mixtures are then subjected to various chemical and mechanical processes, including milling, grinding, and dispersion, to achieve the required particle size, colour, and consistency for different applications.

Production inputs

The main inputs for the 320642 industry include zinc sulphide, barium sulphate, titanium dioxide, and other mineral and chemical compounds. Additionally, specialized production equipment, such as mills, grinders, and mixing tanks, are essential for the manufacturing process. The industry also relies on a skilled workforce to operate the equipment and ensure quality control throughout the production cycle.

Production outputs

The primary outputs of the 320642 industry are a wide range of colouring matter and pigments, including lithopone, zinc white, and other zinc-based pigments. These products are widely used in the manufacture of paints, coatings, plastics, rubber, and textiles, among other industries. The outputs of the 320642 industry are often consumed by industries covered under other HS codes, such as 320110 Pigments and preparations based on titanium dioxide, 320120 Pigments and preparations based on chromium compounds, and 320300 Colouring matter of vegetable or animal origin, as they serve as essential raw materials for their respective production processes.
