Colouring matter; pigments and preparations based on chromium compounds

HS v2017 Code: 320620

About colouring matter; pigments and preparations based on chromium compounds

HS code 320620 covers a range of chromium-based pigments and colouring agents used in various industries. These chromium compounds are essential for producing vibrant, long-lasting colours in paints, inks, plastics, and other materials. The global chromium pigments market is a crucial component of the broader 32 Manufacture of other chemical products industry, contributing to the manufacturing of diverse consumer and industrial products.

Production process

The production of chromium-based pigments and colouring matter typically involves several key steps. First, chromium ore is extracted and processed to obtain chromium compounds, such as chromium oxide or chromium hydroxide. These compounds are then combined with other materials, like binders and dispersants, to create the desired pigment formulations. The mixture is then milled, blended, and sometimes subjected to additional chemical treatments to enhance its properties, such as colour intensity, durability, and compatibility with different application media.

Production inputs

The main inputs required for the production of HS code 320620 products include chromium ore, various chemical reagents, and specialized production equipment. Chromium ore, the primary raw material, is typically mined and processed to extract the necessary chromium compounds. Other key inputs may include binders, dispersants, and various additives that help to optimize the pigment's performance characteristics. Additionally, the industry relies on milling, blending, and other specialized processing equipment to manufacture the final chromium-based colouring matter and pigments.

Production outputs

The chromium-based pigments and colouring matter produced under HS code 320620 find widespread application in a variety of industries. These outputs are commonly used as colourants in 32 Manufacture of paints, varnishes and similar coatings, printing ink and mastics, 22 Manufacture of rubber and plastic products, and 23 Manufacture of other non-metallic mineral products, among others. The versatility of chromium pigments allows them to be incorporated into a wide range of products, from paints and inks to plastics and ceramics, contributing to the vibrant and durable colours that are essential in many consumer and industrial applications.
