Colouring matter; pigments and preparations based on chromium compounds

HS v2022 Code: 320620

About colouring matter; pigments and preparations based on chromium compounds

HS code 320620 covers a diverse range of chromium-based pigments and colouring agents used across various industries. These chromium compounds play a vital role in the production of paints, inks, plastics, and other materials, contributing to the vibrant colors and durable finishes that are essential in modern manufacturing and design. As a key component of the broader chemical industry, the 320620 product group represents an important segment of international trade and economic activity.

Production process

The production of chromium-based pigments and colouring agents typically involves the extraction and processing of chromium-containing ores, such as chromite. The raw materials undergo a series of chemical reactions and purification steps to isolate the desired chromium compounds, which are then formulated into stable pigments or other preparations. Advanced techniques like precipitation, calcination, and micronization are often employed to achieve the desired particle size, color, and performance characteristics.

Production inputs

The main inputs for the 320620 industry include chromium-bearing ores and minerals, as well as various chemical reagents and processing aids. Specialized equipment such as reactors, filtration systems, and drying units are also essential for the production of these chromium-based products. Additionally, the industry relies on a skilled workforce with expertise in chemical processing, quality control, and product development.

Production outputs

The outputs of the 320620 industry encompass a wide range of chromium-based pigments, colouring agents, and related preparations. These products find applications in the manufacturing of 320111 Pigments and preparations based on titanium dioxide, 320120 Pigments and preparations based on chromium compounds, 320190 Other colouring matter; preparations as specified in Note 3 to this Chapter, and various other industries, including paints, inks, plastics, and textiles.
