HS v2022 Code: 320411

About dyes; disperse dyes and preparations based thereon

HS code 320411 covers the production and trade of disperse dyes and preparations based on these dyes. Disperse dyes are a class of synthetic dyes primarily used for coloring synthetic fibers, such as polyester, nylon, and acetate. They play a crucial role in the textile industry, allowing for the vibrant and long-lasting coloration of a wide range of fabrics. The global disperse dyes market is a significant component of the broader chemical industry, with applications extending beyond textiles to include plastics, coatings, and other industrial sectors.

Production process

The production of disperse dyes typically involves a multi-step chemical synthesis process. Key steps include the diazotization of aromatic amines, coupling reactions with active methylene compounds, and subsequent purification and formulation processes. Manufacturers utilize advanced chemical engineering techniques, such as batch or continuous reactors, to ensure consistent product quality and optimize production efficiency.

Production inputs

The primary inputs for the disperse dyes industry include aromatic amines, active methylene compounds, and various chemical reagents and solvents. Additionally, specialized production equipment, such as reactors, filtration systems, and drying units, are essential for the manufacturing process. The industry also relies on a skilled workforce with expertise in organic chemistry, process engineering, and quality control.

Production outputs

The primary output of HS code 320411 is disperse dyes, which are then used by 540200 Synthetic filament yarn and 540700 Woven fabrics of synthetic filament yarn manufacturers to color their products. These dyes are also consumed by 590190 Textile fabrics, impregnated, coated, covered or laminated with plastics, n.e.s. and 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials producers for coloring plastics and coatings.
