HS v2017 Code: 320411

About dyes; disperse dyes and preparations based thereon

HS code 320411 covers the trade and production of disperse dyes and preparations based on these dyes. Disperse dyes are a class of water-insoluble dyes primarily used for dyeing synthetic fibers such as polyester, nylon, and acetate. They play a crucial role in the textile industry, allowing for the vibrant coloration of fabrics that are in high demand globally. The disperse dyes industry is a significant contributor to the broader chemical and textile manufacturing sectors, supporting economic activity and employment across the supply chain.

Production process

The production of disperse dyes typically involves a multi-step chemical synthesis process. Key steps include the nitration of aromatic compounds, reduction to form amino groups, and subsequent coupling reactions to create the desired dye structures. Specialized equipment such as reactors, distillation columns, and drying systems are utilized to ensure consistent quality and yield throughout the manufacturing process.

Production inputs

The primary inputs for the disperse dyes industry include aromatic compounds, reducing agents, coupling agents, and various solvents and catalysts. Manufacturers also rely on specialized machinery and equipment, as well as skilled labor, to carry out the complex chemical synthesis and processing required. Access to a reliable supply of these raw materials and production resources is essential for the industry to meet the demands of textile producers and other downstream consumers.

Production outputs

The main output of HS code 320411 is disperse dyes, which are then used by textile manufacturers, apparel producers, and other industries that require the coloration of synthetic fabrics. These dyes may be consumed under other HS codes, such as 540200 Synthetic filament yarn and 550300 Synthetic staple fibres, as they are integral to the dyeing and finishing of these textile products.
