Dyes; reactive dyes and preparations based thereon

HS v2017 Code: 320416

About dyes; reactive dyes and preparations based thereon

HS code 320416 covers reactive dyes and preparations based on these dyes. Reactive dyes are a crucial component in the textile industry, enabling the coloration of fabrics through a chemical reaction that binds the dye to the fabric fibers. This industry plays a vital role in the global textile supply chain, providing the necessary colorants to meet the diverse aesthetic and functional requirements of textile products across various applications, from apparel to home furnishings.

Production process

The production of reactive dyes involves a multi-step process. First, the base dye compound is synthesized through chemical reactions. This is then modified to incorporate reactive functional groups, which can form covalent bonds with the hydroxyl, amino, or sulfhydryl groups present in textile fibers. The resulting reactive dye is then formulated into a preparation, often with the addition of other chemicals, to enhance its solubility, stability, and application properties.

Production inputs

The key inputs for the production of reactive dyes and preparations include organic chemicals, such as aromatic compounds, as well as inorganic salts and other additives. Specialized equipment, such as reactors, filtration systems, and drying units, are also essential for the various stages of the production process. Additionally, the industry relies on a skilled workforce with expertise in organic chemistry, process engineering, and quality control.

Production outputs

The primary output of HS code 320416 is reactive dyes and preparations, which are then consumed by the 5407 Woven fabrics of synthetic filament yarn and 5408 Woven fabrics of artificial filament yarn industries, among others. These dyes are used to impart vibrant, long-lasting colors to a wide range of textile products, contributing to the aesthetic appeal and functionality of the final goods.
