HS v2022 Code: 320414
About dyes; direct dyes and preparations based thereon
HS code 320414 covers the import and export of direct dyes and preparations based on these dyes. Direct dyes are a class of synthetic colorants that are widely used in the textile industry to dye natural and synthetic fibers. They are known for their ease of application, good colorfastness, and versatility in dyeing a wide range of materials. The direct dyes industry plays a crucial role in the global textile supply chain, supporting the production of apparel, home furnishings, and industrial textiles that are in high demand worldwide.
Production process
The production of direct dyes typically involves a multi-step chemical synthesis process. This often begins with the preparation of an intermediate compound, which is then further reacted and modified to create the final dye product. Key steps may include diazotization, coupling reactions, and purification processes to ensure the desired color, strength, and quality characteristics. Manufacturers utilize specialized equipment and carefully controlled conditions to optimize the yield and performance of the direct dyes.
Production inputs
The main inputs required for the production of direct dyes include various organic chemicals, such as aromatic amines, phenols, and other intermediates. Manufacturers also rely on access to reliable sources of energy, water, and other utilities to power the production facilities. Specialized machinery, including reactors, filtration systems, and drying equipment, is essential for the efficient and consistent manufacture of direct dyes to meet industry standards.
Production outputs
The primary output of HS code 320414 is direct dyes, which are then consumed by the 500320 Textile Dyeing and Finishing Industry for coloring a wide range of textile products. Direct dyes may also be used in other applications, such as 320416 Reactive dyes and preparations based thereon or 320417 Pigments and preparations based thereon, depending on the specific properties and requirements of the end-use industry.
