Dyes; synthetic organic products of a kind used as fluorescent brightening agents

HS v2017 Code: 320420

About dyes; synthetic organic products of a kind used as fluorescent brightening agents

HS code 320420 covers a crucial segment of the chemical industry, encompassing the production of synthetic organic dyes and fluorescent brightening agents. These products play a vital role in a wide range of industries, from textiles and paper manufacturing to plastics and cosmetics. As a key component in the global supply chain, the 320420 industry contributes significantly to the broader economy, enabling the creation of vibrant, eye-catching, and functional products that consumers demand.

Production process

The production of dyes and fluorescent brightening agents under HS code 320420 typically involves a multi-step chemical synthesis process. This often begins with the extraction and purification of raw materials, such as organic compounds and petrochemicals. These are then subjected to a series of reactions, including condensation, diazotization, and coupling, to create the desired dye or brightening agent molecules. Advanced techniques, such as chromatography and crystallization, are employed to ensure the purity and consistency of the final products.

Production inputs

The 320420 industry relies on a range of raw materials and resources, including 271011 Petroleum oils and oils obtained from bituminous minerals, other than crude, 290000 Organic chemicals, and various specialty chemicals. Additionally, the industry requires specialized production equipment, such as reactors, distillation columns, and filtration systems, as well as a skilled workforce capable of operating these complex processes.

Production outputs

The primary outputs of the 320420 industry are synthetic organic dyes and fluorescent brightening agents, which are then consumed by a variety of downstream industries. These include 500000 Textile fibers, 470000 Paper and paperboard; articles of paper pulp, of paper or of paperboard, and 390000 Plastics and articles thereof, among others. The versatility of these products allows them to be incorporated into a wide range of consumer and industrial applications, contributing to the vibrant and functional products that are essential to modern life.
