Colour lakes; preparations based on colour lakes as specified in note 3 to this chapter

HS code 320500 covers a diverse range of color pigments and preparations known as 'color lakes'. These are essential materials used in a wide variety of industries, from paints and coatings to cosmetics and textiles. Color lakes play a crucial role in imparting vibrant, long-lasting colors to a multitude of products that are integral to modern life. As a key component of the global pigments and dyes market, this industry holds significant economic importance, with applications spanning both consumer and industrial sectors.

The production of color lakes typically involves a process of precipitating dyes or other coloring agents onto an inert substrate, such as aluminum hydroxide or calcium carbonate. This creates a stable, insoluble pigment that can be used in a wide range of formulations. The specific techniques used may vary depending on the desired color, particle size, and other performance characteristics required for the final product.

The main inputs for the color lakes industry include raw materials such as dyes, lakes, and substrates, as well as specialized production equipment like reactors, filtration systems, and drying units. Manufacturers in this industry also rely on a range of auxiliary chemicals, such as acids, bases, and dispersing agents, to optimize the properties of the final color lake products.

The primary outputs of the color lakes industry are the pigment preparations themselves, which are then consumed by a variety of downstream industries. These include the 320100 paints and varnishes, 330000 cosmetics and personal care, 590000 textiles, and 490000 printing sectors, among others. Color lakes are essential for imparting vibrant, long-lasting colors to a wide array of consumer and industrial products.
