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

HS code 3205 covers a diverse range of color lakes and preparations based on these color lakes. Color lakes are pigments that are formed by the precipitation of water-soluble dyes onto an insoluble substrate, typically aluminum hydroxide or barium sulfate. These color lakes play a crucial role in the production of a wide array of products, from paints and inks to cosmetics and food colorings, making them an essential component of many industries within the broader economy.

Production process

The production of color lakes typically involves a multi-step process. First, a water-soluble dye is selected and combined with a suitable substrate, such as aluminum hydroxide or barium sulfate. The mixture is then precipitated, often through the addition of an acid or base, to form the insoluble color lake pigment. The resulting pigment is then filtered, washed, and dried to produce the final product. Depending on the specific application, the color lakes may undergo further processing, such as milling or surface treatment, to optimize their properties.

Production inputs

The main inputs required for the production of color lakes under HS code 3205 include water-soluble dyes, insoluble substrates (such as aluminum hydroxide or barium sulfate), and various chemicals used in the precipitation and processing stages. Additionally, specialized equipment, such as reactors, filtration systems, and drying units, are necessary for the efficient production of these color lake pigments.

Production outputs

The color lakes produced under HS code 3205 are used as pigments in a wide range of industries, including 3204 Synthetic organic colouring matter and preparations based thereon as specified in note 3 to this chapter; synthetic organic products of a kind used as fluorescent brightening agents or as luminophores, whether or not chemically defined, 3212 (Pigments (including metallic powders and flakes) dispersed in non-aqueous media, in liquid or paste form, of a kind used in the manufacture of paints (including enamels); stamping foils; dyes and other colouring matter put up in forms or packings for retail sale), and 3215 Printing ink, writing or drawing ink and other inks, whether or not concentrated or solid. These color lakes are essential for the production of a diverse array of products, from paints and inks to cosmetics and food colorings.
