Colouring matter; ultramarine and preparations based thereon

HS v2017 Code: 320641

About colouring matter; ultramarine and preparations based thereon

HS code 320641 covers the production and trade of ultramarine and preparations based on this colouring matter. Ultramarine is a vibrant blue pigment that has been used for centuries in various applications, from fine art to industrial coatings. As a key input for a wide range of industries, the ultramarine market plays a significant role in the global economy, with applications spanning the textile, paper, plastics, and cosmetics sectors.

Production process

The production of ultramarine involves a complex process of calcination, reduction, and oxidation. Firstly, a mixture of sodium sulfate, sulfur, and charcoal is heated to high temperatures, causing the sulfur to react with the sodium to form sodium polysulfides. This compound is then combined with clay and other additives, and the mixture is further heated and processed to produce the desired ultramarine pigment.

Production inputs

The main inputs required for the production of ultramarine and related preparations under HS code 320641 include sodium sulfate, sulfur, charcoal, and various clay materials. Additionally, specialized equipment such as high-temperature furnaces and mixing/processing machinery are essential for the manufacturing process.

Production outputs

The primary output of HS code 320641 is ultramarine pigment, which is then used as a colouring agent in a wide range of products, including paints, inks, plastics, and cosmetics. Other outputs may include preparations based on ultramarine, such as ultramarine-containing coatings or dispersions. These outputs may be consumed by industries classified under various other HS codes, such as 3204 Synthetic organic colouring matter, 3206 Other colouring matter; preparations, and 3208 Paints and varnishes, among others.
