Organo-sulphur compounds; thiuram mono-, di- or tetrasulphides

HS code 293030 covers a group of organo-sulphur compounds known as thiuram mono-, di- or tetrasulphides. These compounds play a vital role in the production of various rubber and plastic products, serving as accelerators and vulcanizing agents. They are essential in the manufacturing of tires, hoses, seals, and other rubber-based industrial and consumer goods. The global demand for these organo-sulphur compounds is driven by the growth of the automotive, construction, and consumer goods industries, making this code an important part of the broader chemical and materials sector.

Thiuram mono-, di- or tetrasulphides are typically produced through a multi-step chemical synthesis process. The key steps involve the reaction of an amine compound, such as dimethylamine or diethylamine, with carbon disulfide to form a dithiocarbamate intermediate. This intermediate is then further reacted with sulfur or a sulfur-containing compound to form the final thiuram product. The specific production techniques may vary depending on the desired composition and properties of the final organo-sulphur compound.

The main inputs required for the production of HS code 293030 products include amine compounds, carbon disulfide, and sulfur or other sulfur-containing chemicals. Additionally, specialized production equipment, such as reactors, distillation columns, and purification systems, are necessary to ensure the quality and consistency of the final products. The availability and cost of these raw materials and production resources can significantly impact the overall competitiveness of this industry.

The primary outputs of HS code 293030 are thiuram mono-, di- or tetrasulphides, which are then used as key ingredients in the manufacturing of various rubber and plastic products. These organo-sulphur compounds are often consumed by industries producing 400211 (Styrene-butadiene rubber (SBR)), 400122 (Butadiene rubber (BR)), 400129 Other synthetic rubber, and 3902 Polymers of propylene or other olefins, among others. The versatility of these compounds in enhancing the properties of rubber and plastic materials makes them an essential component in the broader chemical and materials supply chain.
