HS v2022 Code: 400510

About rubber; unvulcanised, compounded with carbon black or silica, in primary forms or in plates, sheets or strip

HS code 400510 covers unvulcanized rubber compounds containing carbon black or silica, which are used in the production of a wide range of rubber products. This industry plays a crucial role in the global supply chain, providing essential raw materials for the manufacturing of tires, hoses, seals, and other rubber-based goods. The demand for these compounds is closely tied to the performance of the automotive, construction, and industrial equipment sectors, making it a key component of the broader economy.

Production process

The production of HS code 400510 compounds typically involves the mixing and compounding of natural or synthetic rubber with carbon black or silica fillers, as well as various additives such as accelerators, antioxidants, and vulcanizing agents. This process is carried out using specialized machinery, including Banbury mixers, two-roll mills, and extruders, to ensure a homogeneous and consistent compound. The resulting material is then typically formed into sheets, strips, or other primary shapes for further processing or distribution.

Production inputs

The main inputs required for the production of HS code 400510 compounds include natural and synthetic rubber, such as 400110 Natural rubber, in primary forms or in plates, sheets or strip, 400122 (Technically specified natural rubber (TSNR)), and 400211 (Styrene-butadiene rubber (SBR); latex). Additionally, carbon black, silica, and various chemical additives are essential components in the formulation of these compounds.

Production outputs

The primary outputs of HS code 400510 are unvulcanized rubber compounds, which are then used as inputs for the production of a wide range of rubber products. These compounds may be further processed and combined with other materials to create 401110 New pneumatic tyres, of rubber, 401220 Inner tubes, of rubber, 401693 Gaskets, washers and other seals, of vulcanized rubber other than hard rubber, and 401699 Other articles of vulcanized rubber other than hard rubber, n.e.s., among other items.
