Rubber; vulcanised (other than hard rubber), in plates, sheets and strip of cellular rubber

HS code 400811 covers the classification of vulcanized rubber, other than hard rubber, in the form of plates, sheets, and strips of cellular rubber. This industry plays a crucial role in the broader rubber and plastics sector, providing essential materials for a wide range of applications across various industries, including automotive, construction, and consumer goods. The versatility and durability of cellular rubber make it an indispensable component in the manufacturing of a diverse array of products, contributing significantly to the global economy.

The production of cellular rubber under HS code 400811 typically involves a multi-step vulcanization process. Raw rubber is first compounded with various additives, such as fillers, accelerators, and curing agents, to enhance its physical properties. The compound is then subjected to heat and pressure, causing the rubber molecules to cross-link and form a stable, three-dimensional network. This vulcanization process transforms the raw rubber into a more durable and resilient material, which is then shaped into the desired plates, sheets, or strips through techniques like extrusion or molding.

The primary inputs required for the production of cellular rubber under HS code 400811 include natural and synthetic rubber, as well as a range of chemical additives. Machinery and equipment used in the vulcanization and shaping processes, such as extruders, presses, and molds, are also essential inputs. Additionally, the industry relies on a skilled workforce with expertise in rubber compounding, vulcanization, and product manufacturing.

The cellular rubber produced under HS code 400811 is a versatile material that finds applications in a wide range of industries. It is commonly used in the manufacture of 401110 Pneumatic tyres, new, of rubber for vehicles, as well as in the production of 401693 Gaskets, washers and other seals, of vulcanised rubber other than hard rubber, 401699 Articles of vulcanised rubber other than hard rubber, n.e.c. in heading no. 4016, and 401410 Sheath contraceptives. The industry's output contributes to the supply chain of numerous downstream sectors, supporting the overall growth and development of the global economy.
