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

HS code 400819 covers a range of vulcanized cellular rubber products, excluding those in the form of plates, sheets, or strips. This industry plays a crucial role in the broader rubber and plastics sector, providing essential materials for a wide array of applications across various industries, from automotive to construction and beyond. The versatility and unique properties of these cellular rubber products make them indispensable in many manufacturing processes, contributing to the overall growth and development of the global economy.

The production of vulcanized cellular rubber products under HS code 400819 typically involves a multi-step process. First, raw rubber materials, such as natural or synthetic rubber, are compounded with various additives, including vulcanizing agents, fillers, and other chemicals, to achieve the desired properties. The mixture is then subjected to a vulcanization process, where heat and pressure are applied to cross-link the rubber molecules, resulting in a durable and resilient material. Finally, the vulcanized rubber is shaped into the desired form, often through molding or extrusion techniques, to create the final cellular rubber products.

The main inputs required for the production of HS code 400819 products include raw rubber materials, such as natural rubber or synthetic rubber compounds, as well as various additives like vulcanizing agents, fillers, and other chemicals. Additionally, specialized machinery and equipment, such as mixing machines, vulcanization presses, and molding or extrusion systems, are essential for the manufacturing process. The availability and quality of these raw materials and production equipment play a crucial role in the industry's ability to meet the evolving demands of its customers.

The vulcanized cellular rubber products covered under HS code 400819 find applications in a wide range of industries. These materials are commonly used in the production of 401699 Rubber; vulcanized, other than hard rubber, articles n.e.s. in heading no. 4016, 401410 Rubber; vulcanized, other than hard rubber, hygienic or pharmaceutical articles, with or without fittings of hard rubber, and 401693 Rubber; vulcanized, other than hard rubber, gaskets, washers and other seals, among others.
