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

HS code 400829 covers a wide range of vulcanised rubber products, excluding hard rubber and cellular rubber. This industry plays a crucial role in the global manufacturing and transportation sectors, providing essential materials for the production of various goods, from automotive parts to industrial equipment. The versatility and durability of these rubber products make them indispensable in many industries, contributing significantly to the overall economy.

The production of vulcanised rubber products under HS code 400829 typically involves a multi-step process. The key steps include mixing raw rubber materials, such as natural or synthetic rubber, with various additives like fillers, accelerators, and vulcanizing agents. The mixture is then subjected to heat and pressure, causing the rubber to crosslink and form a durable, non-cellular structure. Depending on the desired product, the vulcanised rubber may be further processed through techniques like extrusion, molding, or calendering to achieve the final shape and form.

The main inputs required for the production of vulcanised rubber products under HS code 400829 include natural and synthetic rubber, as well as a range of chemical additives such as 380200 Activated carbon, 380610 Rosin and resin acids, and 401120 New pneumatic tyres, of rubber. Additionally, specialized machinery and equipment, such as mixing mills, extruders, and molding presses, are essential for the manufacturing process.

The vulcanised rubber products covered under HS code 400829 are used in a variety of applications, including the production of 401110 New pneumatic tyres, of rubber, 401699 Articles of vulcanised rubber, n.e.s., and 401693 Gaskets, washers and other seals, of vulcanised rubber. These rubber products are widely used in the automotive, industrial, and construction industries, contributing to the overall supply chain and economic activity.
