About rubber; inner tubes, n.e.c. in heading no. 4013

HS code 401390 covers a wide range of rubber inner tubes used in various applications. These inner tubes are essential components in the transportation and logistics industries, providing crucial support and protection for vehicle tires. As a key part of the broader rubber manufacturing sector, the production and trade of these inner tubes play a significant role in the global economy, facilitating the movement of goods and people across borders.

Production process

The production of rubber inner tubes typically involves a multi-step process. First, raw rubber materials, such as natural or synthetic rubber, are compounded with various additives to achieve the desired properties. The rubber compound is then extruded or molded into the shape of the inner tube, often with reinforcing layers of fabric or steel. Finally, the inner tube is cured or vulcanized, a process that cross-links the rubber molecules to improve its strength, durability, and resistance to heat and chemicals.

Production inputs

The main inputs required for the production of rubber inner tubes include raw rubber materials, such as 400110 natural rubber and 400220 synthetic rubber, as well as reinforcing materials like fabric or steel. Additionally, the manufacturing process requires specialized machinery, such as extruders, molding equipment, and vulcanization presses. Other important inputs include various chemical additives, such as accelerators, antioxidants, and vulcanizing agents, which are used to enhance the inner tube's performance characteristics.

Production outputs

The primary output of HS code 401390 is rubber inner tubes, which are used in a wide range of applications, including 401110 new pneumatic tires, of rubber and 401120 retreaded or used pneumatic tires, of rubber. These inner tubes are essential components in the transportation and logistics industries, as they provide the necessary support and protection for vehicle tires. The output of this industry may also be consumed by other related industries, such as 401699 articles of vulcanized rubber n.e.c., other than hard rubber.
