About rubber; inner tubes, of a kind used on bicycles

HS code 401320 covers the import and export of rubber inner tubes used on bicycles. This industry plays a crucial role in the broader transportation and logistics sectors, providing essential components for one of the most widely used modes of personal transportation globally. The demand for these inner tubes is driven by the growing popularity of bicycling for both recreational and commuting purposes, making this a significant area of international trade.

Production process

The production of rubber inner tubes for bicycles typically involves a multi-step process. First, natural or synthetic rubber is compounded with various additives to achieve the desired physical properties. The rubber compound is then extruded or molded into the shape of the inner tube, with careful attention paid to the thickness and flexibility of the material. Finally, the inner tube is vulcanized, a process that cross-links the polymer chains to improve durability and resistance to punctures.

Production inputs

The main inputs required for the production of bicycle inner tubes include natural or synthetic rubber, as well as various reinforcing agents, such as carbon black or silica. Additionally, specialized machinery for extrusion, molding, and vulcanization is necessary to ensure consistent quality and performance of the final product. The availability and cost of these raw materials and equipment can significantly impact the competitiveness of this industry in the global market.

Production outputs

The primary output of HS code 401320 is rubber inner tubes for bicycles. These inner tubes are essential components for the 871200 (Bicycles and other cycles (including delivery tricycles), not motorized) industry, as they provide the necessary air-filled cushioning and support for the wheels.
