Rubber; vulcanised, thread and cord

HS code 400700 covers vulcanised rubber thread and cord, which are essential components in a wide range of industries. Vulcanised rubber is a durable and versatile material that has become indispensable in the manufacturing of various products, from automotive parts to consumer goods. This industry plays a crucial role in the global economy, supporting the operations of numerous downstream sectors and contributing to the overall growth and development of international trade.

The production of vulcanised rubber thread and cord involves a multi-step process. First, raw rubber is combined with various additives, such as sulfur and accelerators, and then subjected to a vulcanisation process. This process involves the application of heat and pressure, which cross-links the rubber molecules, resulting in a stronger and more durable material. The vulcanised rubber is then extruded or molded into the desired shape and size, creating the final thread or cord product.

The main inputs required for the production of vulcanised rubber thread and cord include 400110 Natural rubber, in primary forms or in plates, sheets or strip and 400220 (Butadiene rubber (BR)) as the primary raw materials. Additionally, the industry relies on various chemicals, such as sulfur and accelerators, as well as specialized machinery and equipment for the vulcanisation and extrusion processes.

The primary outputs of HS code 400700 are vulcanised rubber threads and cords, which are then used as inputs in the production of a wide range of products. These include 401110 New pneumatic tyres, of rubber for the automotive industry, 401310 Inner tubes, of rubber for various transportation applications, and 560721 Twine, cordage, ropes and cables, of sisal or other textile fibres of the genus Agave, not electrically insulated for industrial and consumer applications.
