HS v2017 Code: 400921

About rubber; vulcanised (other than hard rubber), tubing, piping and hoses, reinforced or otherwise combined only with metal, without fittings

HS code 400921 covers a crucial segment of the rubber industry, encompassing vulcanised rubber tubing, piping, and hoses that are reinforced or combined with metal, but without fittings. This product category plays a vital role in a wide range of industries, from automotive and construction to manufacturing and infrastructure development, making it an essential component of the global economy.

Production process

The production of goods under HS code 400921 typically involves a multi-step process of vulcanisation, reinforcement, and shaping. Vulcanisation is a chemical process that enhances the durability and strength of rubber, while reinforcement with metal components adds further structural integrity. The tubing, piping, and hoses are then extruded or molded into the desired shapes and sizes to meet the specific requirements of various applications.

Production inputs

The main inputs required for the production of goods under HS code 400921 include natural and synthetic rubber, metal reinforcements (such as steel or aluminum), and various chemical additives used in the vulcanisation process. Manufacturers also rely on specialized machinery and equipment, such as extruders, molding machines, and curing ovens, to ensure consistent quality and efficient production.

Production outputs

The primary outputs of the industry covered by HS code 400921 are vulcanised rubber tubing, piping, and hoses, which are then consumed by a wide range of downstream industries. These products are commonly used in 870000 Motor vehicles, trailers and semi-trailers, 842100 Machinery for the treatment of materials by a process involving a change of temperature, 460000 Manufactures of straw, of esparto or of other plaiting materials; basketware and wickerwork, and 842200 Machinery for cleaning or drying bottles or other containers; machinery for filling, closing, sealing, capsuling or labelling bottles, cans, boxes, bags or other containers; machinery for aerating beverages; dish washing machines, among others.
