HS v2022 Code: 391740

About plastics; tube, pipe and hose fittings (e.g. joints, elbows, flanges)

HS code 391740 covers a diverse range of plastic fittings used in various industries, including construction, plumbing, and manufacturing. These components play a crucial role in connecting and managing the flow of liquids, gases, and other materials through piping systems. The global demand for these products is driven by factors such as infrastructure development, industrial growth, and the need for efficient fluid transportation and distribution.

Production process

The production of plastic tube, pipe, and hose fittings typically involves injection molding or extrusion processes. In injection molding, molten plastic is injected into a mold cavity, where it cools and solidifies into the desired shape. Extrusion, on the other hand, involves continuously forcing molten plastic through a die to create a continuous profile, which is then cut to the desired length. Both techniques allow for the mass production of these fittings, ensuring a consistent quality and a wide range of sizes and configurations.

Production inputs

The main inputs required for the production of plastic fittings include thermoplastic resins, such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). These raw materials are sourced from the petrochemical industry. Additionally, manufacturers may use various additives, such as stabilizers, colorants, and reinforcing agents, to enhance the performance and appearance of the final products. Specialized production equipment, including injection molding machines and extruders, are also essential inputs for this industry.

Production outputs

The primary outputs of HS code 391740 are a diverse range of plastic fittings, including joints, elbows, flanges, and other connectors. These components are used in a wide variety of applications, such as 392321 Plastics; sacks and bags, including cones, 392410 Plastics; tableware and kitchenware, and 392490 Plastics; other household articles and hygienic or toilet articles. The outputs of this industry are often consumed by other manufacturing sectors, such as construction, plumbing, and industrial equipment, where they are used to assemble and maintain various piping systems.
