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

HS v2017 Code: 391740

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

HS code 391740 covers a wide range of plastic fittings used in various industries, including construction, plumbing, and manufacturing. These fittings, such as joints, elbows, and flanges, play a crucial role in connecting and directing the flow of liquids, gases, and other materials through pipes and hoses. The global demand for these products is driven by the growing construction and infrastructure development, as well as the increasing use of plastic materials in various applications.

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 pushing molten plastic through a die to create continuous profiles, which are then cut to the desired length and shape.

Production inputs

The main inputs required for the production of plastic fittings under HS code 391740 include thermoplastic resins, such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). These raw materials are combined with various additives, such as stabilizers, colorants, and reinforcing agents, to enhance the properties and performance of the final products. Additionally, specialized machinery, including injection molding machines and extruders, are essential for the manufacturing process.

Production outputs

The primary outputs of HS code 391740 are plastic tube, pipe, and hose fittings, which are used in a wide range of applications. These fittings are often consumed by industries such as 392010 Plastics; plates, sheets, film, foil and strip, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392290 Plastics; articles n.e.c. in heading no. 3922, and 441600 Wood; articles of wood, n.e.c., where they are used to connect and direct the flow of various materials and fluids.
