HS v2017 Code: 391721

About plastics; tubes, pipes and hoses thereof, rigid, of polymers of ethylene

HS code 391721 covers the production and trade of rigid plastic tubes, pipes, and hoses made from polymers of ethylene. This industry plays a crucial role in the broader plastics and packaging sectors, providing essential components for a wide range of applications across various industries. The demand for these products is driven by their durability, versatility, and cost-effectiveness, making them indispensable in sectors such as construction, automotive, and industrial manufacturing.

Production process

The production of rigid plastic tubes, pipes, and hoses under HS code 391721 typically involves extrusion, a process where molten polymer is forced through a die to create the desired shape and size. This process allows for the continuous manufacturing of these products, ensuring consistent quality and efficiency. Additionally, techniques such as injection molding and blow molding may be employed to create more complex or specialized shapes and designs.

Production inputs

The main inputs required for the production of HS code 391721 products include polymers of ethylene, such as polyethylene (PE) and high-density polyethylene (HDPE), as well as various additives and stabilizers to enhance the properties of the final products. Additionally, specialized machinery and equipment, such as extruders, dies, and cooling systems, are essential for the manufacturing process.

Production outputs

The rigid plastic tubes, pipes, and hoses produced under HS code 391721 are widely used in a variety of applications, including 392010 Plastics; plates, sheets, film, foil and strip, of polymers of ethylene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392020 Plastics; plates, sheets, film, foil and strip, of polymers of propylene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, and 392030 Plastics; plates, sheets, film, foil and strip, of polymers of styrene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials. These products are essential components in industries such as construction, plumbing, and industrial manufacturing.
