HS v2022 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 various sectors, including construction, manufacturing, and infrastructure development. Ethylene-based plastics are valued for their durability, chemical resistance, and versatility, making them a popular choice for a wide range of applications.

Production process

The production of rigid plastic tubes, pipes, and hoses under HS code 391721 typically involves extrusion, a process where molten plastic is forced through a die to create the desired shape and size. This process allows for the continuous production of consistent, high-quality products. Depending on the specific application, additional steps such as cutting, joining, or surface treatment may be employed to meet the required specifications.

Production inputs

The main inputs for the production of HS code 391721 items include ethylene-based polymers, such as polyethylene (PE) and ethylene-vinyl acetate (EVA), as well as various additives and colorants. Specialized machinery, including extruders, cooling systems, and cutting equipment, are also essential for the manufacturing process. Energy, labor, and transportation are other significant inputs required for this industry.

Production outputs

The primary outputs of HS code 391721 are rigid plastic tubes, pipes, and hoses, which are used in a wide range of applications. These products may be further processed or incorporated into 392010 Plastics; plates, sheets, film, foil and strip, of polymers of ethylene, 392020 Plastics; plates, sheets, film, foil and strip, of polymers of propylene, or 392030 Plastics; plates, sheets, film, foil and strip, of polymers of styrene, depending on the specific requirements of the end-user industries.
