About plastics; tubes, pipes and hoses thereof, rigid, of plastics n.e.c. in heading no. 3917

HS code 391729 covers the import and export of rigid plastic tubes, pipes, and hoses that are not classified elsewhere in the 3917 heading. This industry plays a crucial role in the broader plastics and construction sectors, providing essential components for a wide range of applications, from plumbing and infrastructure to industrial equipment and consumer goods.

Production process

The production of rigid plastic tubes, pipes, and hoses typically involves extrusion, a process where molten plastic is forced through a die to create the desired shape and size. This is often followed by additional steps, such as cutting, joining, or adding fittings, to create the final product. Manufacturers may also use injection molding or rotational molding techniques, depending on the specific requirements of the application.

Production inputs

The main inputs for the 391729 industry include various types of thermoplastic resins, such as polyvinyl chloride (PVC), polyethylene (PE), or polypropylene (PP). Manufacturers also require specialized extrusion equipment, including extruders, dies, and cooling systems. Additional inputs may include fittings, connectors, and other components needed to assemble the final products.

Production outputs

The rigid plastic tubes, pipes, and hoses produced under HS code 391729 are used in a wide range of applications, including 441600 Construction, 842199 Industrial machinery, and 392010 Packaging. These products are often consumed by industries such as 230610 Agriculture, 252329 Construction materials, and 841430 HVAC equipment.
