Plastics; tubes, pipes and hoses thereof, rigid, of polymers of vinyl chloride

HS v2022 Code: 391723

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

HS code 391723 covers the production of rigid plastic tubes, pipes, and hoses made from polymers of vinyl chloride. 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 drainage systems to industrial and agricultural uses, these rigid plastic products are in high demand globally, making this a significant segment of the international trade landscape.

Production process

The production of rigid vinyl chloride polymer tubes, pipes, and hoses typically involves extrusion. In this process, the raw polymer material is heated and forced through a die to create the desired shape and size of the final product. Specialized equipment, such as extruders and calibration tools, are used to ensure consistent dimensions and quality. Post-extrusion steps may include cutting, cooling, and surface finishing to meet specific customer requirements.

Production inputs

The main inputs for this industry include 390410 Polymers of vinyl chloride or of other halogenated olefins, in primary forms, as well as various additives such as stabilizers, plasticizers, and colorants. Manufacturers also require access to specialized extrusion machinery and tooling. Energy sources, such as electricity or natural gas, are necessary to power the production process.

Production outputs

The primary outputs of HS code 391723 are rigid plastic tubes, pipes, and hoses made from vinyl chloride polymers. These products are widely used in 441600 Prefabricated buildings, 441700 Builders' joinery and carpentry of wood, and 442100 Furniture; parts thereof, as well as in plumbing, irrigation, and industrial applications. The outputs of this industry may also be further processed or incorporated into other 392000 Plastics and articles thereof, 681100 Articles of asbestos-cement, of cellulose fibre-cement or the like, or 731500 Chain and parts thereof, of iron or steel products.
