About plastics; tubes, pipes and hoses thereof, flexible, having a minimum burst pressure of 27.6mpa

HS code 391731 covers the classification of flexible plastic tubes, pipes, and hoses with a minimum burst pressure of 27.6MPa. This industry plays a crucial role in the broader plastics and rubber manufacturing sector, providing essential components for a wide range of applications across various industries, including construction, automotive, and industrial equipment. The demand for these high-pressure plastic products is driven by their durability, flexibility, and cost-effectiveness compared to traditional metal alternatives.

Production process

The production of flexible plastic tubes, pipes, and hoses under HS code 391731 typically involves extrusion and molding techniques. Extrusion is the primary method, where molten plastic is forced through a die to create the desired shape and size. Depending on the specific product requirements, additional processes such as reinforcement with fibers or braiding may be incorporated to enhance the strength and pressure-bearing capabilities of the final product.

Production inputs

The main inputs required for the production of HS code 391731 items include thermoplastic resins, such as polyethylene, polypropylene, or polyvinyl chloride (PVC). These raw materials are sourced from the petrochemical industry. Additionally, specialized machinery, including extruders, molding equipment, and cutting/finishing tools, are essential for the manufacturing process. Skilled labor with expertise in plastics processing and quality control is also a critical input for this industry.

Production outputs

The primary outputs of the HS code 391731 industry are flexible plastic tubes, pipes, and hoses that are used in a variety of applications. These products may be 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 842123 Machinery; for filtering or purifying gases, among others. The versatility and durability of these flexible plastic components make them essential for a wide range of industrial, commercial, and consumer applications.
