3917.32.00 - Other, not reinforced or otherwise combined with other materials, without fittings

This classification covers flexible tubes, pipes, and hoses made from plastics that are neither reinforced nor combined with other materials, and importantly, are not fitted with any joints, elbows, flanges, or other connecting pieces. The "other" designation signifies that these items do not meet the specific criteria for minimum burst pressure or the presence of fittings.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike 3917.31.00.00, these tubes, pipes, and hoses do not have a specified minimum burst pressure of 27.6 MPa. Furthermore, they are distinct from 3917.33.00.00, which includes similar unreinforced plastic tubing but possesses fittings, and from 3917.39.00, which encompasses all other plastic tubes, pipes, and hoses not otherwise specified.

Within this category, further subdivisions are made based on the specific type of plastic used. The subcategories for polyvinyl chloride (3917.32.00.10) and polyethylene (3917.32.00.20) allow for more precise identification of common plastic materials. The "other" subcategory (3917.32.00.50) is reserved for tubing made from plastic materials not specifically listed in the preceding subcategories, ensuring comprehensive coverage for a wide range of plastic compositions.
