3917.29.00.90 - Other

This HTS classification, 3917.29.00.90, pertains to rigid tubes, pipes, and hoses made from plastics, excluding those specifically defined by other subheadings within the "Of other plastics" category. The key defining characteristic for inclusion here is that the plastic material used does not fall under the specific plastic types enumerated in preceding subheadings (e.g., polyvinyl chloride, polyethylene, polypropylene). These items are typically rigid, manufactured through extrusion or similar processes, and intended for the conveyance of fluids or other substances.

Distinguishing this category from its sibling, 3917.29.00.50, is primarily based on the length of the article. While 3917.29.00.50 specifically covers rigid plastic tubes, pipes, and hoses of other plastics that are less than 200 millimeters in length, this subheading, 3917.29.00.90, encompasses all other rigid plastic tubes, pipes, and hoses of other plastics that do not meet the length criteria of the sibling category. Therefore, items exceeding 200 millimeters in length, or those where length is not a distinguishing factor, would generally fall under this "Other" category.

As this is a leaf node within the HTS classification structure, there are no further subcategories to introduce. The classification is complete at this level based on the material composition (other plastics) and the physical form (rigid tubes, pipes, or hoses) that do not fit into more specific preceding categories. When classifying items under this subheading, thorough examination of the plastic composition and confirmation that the item is rigid and fits the description of a tube, pipe, or hose is crucial.
