3917.32.00.20 - Of polyethylene

This HTS category, 3917.32.00.20, specifically classifies tubes, pipes, and hoses, as well as their fittings, made of plastics. The focus here is on articles that are not reinforced or otherwise combined with other materials, and importantly, are not equipped with fittings. This exclusion of fittings is a key characteristic that differentiates them from other categories within the broader scope of plastic tubes, pipes, and hoses.

Within this specific sub-heading, 3917.32, which covers "Other tubes, pipes and hoses," the code 3917.32.00.20 further refines the classification to those *of polyethylene*. This directly distinguishes it from its sibling category, 3917.32.00.10, which is designated for articles made of polyvinyl chloride. The material composition is the primary differentiating factor at this level of detail.

As this is a leaf node, there are no further subcategories. Therefore, the classification of an item under 3917.32.00.20 hinges on the determination that it is a plastic tube, pipe, or hose, not reinforced or combined with other materials, lacking fittings, and primarily manufactured from polyethylene. Examples would include simple polyethylene tubing used for general purposes, fluid transfer, or as protective conduits, provided they meet all the outlined criteria.
