3917.33.00.00 - Other, not reinforced or otherwise combined with other materials, with fittings

HTS Code 3917.33.00.00 specifically classifies flexible tubes, pipes, and hoses made of plastics that are not reinforced or otherwise combined with other materials, and importantly, are equipped with fittings. These fittings, such as joints, elbows, or flanges, are integral to the product, enabling connection or termination of the tubing. The primary distinguishing feature of this category is the presence of these attached fittings.

This classification is distinct from its sibling category, 3917.31.00.00, which also covers flexible plastic tubing but specifies a minimum burst pressure of 27.6 MPa. It also differs from 3917.32.00, which covers similar plastic tubing but *without* any fittings. The remaining sibling, 3917.39.00, serves as a residual category for any other flexible plastic tubes, pipes, or hoses not otherwise specified.

As this HTS code represents a leaf node, there are no further subdivisions. Therefore, classification within 3917.33.00.00 relies on the definitive criteria of being a plastic tube, pipe, or hose that is not reinforced or combined with other materials and possesses attached fittings. Examples would include garden hoses with pre-attached connectors or flexible conduit with integrated couplings, all intended for fluid or air transfer.
