3917.39.00 - Other

This category, HTS 3917.39.00, encompasses "Other" tubes, pipes, and hoses made of plastics, which do not fall under the more specific subheadings within 3917.3. This means it captures plastic tubing and piping that are not flexible with a minimum burst pressure of 27.6 MPa (3917.31.00.00), nor are they exclusively unreinforced or combined with other materials without fittings (3917.32.00), nor unreinforced or combined with other materials but with fittings (3917.33.00.00). Essentially, it serves as a residual category for plastic tubing and piping that has a specific construction or combination of materials that doesn't fit the preceding descriptions.

The distinction from sibling categories is crucial for accurate classification. While 3917.31.00.00 is defined by its high burst pressure, and 3917.32.00/3917.33.00.00 by the absence or presence of fittings and lack of reinforcement, 3917.39.00 is for plastic tubes, pipes, and hoses that might be reinforced or otherwise combined with materials in ways not detailed in those specific subheadings.

This "Other" category is further subdivided to provide more granular classification for specific types of plastic tubing and piping. The primary subdivision, 3917.39.00.10, addresses those tubes, pipes, and hoses that are specifically reinforced with metal. This indicates that the presence of metal reinforcement is a key distinguishing factor that warrants its own classification. The subsequent "Other" subdivision under 3917.39.00 represents any remaining plastic tubes, pipes, and hoses that are not reinforced with metal and do not fit the criteria of the other sibling categories, allowing for comprehensive coverage within the broader scope of Chapter 39.
