HS-6 · Subheading
391731
Plastics; tubes, pipes and hoses thereof, flexible, having a minimum burst pressure of 27.6MPa
Heading 3917 — Tubes, pipes and hoses and fittings thereof (for example, joints, elbows, flanges), of plastics
Chapter 39: Plastics and articles thereof
Plain-language overview
Use HS-6 391731 when importing or exporting flexible plastic tubes, pipes, or hoses that have a minimum burst pressure of 27.6 MPa. For example, if you're shipping a roll of flexible PVC tubing used in high-pressure water systems, this is the correct code.
This code specifically covers flexible tubes and hoses made from plastics, distinguishing them from rigid counterparts classified under different HS codes. If you have rigid plastic pipes, you would look at HS-6 391732 instead, which pertains to those with different pressure specifications.
The 391731 classification applies to products designed for high-pressure applications, making them suitable for various industrial uses. In contrast, if your product is a non-flexible plastic pipe, you would need to refer to HS-6 391740, which covers other types of plastic pipes and fittings.
When determining the correct HS code, consider the material, flexibility, and intended use of your product. For instance, flexible hoses used in automotive applications or agricultural irrigation systems would also fall under this classification.
