HS-6 · Subheading
391721
Plastics; tubes, pipes and hoses thereof, rigid, of polymers of ethylene
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 391721 when importing or exporting rigid tubes and pipes made from polymers of ethylene. For example, a shipment of rigid plastic pipes used in plumbing systems falls under this code.
This code specifically applies to rigid tubes and pipes, distinguishing them from flexible options found under related codes like 391722, which covers flexible tubes and hoses. If your product is a rigid plastic pipe for construction, this is the correct classification.
These products are typically used in various applications, including plumbing, irrigation, and industrial processes. They are often sold in lengths and can be used for transporting liquids or gases.
If you’re dealing with fittings or joints, you’ll want to look at other codes within the same heading, as they cover different components. Rigid tubes and pipes are primarily for direct transport, while fittings serve as connectors.
