Rigid PE Drainage Pipe
Corrugated rigid polyethylene pipe used for stormwater and sewage drainage in construction. It qualifies under 3917.21.00.00 as a rigid tube of ethylene polymers, with HDPE providing the necessary stiffness and durability.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed for flexible/convoluted applications
Flexible or collapsible drainage hoses of ethylene classify in 3917.31, not rigid 3917.21.
If imported in coils under 38.1cm width per note
Heading 3921 free (B) rate applies only to small reservoirs/tanks; coiled narrow pipes may shift there.
If steel-reinforced for added strength
Threaded/metallic reinforced pipes fall under Chapter 73 as steel tubes, excluding pure plastic.

Import Tips & Compliance
• Conduct bend tests to document rigidity, as flexibility can lead to CBP reclassification
• Ensure documentation includes ASTM standards like F714 for PE pipe classification
