Products classified under HTS 3917.21.00.00
Rigid Polyethylene Water Pipe
A rigid tube made from high-density polyethylene (HDPE) polymers of ethylene, used for underground water distribution systems. It falls under HTS 3917.21.00.00 as a rigid pipe composed primarily of ethylene polymers (95%+ by weight), designed for fluid conveyance without flexibility.
HDPE Rigid Gas Distribution Pipe
Rigid high-density polyethylene pipe for natural gas distribution networks, meeting strict pressure ratings. Classified in 3917.21.00.00 due to its ethylene polymer base (predominant monomer) and rigid structure for buried installations.
HDPE Rigid Conduit Pipe
Rigid HDPE electrical conduit pipe for underground wiring protection. Meets 3917.21.00.00 as ethylene polymer rigid tube for structural support.
Corrugated Rigid HDPE Culvert Pipe
Large-diameter corrugated rigid HDPE pipe for highway culverts and stormwater. Rigid ethylene polymer structure places it in 3917.21.00.00.
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.
High-Pressure Rigid HDPE Tubing
Rigid HDPE tubing for high-pressure chemical transfer in industrial settings. Falls under 3917.21.00.00 for its ethylene-based polymer composition and non-flexible design.
Rigid Polyethylene Irrigation Pipe
Schedule 40 rigid PE pipe for agricultural irrigation systems, buried or above-ground. Classified in 3917.21.00.00 as rigid tubes of ethylene polymers per composition rules.
Rigid PE Pressure Pipe SDR11
Thick-walled rigid PE pipe (SDR11) for municipal water pressure lines. Ethylene polymers dominate (95%+) qualifying for 3917.21.00.00 rigid tubes.
