Rigid Polycarbonate Air Duct Pipe
Rigid tubing from polycarbonate plastic for HVAC air distribution systems. It qualifies under HTS 3917.29.00.90 for rigid pipes of other plastics, used to convey air in ventilation setups.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the duct pipe is flexible or semi-rigid
Flexible plastic hoses/pipes for air conveyance shift to 3917.39, based on physical bend test standards.
If sold as reservoirs or containers for liquids rather than conveyance
Rigid plastic tanks/reservoirs classify under 3925.10 if primary function is storage, not flow-through piping.
If made of glass fibers reinforced with minimal plastic
Glass-reinforced plastic composites may fall under Chapter 70 if glass predominates, changing material heading.

Import Tips & Compliance
• Include material safety data sheets (MSDS) proving polycarbonate composition and rigidity for customs verification
• Document end-use as conveyance (air) to prevent misclassification as duct fittings
