Rigid Polyamide Fuel Line Pipe
High-strength rigid pipe from polyamide (nylon) for automotive fuel delivery systems. Falls under 3917.29.00.90 as rigid tubes of other plastics (polyamides not specifically named in ethylene/propylene/vinyl subheadings).
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If flexible polyamide hose
Flexible versions of other plastic polymers classify under 3917.32, rigidity being the key distinguisher.
If imported as part of a vehicle component assembly
Articles of plastics for specific machinery use may go to 3926 if not standalone tubes/pipes.
If specifically rigid tubes of polymers of ethylene
If ethylene monomers predominate (>95%), shifts to 3917.21 per subheading note (a)(1).

Import Tips & Compliance
• Certify polymer purity; polyamide-6,6 must meet 95% monomer threshold or classify per predominant unit per note (a)
• Provide automotive specs showing rigidity to differentiate from flexible fuel hoses
