Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not reinforced and lower pressure
Unreinforced flexible tubes without high burst pressure go to other flexible subheadings.
If steel-braided with metal dominating
High-pressure hoses with significant metal components shift to Chapter 73 metal tubing.
If imported as machinery part in assembly
Articles of plastics for specific machines may classify under other plastic articles.

Import Tips & Compliance
• Include hydrostatic test reports proving 27.6 MPa burst pressure to avoid reclassification
• Declare exact polymer content; copolymers must meet 95% predominance rule from subheading notes
• Check for fittings; unattached hoses stay here, but attached may qualify for special rates per US note
