Rigid Polyphenylene Sulfide Pipe
Rigid high-temperature pipes made from polyphenylene sulfide (PPS), used for steam conveyance in factories. PPS is an engineering plastic not specifically named in other subheadings of heading 39.17, so it is classified as 'other plastics'.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pipe is flexible
Flexible pipes are classified separately from rigid ones.
If imported with fittings
Fittings are classified separately from the pipes.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Provide PPS material data sheets showing temperature and pressure ratings
• For steam use, ensure compliance with Canadian boiler and pressure vessel regulations
• Verify the pipe is rigid—flexible PPS hoses are classified elsewhere

Acrylic Rigid Tubing Cutoffs
Polymethyl methacrylate (acrylic) rigid tubing pieces shorter than 200 mm, used in aquariums, displays, and laboratory equipment. Acrylic is not a polymer of ethylene, propylene, or vinyl chloride, so it falls under 'other plastics' in this tariff item. The short length distinguishes these cutoffs from longer tubes that might be classified elsewhere.
ASA Rigid Plumbing Stubs
Acrylonitrile-styrene-acrylate (ASA) copolymer rigid stubs under 200 mm for outdoor plumbing applications. ASA is a copolymer where no single monomer unit contributes 95% or more by weight, so it is classified under 'other plastics' rather than a specific polymer subheading. These stubs are used where UV resistance and weather durability are required.
Nylon Rigid Capillary Tubes
Rigid polyamide-6 (nylon) capillary tubes under 200 mm for medical fluid transfer and instrumentation. Polyamide is not a polymer of ethylene, propylene, or vinyl chloride, so it falls under 'other plastics' in this tariff item. These fine tubes are used in precise fluid delivery systems in medical and analytical equipment.
Polypropylene Short Rigid Pipes
Short rigid pipes made from polypropylene blends where polypropylene content is below 95% by weight, used for chemical transport. Because the polypropylene content does not meet the 95% threshold, the pipe is not classified under the specific polypropylene subheading. Instead, the predominant monomer rule places it under 'other plastics' in this tariff item.
Polystyrene Rigid Straw Tubes
Rigid polystyrene tubes under 200 mm used as industrial straws or sample transport in laboratories. Polystyrene is not a polymer of ethylene, propylene, or vinyl chloride, so it falls under 'other plastics' in this tariff item. These tubes are rigid and used in various industrial and scientific applications.
Polysulfone Rigid Microtubes
Polysulfone high-temperature rigid microtubes under 200 mm for biotech filtration applications. Polysulfone is an engineering plastic that withstands high temperatures and chemical exposure, making it suitable for demanding filtration processes. It is not a polymer of ethylene, propylene, or vinyl chloride, so it falls under 'other plastics'.
