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'.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the tubes are made of PVC
PVC tubes are classified under 3917.23, not under 'other plastics'.
If the goods are finished articles rather than tubes
Finished plastic articles are classified under heading 3926, not as tubes under 3917.

Import Tips & Compliance
• Provide the polymer name (polysulfone) and its specifications to CBSA
• If the microtubes are for medical or biotech use, additional regulatory approvals may be needed
• Ensure the tubes are rigid and under 200 mm in length

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.
Rigid ABS Drain Pipe
Rigid ABS drain pipe for wastewater drainage in residential plumbing. ABS is a copolymer of acrylonitrile, butadiene, and styrene; because no single monomer unit contributes 95% or more by weight, it is classified as a rigid pipe of other plastics under this tariff item.
