Rigid Fluoropolymer Tubes
Rigid PVDF (polyvinylidene fluoride) tubes under 200 mm for corrosive chemical handling. PVDF is a fluoropolymer that offers excellent chemical resistance and is not a polymer of ethylene, propylene, or vinyl chloride. It falls under 'other plastics' in this tariff item due to its specific polymer composition.

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 plates, sheets, or film rather than tubes
Fluoropolymer in flat form is classified under heading 3920, not as tubes under 3917.

Import Tips & Compliance
• Clearly identify the polymer as PVDF to avoid confusion with other fluoropolymers
• Provide technical data sheets showing chemical resistance properties
• Ensure the tubes are rigid and under 200 mm in length for this classification

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'.
