Import Tips & Compliance
• Confirm the membrane is designed for supercapacitor use; similar membranes for batteries may fall under 8507
• Provide specifications to CBSA
• If the membrane is part of a complete supercapacitor, classify the whole unit under 8532.10.00

Capacitor End Cap Assembly
Pre-assembled metal end caps with terminal pins used to hermetically seal electrolytic capacitors. These assemblies are essential parts of capacitors, providing electrical connection and environmental protection, and are not usable independently.
Capacitor Mounting Bracket
Stamped steel or aluminum brackets designed specifically for mounting large power capacitors to chassis. These mechanical parts are dedicated to supporting capacitors and are classified as parts of capacitors under this tariff item.
Ceramic Disc Capacitor
A fixed ceramic disc capacitor used in electronic circuits for filtering and decoupling. Although described as a part, it is a complete capacitor and is classified as a finished capacitor, not as a part of a capacitor.
Electrolytic Capacitor Spacer
Precision plastic or phenolic spacers used to separate capacitor elements inside aluminum electrolytic cans. These spacers maintain internal structure and insulation, and are essential parts of electrolytic capacitors, not usable in other applications.
Film Capacitor Metallized Film
Metallized polypropylene or polyester film rolls used as dielectric in plastic film capacitors. These semi-processed films are specifically manufactured for capacitor assembly and are essential materials, not finished capacitors.
Mica Capacitor Silver Electrode Paste
Silver-bearing conductive paste applied as electrodes on mica sheets for high-precision capacitors used in RF applications. This paste is a functional material for capacitor fabrication, not a finished capacitor or a discrete part.
