Subheadings
Products classified under Tariff item 8532.90.00
Capacitor End Cap Assembly
> Pre-assembled metal end caps with terminal pins, designed to hermetically seal electrolytic capacitors. These assemblies are essential for the structural integrity and electrical connectivity of the capacitor, and are not usable independently.
Capacitor Mounting Bracket
> Stamped steel or aluminum brackets designed to secure large power capacitors to a chassis. These mechanical parts are shaped for specific capacitor models and are essential for mounting, thus considered parts of capacitors under heading 85.32.
Ceramic Disc Capacitor
> A fixed ceramic disc capacitor used for filtering and decoupling in electronic circuits. Although presented as a finished capacitor, it is a complete article of heading 85.32, not a part, and thus falls under the parts tariff item only if imported as a component for further assembly.
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 for the capacitor's function, thus qualifying as parts of capacitors.
Film Capacitor Metallized Film
> Metallized polypropylene or polyester film rolls used as the dielectric in plastic film capacitors for power electronics. These semi-processed films are specifically manufactured for capacitor assembly and are not usable for other purposes, making them parts of fixed 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 essential for capacitor fabrication, and is considered a part of fixed capacitors when imported for that purpose.
MLCC Internal Electrode Paste
> Nickel or copper nano-particle paste printed as internal electrodes in multilayer ceramic capacitors (MLCCs). This material is essential for the capacitor's function and is not usable independently, thus qualifying as a part of fixed capacitors.
Supercapacitor Separator Membrane
> Ultra-thin microporous membranes separating electrodes in electric double-layer capacitors (supercapacitors). These membranes are essential for the capacitor's function and are not usable for other purposes, making them parts of fixed capacitors.
Tantalum Capacitor Anode
> Tantalum anode slug or pellet used in manufacturing solid tantalum electrolytic capacitors for high-reliability applications. This anode is an essential component that is not usable independently, thus qualifying as a part of fixed capacitors.
Variable Capacitor Dielectric Trimmer
> Adjustable ceramic or air dielectric trimmers for tuning circuits in radios and transmitters. When imported disassembled, these components are parts of variable or adjustable capacitors, falling under the parts tariff item.
