HS Code for Variable capacitors

Variable or adjustable (pre-set) capacitors are classified under HS code 8532.30. This classification is governed by the technical characteristics of the component, which allow for the intentional and repeated variation of its capacitance. Heading 8532 covers all electrical capacitors, whether fixed, variable, or adjustable. Subheading 8532.30 specifically targets those units where the capacitance can be tuned, either by a user (variable) or during the manufacturing/maintenance process (adjustable/trimmers). The classification follows GRI 1, as the heading text explicitly mentions variable capacitors. These components are essential in tuning circuits, such as those found in radio frequency (RF) equipment, where the resonant frequency must be adjusted. The materials used, such as air, mica, or ceramic dielectrics, do not change the primary classification as long as the device remains a variable capacitor.

Products Included

Common Misclassification

Variable capacitors are most commonly misclassified under HS code 8532.10, 8532.21, or 8532.29, which are reserved for fixed capacitors. Fixed capacitors have a set capacitance that cannot be altered. Another frequent error is classifying them under HS code 8533, which covers electrical resistors. While both are passive components, their physical properties and functions in a circuit are fundamentally different. Furthermore, if the capacitor is part of a larger assembly like a tuner module, it might be misclassified under 8529 as a part for radio transmission or reception equipment.

FAQ

What is the HS code for variable capacitors?

The HS code for variable or adjustable (pre-set) electrical capacitors is 8532.30.

What is the difference between a variable and a trimmer capacitor?

A variable capacitor is designed for frequent adjustment by the end-user (e.g., a radio tuning knob), while a trimmer (or pre-set) capacitor is intended for occasional adjustment during the calibration of a device, usually requiring a tool like a screwdriver.
