HS Code for Trimmer capacitors

Trimmer capacitors are classified under HS code 8532.30, which is designated for variable or adjustable (pre-set) electrical capacitors. The classification logic is based on the component's ability to have its capacitance value modified after manufacture, typically for the purpose of fine-tuning or calibrating an electronic circuit. Unlike standard variable capacitors used for frequent user adjustment (like old radio tuning knobs), trimmer capacitors are usually adjusted only once during the assembly or maintenance process. Under Chapter 85, heading 8532 covers all electrical capacitors. The subheading 8532.30 is specifically reserved for those that are not "fixed," distinguishing them from the various fixed capacitor subheadings (8532.21 through 8532.29) based on their mechanical adjustability.

Products Included

• Ceramic trimmer capacitors
• Air dielectric trimmer capacitors
• Piston-style adjustable capacitors
• Film dielectric trimmers
• SMD (Surface Mount Device) trimmer capacitors

Common Misclassification

Trimmer capacitors are often confused with fixed capacitors classified under HS codes 8532.21 to 8532.29. The key difference is the presence of an adjustment screw or mechanism. They may also be misclassified under 8533.40 if mistaken for variable resistors (potentiometers or trimmers). It is critical to identify the component as a capacitor (storing charge) rather than a resistor (limiting current) to ensure the correct heading is applied.

FAQ

What is the HS code for Trimmer capacitors?

The HS code for trimmer capacitors, which are adjustable or pre-set capacitors, is 8532.30.

How do trimmer capacitors differ from fixed capacitors in the HS system?

Fixed capacitors have a permanent capacitance value and are classified under subheadings 8532.21-8532.29, while trimmer capacitors are adjustable and fall under 8532.30.
