Last updated: July 2026 dataLow-voltage fuses — the sacrificial overcurrent protection elements used in consumer electronics, appliances, automotive systems, and industrial control panels operating at or below 1,000 V — are widely traded components with broad end-use reach. Product distinctions that matter at classification include current rating, interrupting capacity, physical form factor (cartridge, blade, resettable), and whether the fuse is a discrete component or part of a fuseholder assembly. Goods originating in China may be subject to Section 301 tariffs, and importers should verify whether any product-specific exclusions remain active.

A fuseholder presented separately from fuses generally classifies as an electrical connector or accessory rather than as a fuse. When fuses and holders are imported together as a set, classification follows the component that gives the set its essential character — typically the fuse itself — but the specific configuration and packaging matter. Consulting a licensed customs broker is recommended for combination shipments.
Resettable PTC (positive temperature coefficient) devices function as overcurrent protectors but may be classified differently from conventional one-time fuses depending on their construction and the applicable tariff schedule notes. Importers should review the technical description carefully and consider a binding ruling if the device's classification is not clearly established.
