Last updated: April 2026 dataReplacement and OEM components for switching, protecting, and connecting electrical circuits—such as contact assemblies, arc-chute parts, and actuator mechanisms—are captured here when they don't qualify under a more specific parts provision. Correct classification requires confirming both that the part is dedicated to apparatus of the switching/protection family and that no more specific parts heading applies. Supply chains for these components are often deeply integrated with electronics manufacturing hubs, and parts sourced from certain origins may carry Section 301 exposure that differs from the finished apparatus they support.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
When a part performs multiple functions, classification typically follows the component's principal function or the apparatus it is primarily designed to be used with. If the principal function cannot be determined, the heading that occurs last in numerical order among the competing provisions generally applies under GRI 3(c) logic—though a binding ruling is advisable for recurring ambiguous parts.
Yes. Parts and finished apparatus are classified separately based on their individual descriptions, even when shipped together. Importers should ensure the commercial invoice itemizes parts and finished goods distinctly, with separate line values, to avoid misclassification and potential penalties.
