U.S. exports of Current-Carrying Wiring Devices (NAICS 335931) totaled $986.7M in August 2026.
Importers of Current-Carrying Wiring Devices paid $96.9M in duties in August 2026, an average duty rate of 12.10% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataManufacturers under NAICS 335931 produce the active electrical hardware — receptacles, plugs, lamp sockets, switches, dimmers, GFCI outlets, and similar devices — that carry live current within residential, commercial, and industrial electrical systems. These products sit at the intersection of electrical safety regulation and building code compliance, requiring NRTL listing under applicable UL standards before installation. Section 301 tariffs apply to many current-carrying wiring device imports from China, making origin diversification and HTS classification accuracy central concerns for importers serving the construction and renovation markets.

Current-carrying wiring devices (NAICS 335931) are designed to conduct electrical current — examples include receptacles, plugs, connectors, switches, and lamp holders. Noncurrent-carrying devices (NAICS 335932) provide mechanical support or protection without conducting current, such as conduit fittings, junction boxes, and cable trays. The distinction affects both NAICS classification of the manufacturer and, in some cases, the applicable HTS subheading for imports.
Ground-fault circuit interrupter (GFCI) and arc-fault circuit interrupter (AFCI) outlets incorporate protective electronics but are generally classified within the same HTS subheadings as standard receptacles under Chapter 85, based on their function as current-carrying wiring devices. However, the added electronic components can sometimes raise classification questions, and a binding ruling from CBP may be warranted for high-volume imports of these specialty devices.
