Standard International Trade Classification
U.S. imports of Electric Plugs & Sockets (Not Exceeding 1,000 Volts) (SITC 77258) totaled $331.3M in August 2026, imported from 89 countries.
Importers of Electric Plugs & Sockets (Not Exceeding 1,000 Volts) paid $40.3M in duties in August 2026, an average duty rate of 12.98% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataRated for circuits at or below 1,000 V, electric plugs and sockets are among the most volume-intensive electrical components in international trade, serving residential wiring, consumer electronics, industrial equipment, and EV charging infrastructure. Standard configuration — NEMA, IEC, BS, and other regional types — is a key commercial distinction because plugs and sockets are not universally interchangeable across markets, making origin and specification documentation critical for US importers sourcing globally. Section 301 tariffs apply to Chinese-origin goods in this category, and the high import volume from China has made tariff engineering (such as minor assembly operations in third countries) a recurring compliance concern for CBP.

CBP applies a 'substantial transformation' test: if the assembly operation in the third country is merely combining pre-formed components without meaningfully changing their character or use, the goods may still be considered Chinese-origin for tariff purposes. Substantial transformation requires a genuine change in name, character, or use. Importers using third-country assembly to manage Section 301 exposure should obtain a binding ruling or country-of-origin ruling before relying on that structure.
EV charging connectors designed for voltages at or below 1,000 V may classify here, but the classification analysis depends on the connector's rated voltage, current capacity, and whether it incorporates communication or control circuitry that could shift it to an instrument or apparatus heading. Given the rapid evolution of EV charging standards and the commercial significance of the tariff outcome, a CBP binding ruling is strongly recommended for these products.
