U.S. imports of electrical control and distribution boards, panels, and consoles for voltage not exceeding 1,000 v (HS 853710) totaled $2.0B in May 2026, traded with 99 countries.
Importers of Electrical Control and Distribution Boards, Panels, and Consoles for Voltage Not Exceeding 1,000 V paid $134.4M in duties in May 2026 — an effective duty rate of 14% on $932.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Electrical Control and Distribution Boards, Panels, and Consoles for Voltage Not Exceeding 1,000 V imports of $2.0B in May 2026 ran 13% above the year-to-date monthly average of $1.8B.
Last updated: May 2026 dataSwitchgear assemblies, switchboards, motor control centers, panel boards, programmable controllers, and numerical controls for machine tools all classify within this heading when equipped with electrical apparatus and rated at or below 1,000 V. The US schedule is unusually granular, with thirteen 10-digit tariff lines that separately enumerate motor control centers (8537106000), touch screens without displays (8537108000), programmable controllers (8537109060/8537109160), and numerical controls for machine tools (8537109030/8537109130), among others — making product-function documentation critical at entry. Mexico and Canada together dominate import supply, reflecting deep North American integration in industrial electrical equipment manufacturing; USMCA origin qualification is a significant duty-planning lever for goods assembled in either country. Chinese-origin goods under this heading carry Section 301 exposure, and the complexity of the line structure means classification errors are common for multi-function control panels.

Numerical controls (CNC) under 8537109030 are purpose-built to direct the motion axes and tool functions of machine tools such as lathes, mills, or grinders. Programmable logic controllers (PLCs) under 8537109060 are general-purpose sequential control devices used across a wide range of industrial automation applications beyond machine tools. The intended application and programming architecture are the primary classification criteria; a CNC that also performs PLC functions may require a binding ruling.
USMCA origin for goods in heading 8537 is determined by the applicable tariff shift rule and, in some cases, a regional value content requirement. Assembly in Mexico does not automatically confer USMCA origin if the Chinese-origin components do not undergo a qualifying tariff classification change. A detailed origin analysis by a licensed customs broker or trade attorney is necessary before claiming USMCA preference.
