U.S. imports of parts for electrical circuit apparatus and control or distribution boards (nesoi) (HS 853890) totaled $389.3M in April 2026, traded with 81 countries.
Last updated: April 2026 dataPrinted circuit assemblies, molded parts, electrical metal contacts, automatic circuit breaker parts, and switchgear parts for apparatus in headings 8535, 8536, and 8537 all fall within this broad parts heading. The US schedule is highly detailed, with twelve 10-digit lines that distinguish printed circuit assemblies (8538901000, 8538903000), non-PC assemblies (8538904000), molded parts (8538906000), circuit breaker parts (8538907020/8538908120), metal contacts (8538907040/8538908140), and switchgear parts (8538907060/8538908160), among others. Mexico leads import supply, with China and Germany also significant — and Chinese-origin goods are subject to Section 301 tariffs. Correct classification requires identifying both the part type and the specific parent apparatus heading (8535, 8536, or 8537) for which the part is suitable.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Parts that are solely or principally suitable for use with apparatus in headings 8535, 8536, or 8537 classify under 8538 per the General Rules of Interpretation and the relevant chapter notes. If a part is equally suitable for apparatus in multiple headings, the importer should identify the primary intended use. Parts with broader applicability — such as generic fasteners or standard electronic components — may classify elsewhere under their own headings.
CBP may request technical datasheets confirming the contact material (typically silver, gold, or copper alloy), contact geometry, and the specific apparatus (circuit breaker, relay, contactor) for which the contacts are designed. A supplier declaration or engineering specification linking the contacts to apparatus in headings 8535–8537 strengthens the classification position and reduces the risk of reclassification to a base-metal parts heading.
