U.S. imports of electrical inductors (nesoi) (HS 850450) totaled $95.0M in July 2026, traded with 65 countries.
Importers of Electrical Inductors (NESOI) paid $10.3M in duties in July 2026 — an effective duty rate of 18% on $56.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataElectrical inductors — passive components that store energy in a magnetic field — serve as essential filtering and power-conditioning elements in switching power supplies, telecommunications equipment, and ADP hardware. The US schedule separates inductors for ADP and telecom applications (8504504000) from general-purpose inductors (8504508000), a distinction that affects both duty treatment and Section 301 exposure for Chinese-origin goods. The Philippines leads US import supply for this heading, reflecting significant electronics manufacturing capacity there, with Japan and China also major sources. Correct classification between the ADP/telecom-specific line and the NESOI line requires clear documentation of the inductor's intended end-use circuit.

Technical datasheets specifying the inductor's rated frequency, inductance value, and circuit application, combined with OEM purchase orders or design-in records showing use in ADP or telecommunications equipment, are the primary supporting documents. CBP may also consider whether the inductor is marketed exclusively for those applications. A binding ruling is advisable for large-volume shipments where the duty differential is material.
The Philippines hosts major contract electronics manufacturing operations for several global passive-component producers, particularly in the Laguna and Cavite economic zones. This established manufacturing base, combined with competitive labor costs and duty treatment under applicable trade frameworks, has made it the top source for inductors entering the US market.
