U.S. imports of Capacitors, Resistors, Coils, Transformers & Other Inductors (NAICS 334416) totaled $575.7M in August 2026, imported from 95 countries.
Importers of Capacitors, Resistors, Coils, Transformers & Other Inductors paid $66.7M in duties in August 2026, an average duty rate of 12.32% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataPassive electronic components — capacitors, resistors, inductors, and transformers — are high-volume, specification-driven commodities where price competition from Asian manufacturers has historically triggered antidumping investigations, particularly for ceramic capacitors and resistors. These components are classified by electrical characteristic (capacitance, resistance, inductance), dielectric or core material, and power rating, all of which determine the correct HTS subheading and applicable duty. Despite their low unit value, passive components are procurement-critical: a single out-of-spec resistor can cause field failures, making certificate-of-conformance documentation as important to buyers as customs paperwork.

For capacitors, the dielectric material (ceramic, electrolytic, film, tantalum) and capacitance value determine the applicable HTS subheading. For resistors, the type (fixed vs. variable, composition vs. wirewound) and power rating are key. Importers should obtain full technical specifications from manufacturers before classification, as a change in dielectric material or power rating can shift a product to a different subheading with a different duty rate.
Passive components are subject to periodic allocation shortages driven by demand surges in automotive and consumer electronics sectors. Long lead times from offshore manufacturers, combined with the risk of counterfeit components entering the supply chain through gray-market distributors, make supplier qualification and traceability documentation critical. Importers should verify that suppliers are on approved vendor lists and that components carry manufacturer lot traceability.
