SITCSection 7
U.S. imports of tantalum fixed capacitors (SITC 77862) totaled $10.6M in April 2026, traded with 22 countries.
Importers of Tantalum Fixed Capacitors paid $998K in duties in April 2026 — an effective duty rate of 13% on $7.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataTantalum fixed capacitors are defined by their tantalum-oxide dielectric and sintered tantalum anode, properties that deliver high capacitance density and stable performance in compact form factors — making them indispensable in aerospace electronics, medical devices, and telecommunications equipment. The tantalum supply chain carries inherent concentration risk, as the primary ore (coltan) is sourced from a limited number of regions, and US importers of finished capacitors must be aware of conflict-minerals due-diligence obligations under Dodd-Frank Section 1502 if the capacitors are destined for SEC-reporting manufacturers. Section 301 tariffs apply to Chinese-origin tantalum capacitors, reinforcing demand for supply from other manufacturing centers.

Tantalum is one of the four minerals covered by Dodd-Frank Section 1502. US publicly traded manufacturers that use tantalum capacitors in their products must conduct supply-chain due diligence and report to the SEC. Importers supplying those manufacturers are often required to provide smelter-of-origin documentation as part of their customer compliance programs.
Tantalum capacitors offer superior volumetric efficiency, lower leakage current, and better stability over temperature compared to aluminum electrolytics, making them preferred for miniaturized or high-reliability circuits. However, they are more sensitive to voltage spikes and reverse polarity, which can cause catastrophic failure — a key design consideration for engineers specifying imported components.
