Last updated: August 2026 dataMica dielectric capacitors and other fixed capacitors not covered by the more specific subheadings in heading 8532 fall here, with the US schedule offering two 10-digit lines: mica dielectric types (8532290020) and a true catch-all (8532290040). Mica capacitors are valued in high-frequency RF and precision timing circuits for their exceptional stability and low loss, making them a specialty item rather than a commodity. Japan and China are the leading suppliers, with France and Switzerland also notable — the latter two reflecting European precision-electronics manufacturing for aerospace and defense applications.

The residual line captures fixed capacitors whose dielectric material does not fit any of the named categories — tantalum electrolytic, aluminum electrolytic, single-layer ceramic, multilayer ceramic, paper/plastic film, or mica. Examples include glass dielectric, vacuum, and certain specialty polymer capacitors. Importers should work through the named subheadings systematically before defaulting to the NESOI line.
Mica itself is subject to supply-chain scrutiny because a significant share of global sheet mica is sourced from regions with documented labor concerns. While there are no US import prohibitions specific to mica capacitors, importers with ESG or forced-labor compliance programs should request supply-chain transparency documentation from manufacturers regarding the mica source. CBP's Uyghur Forced Labor Prevention Act (UFLPA) enforcement may also be relevant if any processing occurs in covered regions.
