U.S. imports of Single-Layer Ceramic Dielectric Fixed Capacitors (SITC 77864) totaled $4.0M in August 2026, imported from 26 countries.
Importers of Single-Layer Ceramic Dielectric Fixed Capacitors paid $374K in duties in August 2026, an average duty rate of 9.66% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataSingle-layer ceramic capacitors (SLCCs) use a single ceramic disc or plate as the dielectric, typically formulated in Class 1 (temperature-stable, NP0/C0G) or Class 2 (high-permittivity, X7R/Z5U) dielectric types — a distinction that governs their suitability for precision RF tuning versus general decoupling applications. Their robust construction and wide operating voltage range make them common in high-voltage power electronics, RF transmitters, and military-grade circuits where multilayer ceramic capacitors (MLCCs) would be impractical. Importers should specify dielectric class and voltage rating on purchase orders, as these parameters affect both performance and the applicable HTS subheading at the 10-digit level.

Class 1 ceramics (NP0/C0G) have very stable capacitance across temperature and voltage, making them suitable for precision timing and RF circuits. Class 2 ceramics (X7R, Z5U, Y5V) offer higher capacitance per unit volume but exhibit capacitance variation with temperature, voltage, and aging — acceptable for bypass and filtering but not for precision applications. Specifying the dielectric class on import documentation helps avoid substitution errors.
Single-layer ceramic capacitors can be manufactured with much thicker dielectric layers than MLCCs, enabling voltage ratings that can reach several kilovolts — far beyond what multilayer construction typically achieves. This makes SLCCs the preferred choice for high-voltage power conversion and RF power amplifier circuits, where MLCCs would risk dielectric breakdown.
