U.S. imports of variable or adjustable (pre-set) capacitors (HS 853230) totaled $3.1M in June 2026, traded with 22 countries.
Importers of Variable or Adjustable (Pre-Set) Capacitors paid $382K in duties in June 2026 — an effective duty rate of 14% on $2.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Variable or Adjustable (Pre-Set) Capacitors imports of $3.1M in June 2026 ran 21% above the year-to-date monthly average of $2.5M.
Variable and pre-set adjustable capacitors serve tuning and trimming functions in RF circuits, oscillators, and precision instruments, and the US schedule divides them between mica, ceramic, or glass dielectric types (8532300010) and all other variable or adjustable capacitors (8532300090). Switzerland leads US imports under this heading — an unusual sourcing pattern that reflects the concentration of precision instrument and RF component manufacturing in Swiss and broader European industry, with Japan and Dominican Republic as secondary suppliers. The relatively narrow commercial volume of this heading belies its importance in high-value defense, aerospace, and telecommunications equipment.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Both variable (user-adjustable during operation) and pre-set (factory- or installer-adjusted, then fixed) capacitors are covered within heading 853230. The 10-digit split is by dielectric material — mica, ceramic, or glass versus all others — not by whether the capacitor is continuously variable or pre-set. The manufacturer's dielectric specification determines the correct line.
Classification of combination assemblies depends on which component imparts the essential character. If the variable capacitor is the primary functional element and the fixed capacitor is ancillary (e.g., a padding capacitor), the assembly would generally classify under 853230. If the assembly is more complex and neither element clearly dominates, GRI 3(c) or a binding ruling request from CBP may be warranted.
