U.S. exports of Variable or Adjustable (Pre-Set) Capacitors (SITC 77868) totaled $5.8M in August 2026.
Importers of Variable or Adjustable (Pre-Set) Capacitors paid $380K in duties in August 2026, an average duty rate of 12.39% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Variable or Adjustable (Pre-Set) Capacitors imports of $3.2M in August 2026 ran 19% above the year-to-date monthly average of $2.7M.
Last updated: August 2026 dataVariable and pre-set (trimmer) capacitors allow real-time or factory-set tuning of resonant circuits, making them essential in RF communications equipment, oscillators, and precision instrumentation. Unlike fixed capacitors, their mechanical or electronic adjustment mechanism is the defining classification feature, and importers should ensure product documentation clearly identifies the adjustment method to avoid misclassification. Section 301 exposure applies to units of Chinese origin, and the relatively specialized demand base means supply is concentrated among a small number of precision component manufacturers.

Both fall under this SITC heading, but the distinction matters for end-use documentation: variable capacitors are designed for repeated user adjustment (e.g., tuning dials), while pre-set trimmers are adjusted once during manufacturing or calibration and then fixed. Customs documentation and technical datasheets should specify which type is being imported to support the declared HTS subheading.
Variable and adjustable capacitors manufactured in China are subject to Section 301 tariffs. Importers sourcing from other origins should verify country-of-origin documentation carefully, as the adjustment mechanism and key subcomponents may be produced in multiple countries.
