U.S. exports of Mounted Piezoelectric Crystals (HS 854160) totaled $23.1M in August 2026.
Importers of Mounted Piezoelectric Crystals paid $2.1M in duties in August 2026, an average duty rate of 14.17% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataFrequency-control precision drives the US tariff structure for mounted piezoelectric crystals, which are subdivided by oscillation frequency — from 32.768 kHz timing crystals used in real-time clock circuits all the way to quartz units exceeding 20 MHz used in RF and communications equipment. Japan is the dominant supplier, with China and Taiwan also significant sources; the concentration of quartz crystal processing in Japan reflects decades of investment in precision frequency-control manufacturing. Non-quartz piezoelectric crystals (8541600080) — including those based on lithium niobate or other materials — are classified separately and may serve specialized acoustic, sensor, or ultrasonic applications. Importers should confirm the operating frequency of quartz units at entry, as misclassification across the frequency-banded lines can affect duty liability.

The frequency-band subdivisions reflect distinct end-use markets and, historically, different duty rates tied to trade-remedy or negotiating considerations. Low-frequency units (e.g., 32.768 kHz) are primarily used in watch and RTC circuits, mid-range units (1–20 MHz) serve microcontroller and communications timing, and high-frequency units (above 20 MHz) are used in RF and precision instrumentation. Correct classification requires the manufacturer's specified nominal frequency, not a measured approximation.
CBP expects the nominal operating frequency stated on the manufacturer's datasheet or marking to determine the applicable 10-digit HTS line. Commercial invoices and packing lists should specify frequency in kHz or MHz for each line item. Where a shipment contains crystals spanning multiple frequency bands, separate line entries are required. A binding ruling from CBP can provide certainty for recurring, high-volume shipments.
