HC-49S Quartz Crystal 3.579545 MHz from Japan
The HC-49S is a through-hole quartz crystal resonator designed for frequencies like 3.579545 MHz, used in consumer electronics such as TV tuners and older computer clocks. It falls under HTS 8541.60.00.20 as a mounted piezoelectric quartz crystal operating below 1 MHz (excluding 32.768 kHz watch crystals). These are precision-tuned for stable oscillation in RF circuits.

Import Tips
• Verify frequency certification (e.g
• 3.579545 MHz) and exclude 32.768 kHz to confirm HTS 8541.60.00.20 classification
• Include manufacturer specs showing mounted quartz construction and operating frequency in import documentation
• Avoid misclassification as unmounted crystals (8541.60.0060) by proving hermetic sealing and electrode mounting
