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
