Import Tips
• Declare load capacitance and frequency tolerance specs to demonstrate compliance with mounted crystal requirements
• Use ESD-safe shipping containers; US Customs often inspects electronics for static damage claims
• Avoid classifying as 'oscillator modules' if just the crystal—complete assemblies with ICs go to 8542.39
