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
