Piezoelectric Quartz Crystal for Watches from China

High-precision synthetic quartz crystals engineered for use in quartz watch movements, exhibiting piezo-electric properties when subjected to mechanical stress. Classified under HTS 7104.10.00.00 as piezo-electric quartz, a synthetic precious or semiprecious stone, worked but not mounted or set. These crystals generate stable frequencies essential for timekeeping accuracy.

Import Tips

Verify piezo-electric certification and frequency specifications to confirm classification as synthetic quartz under Chapter 71

Provide lab test reports proving synthetic origin and piezo-electric properties to avoid reclassification as natural stones

Declare exact dimensions and grades; temporarily strung for transport is allowed but must not mimic mounting
