Import Tips
• Include cut angle specifications (AT-cut) and X-ray diffraction reports confirming synthetic piezo-electric quartz composition
• Avoid packaging that suggests mounting; use transport stranding only if temporarily for convenience
• Check for alloy impurities; must meet Chapter 71 note 5 purity rules for synthetic stones
