Import Tips
• Ensure the crystals are unworked (not cut into discs or wafers) to qualify for this tariff item
• Have a certificate of analysis or technical datasheet ready to confirm the chemical identity (Li2WO4) and purity
• Verify whether the goods are for industrial use, as end-use may affect applicable duties or permits
