Import Tips
• Confirm the crystals are not cut or shaped as optical elements, which would move them to Chapter 90
• Declare the chemical purity and crystalline form on the commercial invoice
• If the crystals are doped for laser use, ensure the doping does not introduce organic components that could affect classification
