Import Tips
• Verify optical material specifications and provide certificates confirming polish quality meets unmounted optical element standards
• Include detailed technical drawings showing prism geometry and intended optical function to avoid misclassification as worked glass
• Ensure packaging prevents surface scratches, as customs inspections may reject damaged optical surfaces
