Import Tips

• Verify optical material specifications and provide test certificates confirming fused silica composition to avoid misclassification as glass elements

• Ensure documentation includes proof of unmounted status; mounted lenses may shift to Chapter 90 optical instruments

• Check for anti-dumping duties on certain silica products and maintain supply chain records for origin verification
