Import Tips
• Obtain FDA establishment registration and device listing for ophthalmic products, as spectacle lenses are Class 1 medical devices
• Provide certificates of optical quality and material composition to verify glass content and avoid misclassification as plastic lenses
• Declare exact diopter power and base curve on commercial invoice to prevent reclassification during customs examination
