Import Tips
• Provide detailed optical specifications and material composition certificates to verify classification under 9001.90.40.00
• Avoid common pitfalls by ensuring lenses are truly unmounted; assembled units may shift to Chapter 90 finished instruments
• Comply with FDA regulations if lenses are for medical devices, even if imported as components
