Import Tips
• Provide detailed material safety data sheets (MSDS) confirming CR-39 composition to support non-glass tariff classification
• Ensure lenses meet ANSI Z80.1 optical standards; non-compliant imports may face FDA detention
• Avoid common pitfall of declaring as 'plastic sheets' – specify ophthalmic use in commercial invoice
