Import Tips
• Document Abbe value and dispersion properties to distinguish from lower-quality glass and support premium valuation
• Use protective shipping containers to prevent scratching, as damage could lead to rejection as 'optically worked' under customs inspection
• Declare aspheric design features if applicable to avoid confusion with simpler spherical lenses
