Import Tips & Compliance
• Ensure the blank is not optically worked, as lithography lenses are often finished in Chapter 90
• Document the fused quartz composition to confirm it is 'glass' per Chapter 70 note 5
• Be aware that if the blank is for a specific lithography machine, it may be considered a part of Chapter 90 equipment
