Import Tips
• Include material certificates (e.g
• Schott BK7 specs) and diagrams showing blank dimensions for Customs review
• Avoid common error of calling it a 'finished lens'; stress it's a blank requiring further optical processing
• Check for any absorbent/reflecting layers per chapter notes, which could shift classification if applied
