Import Tips
• Include material analysis reports proving synthetic sapphire composition to distinguish from glass or ceramic equivalents
• Label clearly as 'optical prism' with specifications to prevent reclassification as industrial ceramic under Chapter 69
• For high-value items, obtain advance rulings on 'optical element' status to mitigate customs disputes
