Import Tips
• Include fused silica purity certificates (SiO2 content) to confirm classification under glass definitions in Chapter 70
• Avoid common error of importing with protective coatings, which could classify as 'worked' under 7002.39 with absorbent layers
• Document end-use as industrial raw material to prevent misclassification as finished optical fiber under 9001
