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
