Import Tips
• Distinguish from cullet (7001.00.20); provide production records showing direct fusion, not recycling
• Declare OH content levels; low-hydroxyl lumps for specific optics may need additional testing
• Avoid bulk packaging pitfalls; use vermiculite for thermal protection during sea freight
