Import Tips
• Document the manufacturing process to show that polishing occurs before annealing, as this affects whether the glass is considered 'worked'
• Provide the exact grade and diameter specifications to confirm the under-1-mm requirement
• Keep records of the intended use as grinding media to support classification
