• Declare intended end-use only if requested; classification based on objective characteristics like size and unworked state
• Include supplier specs confirming no post-annealing working to prevent shifts to laboratory glassware headings
• Watch for contamination with worked balls in shipments, requiring separate invoicing for compliance
