Import Tips
• Include technical datasheets proving electrical resistance and current-carrying capacity for proper 8545 classification
• Ensure invoices specify 'for electrolytic cells' to avoid default to broader carbon articles headings
• Watch for combined shipments with anodes; separate documentation prevents set classification issues
