Import Tips & Compliance

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
