Import Tips

Document copper deposition thickness and stainless backing specifications to distinguish from refined copper foils

Include end-user statements from refineries confirming starter sheet application in electrolytic cells

Avoid declaring as 'copper sheet' alone; specify refining function to prevent 7409 classification
