Import Tips
• Confirm nickel predominates by weight over iron to meet the nickel alloy definition
• Provide documentation of the cold-forming process (e.g
• cold drawing) to distinguish from hot-formed products
• Verify the bar dimensions meet the thickness-to-width ratio for bars rather than plates or sheets
