Import Tips
• Submit chemical analysis reports proving alloy status without qualifying as tool steel (US Note 72(e))
• Declare as 'in coils' explicitly; straightened products may classify under different subheadings
• Watch for rust/discoloration claims - no duty allowance per US Note 72 on pre-entry damage
