Import Tips
• Provide mill test certificate confirming alloy steel composition (e.g
• Cr 0.8-1.1%, Mo 0.15-0.25%) excluding tool steel elements
• Declare exact width (<600mm) and confirm not further worked beyond cold-rolling to avoid reclassification
• Watch Section 232 tariffs; ensure melt-and-pour documentation if derivative aluminum/steel aluminum product claims apply
