Import Tips
• Declare exact width and thickness with gauged certificates; products under 600mm width classify under 7226
• Confirm alloy status via chemical analysis reports to distinguish from stainless (73xx) or tool steel notes
• Watch for rust/discoloration claims—Chapter note denies duty reductions for pre-entry damage on steel products
