Import Tips
• Certify exact alloy composition (Cr, Mo content) matching 4140 specs to confirm alloy steel status per Chapter 72 notes
• Verify cold-finishing process documentation; hot-rolled bars shift to 7228.30 headings
• Measure cross-section precisely (76-228 mm) to avoid duty shifts to smaller/larger size subheadings
