Import Tips
• Provide detailed chemical analysis proving compliance with ball-bearing steel note (h); CBP often requests verification for 52100/100Cr6 equivalents
• Measure and document exact width before rolling to confirm <300 mm; over-width shifts to broader 'other' subheadings
• Avoid rust/discoloration claims at entry per Chapter 72 note—no duty allowance for pre-entry surface oxidation
