Import Tips
• Label with exact steel alloy (e.g
• 316SS) and certify as forged, not cast, to distinguish from 7325 castings
• Avoid common pitfall of shipping with minor machining, which reclassifies to 8481.90.10 or other headings
• For high-value semi uses, obtain advance ruling on 'part of valve' specificity to prevent Chapter 73 shifts
