Import Tips
• Include heat treatment records showing precipitation hardening done post-cold-rolling doesn't count as further working
• Differentiate from tool steels via U.S. note (e) element analysis in entry documentation
• Watch Section 232 tariffs on stainless; declare country of melt/pour accurately
