Import Tips & Compliance
• Include detailed alloy analysis reports specifying carbon 0.85-1.00% and manganese 1-1.8% to validate tool steel classification
• Declare exact dimensions as bars/rods to distinguish from plates or sheets in other headings
• Check for Section 232 tariffs on steel which may apply regardless of HTS tool steel status
