Import Tips
• Provide mill test certificate confirming alloy composition meets 'other alloy steel' definition excluding tool/high-strength steel per US notes
• Verify diameter <14mm and irregular coil winding; uncoiling before import shifts to straight bar codes
• Include country-of-melt documentation to avoid Section 232 tariffs on certain steel origins
