Import Tips
• Provide mill test certificate confirming alloy composition excludes tool steel or high-strength steel definitions
• Verify product meets 'not further worked than hot-rolled' - no polishing, coating, or cladding allowed
• Check width ≥600mm and thickness ≥4.75mm measurements at entry to avoid reclassification
