Import Tips & Compliance
• Confirm the sheet's thickness is greater than 0.15 mm and that nickel content is at least 5% by weight
• Provide a mill test certificate showing the alloy composition to support classification
• Check if the sheet is considered 'unworked' to avoid classification as an article of another heading
