Import Tips & Compliance
• Ensure the ingot is classified as unwrought and not as a worked product
• Provide the alloy composition to demonstrate that it meets the brass definition despite the tin and lead content
• Verify whether the tin content exceeds 3%, which would require classification as bronze instead
