Import Tips
• Confirm the alloy composition with a mill certificate to distinguish it from non-alloy steel fence wire, which is classified elsewhere
• Verify that the wire is not further worked into fencing products, such as barbed wire, which would change classification
• Check if the wire is subject to any import restrictions or permits for agricultural use
