4.0mm Heavy Alloy Steel Round Fence Wire
This is a 4.0mm round alloy steel wire designed for high-tensile fencing systems. The alloy composition provides corrosion resistance and strength beyond carbon fence wire, without reaching stainless steel composition. It is drawn to a precise diameter and is classified under tariff item 7229.90.00 as other alloy steel wire.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the wire is of non-alloy steel
Non-alloy steel wire is classified under heading 7217, not 7229, if the alloying elements do not meet the thresholds for alloy steel.
If the wire is barbed or twisted for fencing
Barbed wire and twisted wire for fencing are classified under heading 7313, not as plain wire.
If the wire is of silico-manganese steel
Silico-manganese steel has a specific subheading, and if the composition meets the defined limits, it would be classified there.

Import Tips & Compliance
• 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
