Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If carbon content exceeds 0.20% by weight
Higher carbon alloy steel wire falls under different subheading excluding low-carbon arc welding specification.
If imported primarily as copper wire with steel core
Copper-based wire with steel reinforcement classified in Chapter 74 rather than alloy steel chapter.
If when sold as complete coated electrodes, not bare wire
Finished welding electrodes with flux coatings classified as cored wire products in Chapter 83.

Import Tips & Compliance
• Provide mill test certificates verifying carbon <0.20%, nickel >0.3%, molybdenum content, and copper plating thickness to confirm classification
• Ensure wire diameter documentation (≤1.6mm) and proof of suitability for electric arc welding, such as AWS specifications
• Avoid misclassification as carbon steel wire by highlighting alloy composition; common pitfall is incorrect carbon analysis
