ERNiCrMo-3 Welding Wire
Round alloy steel welding wire with diameter 1.2 mm, containing less than 0.20% carbon, over 0.3% nickel, and molybdenum, designed for electric arc welding of nickel-chromium-molybdenum alloys. Classified under HTS 7229.90.50.08 due to its specific chemical composition and suitability for arc welding applications. Meets the criteria for low-carbon, high-nickel/molybdenum content in round wire form.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If carbon content 0.20% or higher
Exceeds low-carbon threshold, moving to general other alloy round wire without welding specification.
If presented as coated electrode wire for retail welding kits
Coated or presented as welding electrodes falls under Chapter 83 for welding preparations, not bare wire.
If supplied in angles, shapes or sections rather than round
Non-round cross-section classifies under bars/sections in heading 7228, separate from wire.

Import Tips & Compliance
• Provide mill test certificates verifying carbon <0.20%, Ni >0.3%, Mo >0.08%, and arc welding suitability to avoid reclassification
• Ensure wire diameter ≤1.6 mm is documented; common pitfall is incorrect measurement leading to higher diameter subheadings
• Certify as 'other' non-specialty alloy to prevent shifts to tool steel or high-strength categories under Chapter 72 notes
