South Korea and China are the leading import sources, and both countries' products may be subject to antidumping or countervailing duty orders on welding wire in addition to Section 232 tariffs.

Yes. The US schedule includes a dedicated line (7217304504) for round wire with less than 0.20% carbon plated with base metal and intended for arc welding, distinguishing it from general-purpose base-metal-plated wire. Importers of welding wire should confirm whether their product meets the arc-welding specification to use this line rather than a broader NESOI line.
Both South Korea and China have been named in antidumping and countervailing duty proceedings on certain steel welding wire products. In addition to Section 232 tariffs, importers should consult the current USITC and Commerce Department order lists and any applicable scope rulings to determine the full duty stack before committing to a sourcing decision.
