ER70KS Flux-Cored Arc Welding Wire
ER70KS is a seamless copper-coated flux-cored wire made from mild steel, designed for high-strength electric arc welding in structural fabrication. Classified under HTS 8311.20.00.00 due to its base metal core filled with flux for arc stability and slag formation during welding.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If flux-coated solid rod instead of cored
Flux-coated products are 8311.10; cored wire with internal flux is distinctly 8311.20.
If for bulk welded tubes, not welding consumables
Finished welded pipes from base metal are Chapter 73; this is raw cored wire for welding process.
If components like wire guides for feeders
Base metal parts of welding apparatus are 8311.90, not the flux-cored wire electrodes.

Import Tips & Compliance
• Include AWS A5.20 certification to confirm flux-cored status and avoid reclassification
• Ensure spools are labeled with wire diameter (e.g
• 0.035") and position (all-position) for accurate reporting
• Test for copper coating integrity, as excessive coating may trigger scrutiny under coating headings
