Import Tips
• 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
