Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper alloy tube plugs or pipe fittings
Copper plumbing components are Chapter 74; solder wire remains base metal soldering product.
If as parts of soldering torches or kits
Soldering equipment parts use 8311.90; standalone flux-cored wire is the solder itself.

Import Tips & Compliance
• Certify compliance with NSF/ANSI 61 for drinking water contact; required for plumbing classification
• Avoid import with lead-free pipe fittings to prevent set classification issues
• Document diameter and core thickness; thin wires risk reclass to Chapter 83 other articles
