HS Code for Soldering wire

Soldering wire is classified under HS code 8311.30 because it consists of base metal wire that is cored or coated with flux material for use in soldering or brazing by flame. Chapter 83 covers miscellaneous articles of base metal, and heading 8311 is specifically dedicated to wire, rods, tubes, plates, and electrodes of base metal or of metal carbides, which are coated or cored with flux material. The classification 8311.30 specifically targets products used for soldering, brazing, or welding by flame. The defining characteristic for this code is the presence of a flux core (such as rosin or acid) or a flux coating. This flux is essential for the soldering process as it cleans the metal surfaces and prevents oxidation during heating. Without this flux component, the wire would be classified based on its constituent metal (e.g., tin or lead) in their respective chapters. The inclusion of the flux makes it a specialized article for joining metals, thus placing it under the specific provisions of heading 8311.

Products Included

• Rosin-core solder wire
• Acid-core solder wire for plumbing
• Flux-cored silver solder wire
• Aluminum soldering wire with internal flux
• Lead-free flux-cored soldering wire

Common Misclassification

Soldering wire is frequently misclassified under 8003.00 (Tin bars, rods, and wire). The distinction lies in the flux; 8003.00 is for solid tin wire without any flux core. Another common error is using 8311.10, which is reserved for coated electrodes for electric arc-welding. Since soldering wire is typically used with a soldering iron or flame rather than an electric arc, 8311.30 is the correct designation.

FAQ

What is the HS code for Soldering wire?

The HS code for flux-cored or coated soldering wire of base metal is 8311.30.

Does this code apply to solid wire without flux?

No, solid wire without a flux core or coating is classified by its metal composition, such as 8003.00 for tin or 7408.19 for copper.
