63/37 Rosin-Core Lead-Tin Solder
A flux-cored 63% tin / 37% lead solder wire ideal for plumbing and electrical repairs, providing smooth flow and strong bonds. Classified under HTS 8311.30.3000 due to its lead-tin composition and flux core for flame soldering. The rosin flux minimizes oxidation during use.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as base metal parts or accessories for soldering
Other base metal parts of soldering equipment are under 8311.90, excluding the solders themselves.
If aluminum-based brazing rod instead of lead-tin
Aluminum brazing rods are classified under Chapter 76 for aluminum products, not base metal solders.
If for other coated rods not specifically lead-tin
Non-lead-tin flame soldering rods use 8311.30.1000, while this subheading is exclusive to lead-tin alloys.

Import Tips & Compliance
• Label packages with alloy percentage and flux type; customs requires proof of flux coring for this subheading
• Include EPA lead hazard warnings and ensure compliance with Proposition 65 for California imports
• Test for purity to prevent reclassification as scrap metal under Chapter 80 if contaminated
