U.S. imports of coated rods and cored wire of base metal for soldering, brazing or flame welding (HS 831130) totaled $14.0M in July 2026, traded with 26 countries.
Importers of Coated Rods and Cored Wire of Base Metal for Soldering, Brazing or Flame Welding paid $1.4M in duties in July 2026 — an effective duty rate of 12% on $11.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Coated Rods and Cored Wire of Base Metal for Soldering, Brazing or Flame Welding imports of $14.0M in July 2026 ran 42% above the year-to-date monthly average of $9.8M.
Last updated: July 2026 dataFiller metals designed for lower-temperature joining processes — soldering, brazing, and flame (oxy-fuel) welding — are classified under heading 8311.30, which the US schedule divides into lead-tin solders (8311303000) and all other coated rods and cored wire for these processes (8311306000). Lead-tin solders remain in use in electronics rework and plumbing repair despite RoHS-driven shifts toward lead-free alternatives in new manufacturing. Importers of lead-containing solder should be aware of EPA and state-level restrictions on lead content in plumbing applications, which affect downstream use even if they do not alter customs classification.

Lead-tin solders clear customs under 8311303000 without a mandatory admissibility permit, but downstream use is regulated. The EPA restricts lead-containing solder in potable water plumbing under the Safe Drinking Water Act, and many states have additional restrictions. Importers should ensure their customers are aware of applicable end-use limitations, particularly for plumbing and electronics applications.
Coated rods and cored wire of base metal for brazing are classified under 8311306000 when the filler metal is a base metal alloy (e.g., copper-phosphorus, copper-zinc). Silver brazing alloys with a significant precious metal content may instead be classified under Chapter 71 as articles of precious metal. The silver content threshold and whether the article is considered a precious-metal product are the key classification factors.
