HS Code 8311.90 – Wires, rods, tubes, plates, electrodes of base metal or metal carbides; of a kind used for soldering, brazing, welding; wires and rods for metal spraying; n.e.c. in item no. 8311

HS code 8311.90 is the 6-digit subheading for wires, rods, tubes, plates, electrodes of base metal or metal carbides, of a kind used for soldering, brazing, welding, wires and rods for metal spraying, n.e.c. in item no. 8311. It is used for TIG welding rods (uncoated, specialized alloys), plasma welding electrodes, metal spraying wires (e.g., zinc, aluminum, nickel alloys), specialized brazing foils and welding tubes.

What HS 8311.90 covers

This HS code serves as a residual category for various wires, rods, tubes, plates, and electrodes of base metal or metal carbides used for soldering, brazing, or welding, as well as wires and rods for metal spraying, not specifically covered by other subheadings within 8311. This 'basket' category captures specialized or less common forms of consumables essential for niche applications in manufacturing, repair, and surface engineering. Importers often include specialized welding and thermal spray service providers, aerospace manufacturers, and companies involved in advanced material processing. Exporters are typically manufacturers producing a wide range of welding and surfacing consumables, including those for plasma welding, TIG welding (specific types), and thermal spray processes. The trade in these goods is characterized by high-value, specialized products catering to specific industrial demands, often requiring precise material specifications and certifications for critical applications.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
