U.S. exports of Welding Tubes, Plates, Wire and Rods with Flux Material or of Agglomerated Base Metal Powder (HS 831190) totaled $7.4M in August 2026.
Importers of Welding Tubes, Plates, Wire and Rods with Flux Material or of Agglomerated Base Metal Powder paid $210K in duties in August 2026, an average duty rate of 4.49% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Welding Tubes, Plates, Wire and Rods with Flux Material or of Agglomerated Base Metal Powder imports of $4.7M in August 2026 ran 27% above the year-to-date monthly average of $3.7M.
Last updated: August 2026 dataThe residual welding consumables heading — 8311.90 — captures flux-bearing tubes, plates, and strips of base metal or metal carbides used in hardfacing and overlay welding, as well as wire and rods made from agglomerated (sintered or pressed) base metal powder, all classified under 8311900000. These products serve specialized wear-protection, tooling, and hard-surfacing applications in mining, oil and gas, and heavy equipment industries. The agglomerated powder construction distinguishes these rods from drawn wire and from cast or wrought filler metals, and importers should document the manufacturing method to support classification under this residual line rather than a more specific wire or rod heading.

Agglomerated powder wire or rod is produced by compacting or sintering metal powder into a rod or wire form, rather than by drawing or casting. This manufacturing route is common for tungsten carbide hardfacing rods and specialty alloy rods used in wear-resistant overlay applications. The agglomerated structure — as opposed to a wrought or drawn microstructure — is the defining characteristic for classification under 8311900000.
A tubular steel product filled with flux or alloying powder specifically for welding or hardfacing would fall under heading 8311.90 (8311900000) as a tube of base metal with flux material for welding. It should not be classified as a structural tube (Chapter 73) or as cored wire for arc welding (8311.20) unless it meets the specific product definitions of those headings. Product data sheets confirming the flux-fill composition and intended welding application are essential supporting documentation.
