U.S. imports of non-automatic electric resistance welding machines (HS 851529) totaled $1.0M in April 2026, traded with 19 countries.
Importers of Non-Automatic Electric Resistance Welding Machines paid $93K in duties in April 2026 — an effective duty rate of 12% on $803K in dutiable value, based on actual customs collections rather than the published tariff schedule. Non-Automatic Electric Resistance Welding Machines imports of $1.0M in April 2026 ran 62% below the year-to-date monthly average of $2.7M.
Last updated: April 2026 dataManual and non-automatic electric resistance welding machines — where the operator positions the workpiece and initiates each weld cycle without automated sequencing — are classified here under a single US tariff line (8515290000). Canada leads supply under this heading, reflecting cross-border trade in industrial equipment within integrated North American manufacturing, with Germany and the United Kingdom also among the top sources. These machines are widely used in job shops, maintenance operations, and lower-volume fabrication where the capital investment in full automation is not justified. The non-automatic designation is the defining classification criterion separating this heading from the fully or partly automatic machines of 851521.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A programmable weld timer alone does not make a machine 'automatic' for classification purposes. Automation in this context refers to the mechanical or electronic sequencing of the welding cycle including workpiece handling or electrode movement, not merely electronic control of weld parameters. A machine with a digital timer but manual part loading and actuation would generally remain classified under 851529 as non-automatic.
Canadian-origin resistance welding machines may qualify for preferential tariff treatment under USMCA, provided the goods meet the applicable rules of origin — typically a tariff classification change requirement. Importers should obtain a USMCA certification of origin from the Canadian supplier and verify that the machine's components and manufacturing process satisfy the relevant origin criteria before claiming the preference.
