U.S. imports of Laser, Ultrasonic & Other Specialty Brazing/Welding Machines; Hot Metal Spraying Equipment (HS 851580) totaled $70.4M in August 2026, imported from 40 countries.
Importers of Laser, Ultrasonic & Other Specialty Brazing/Welding Machines; Hot Metal Spraying Equipment paid $7.0M in duties in August 2026, an average duty rate of 9.99% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Laser, Ultrasonic & Other Specialty Brazing/Welding Machines; Hot Metal Spraying Equipment imports of $70.4M in August 2026 ran 90% above the year-to-date monthly average of $37.1M.
Last updated: August 2026 dataPrecision joining technologies — including laser beam welders, ultrasonic bonding machines, and electric hot-spraying systems for metals and sintered metal carbides — are the commercial focus of this heading, serving aerospace, automotive, and advanced electronics manufacturers. Germany and Japan dominate US supply, reflecting the high engineering content and proprietary process technology embedded in these systems. The US schedule separates ultrasonic welding machines (8515800040) from electric hot-spraying metal machines (8515800080), a distinction that matters for Section 301 exposure on Chinese-origin equipment. Importers should verify whether laser or electron-beam welding units meet the 'electric' qualifier required for classification here rather than under optical or other machinery headings.

Ultrasonic welders join materials through high-frequency mechanical vibration and are classified at 8515800040, while electric hot-spraying machines — which melt and propel metal or sintered carbide particles onto a substrate — fall under 8515800080. The two lines may carry different duty rates, so correct technical documentation from the manufacturer is essential before filing entry.
Laser, ultrasonic, and hot-spraying systems require advanced process engineering and tight manufacturing tolerances, areas where German and Japanese capital-equipment makers have long-established expertise and installed customer bases in US aerospace and automotive plants. This concentration creates lead-time and sourcing risk for buyers when demand spikes or export controls shift.
