U.S. imports of gas-operated machinery & apparatus for soldering, brazing & welding (nes) (SITC 73742) totaled $1.1M in April 2026, traded with 13 countries.
Importers of Gas-Operated Machinery & Apparatus for Soldering, Brazing & Welding (NES) paid $117K in duties in April 2026 — an effective duty rate of 11% on $1.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Gas-Operated Machinery & Apparatus for Soldering, Brazing & Welding (NES) imports of $1.1M in April 2026 ran 46% above the year-to-date monthly average of $770K.
Last updated: April 2026 dataGas-fueled soldering, brazing, and welding machinery not captured by more specific SITC headings — such as automated oxy-fuel cutting tables, gas-fired brazing furnaces, and specialty flame-processing units — falls under SITC 73742. These systems are widely used in metal fabrication, automotive parts production, and HVAC equipment manufacturing where gas-flame processes remain cost-competitive with electric alternatives. The NES scope means importers must rule out classification under more specific gas-welding or cutting headings before using this code. Origin-based tariff exposure, including potential Section 301 applicability, should be evaluated at the HTS subheading level.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Start by checking whether the equipment fits a named, more specific SITC heading for gas welding or cutting machines. If no specific heading applies — for example, the machine performs a combination of gas-flame brazing and surface heating without a dedicated code — SITC 73742 is the appropriate residual classification. A licensed customs broker can assist with the HTS-level determination.
A manufacturer's specification sheet identifying the fuel gas type, process description (brazing, soldering, or welding), degree of automation, and intended industry application is the most useful document. If the machine performs multiple functions, a functional breakdown showing the primary use supports the classification decision and can be provided to CBP if questioned.
