SITCSection 7
U.S. imports of nonelectric metalworking machinery & apparatus (nes) (SITC 73743) totaled $2.2M in April 2026, traded with 18 countries.
Importers of Nonelectric Metalworking Machinery & Apparatus (NES) paid $315K in duties in April 2026 — an effective duty rate of 14% on $2.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Nonelectric Metalworking Machinery & Apparatus (NES) imports of $2.2M in April 2026 ran 15% above the year-to-date monthly average of $1.9M.
Last updated: April 2026 dataHydraulic, pneumatic, and mechanically driven metalworking machines that do not operate on electrical energy and are not captured by more specific SITC headings are grouped under SITC 73743. Typical examples include pneumatic riveting machines, hydraulic press-fit tools, and mechanical metal-forming fixtures used in aerospace, construction equipment, and general fabrication. Because this is a residual NES category, classification requires a two-step analysis: confirming the machine is nonelectric and confirming no more specific SITC code applies. Section 301 tariff exposure may be relevant for equipment sourced from certain origins.

Generally, a machine is classified by its essential character or primary operating principle. If the machine's core metalworking function is driven pneumatically or hydraulically and the electrical components are merely ancillary (e.g., a control panel), it may still qualify as nonelectric. However, if the electric motor is the primary driver of the metalworking action, an electric heading would be more appropriate. CBP guidance or a binding ruling can resolve ambiguous cases.
Aerospace assembly (pneumatic riveting and fastening tools), heavy equipment manufacturing (hydraulic press-fit and forming fixtures), and shipbuilding (mechanical metal-working rigs) are among the primary end-use sectors. These industries favor nonelectric systems in environments where electrical spark risk is a safety concern or where compressed-air infrastructure is already in place.
