SITCSection 7
U.S. imports of self-propelled moving, grading, leveling & excavating machinery (nes) (SITC 72339) totaled $18.5M in April 2026, traded with 14 countries.
Importers of Self-Propelled Moving, Grading, Leveling & Excavating Machinery (NES) paid $1.8M in duties in April 2026 — an effective duty rate of 10% on $17.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Self-Propelled Moving, Grading, Leveling & Excavating Machinery (NES) imports of $18.5M in April 2026 ran 13% below the year-to-date monthly average of $21.3M.
Last updated: April 2026 dataMotor graders, self-propelled elevating scrapers, and other earth-handling machines not captured by more specific SITC headings are grouped here as a residual category for self-propelled earthworks equipment. Motor graders — widely used in road maintenance and mine haul-road construction — are among the most commercially significant equipment types in this heading. As with other NES headings, correct classification requires confirming the machine does not fit a more specific category, and the corresponding HTS subheadings may further distinguish by engine power or operating weight.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Motor graders are self-propelled machines used for grading and leveling but do not fit the more specific SITC headings for scrapers (72331), rollers (72333), or cutters (72335), so they fall under the NES heading 72339. At the HTS level, motor graders have dedicated subheadings, and engine horsepower is often the key variable that determines the correct 10-digit line.
Depending on the country of manufacture, equipment in this heading may be subject to Section 301 tariffs. Importers should verify the country of origin through a thorough supply-chain review, since assembly location alone does not determine origin — substantial transformation of major components is the operative standard under US customs law.
