U.S. imports of Self-Propelled Mechanical Shovels & Excavators with 360-Degree Revolving Superstructure (HS 842952) totaled $413.1M in August 2026, imported from 26 countries.
Importers of Self-Propelled Mechanical Shovels & Excavators with 360-Degree Revolving Superstructure paid $64.2M in duties in August 2026, an average duty rate of 15.69% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataFull-slew excavators — the dominant machine type on construction and demolition sites worldwide — are defined by their ability to rotate the upper works a full 360 degrees and are split in the US schedule primarily by undercarriage type (crawler versus non-crawler) and actuation method (hydraulic versus non-hydraulic). New crawler-mounted hydraulic units, the most common configuration, enter under 8429521010, while used and rebuilt full-slew excavators of all types are consolidated under 8429521050. Japan and South Korea together account for the preponderance of US imports, driven by the global manufacturing scale of their major excavator OEMs; Thailand has emerged as a significant production hub for Japanese-brand machines.

The defining criterion is the superstructure's rotation capability. Machines whose upper works can rotate a full 360 degrees — the standard configuration for modern hydraulic excavators — fall under 842952. Machines limited to partial-swing operation, such as backhoes mounted on a fixed frame or draglines without full-circle rotation, are classified under 842959.
Yes. Full-slew hydraulic excavators of Chinese origin are subject to Section 301 tariffs. Given that China is a top-four supplier under this heading, importers should verify the current applicable Section 301 list and any exclusion orders with a licensed customs broker prior to entry.
