U.S. imports of Continuous-Action Elevators & Conveyors for Underground Use (Non-Pneumatic) (SITC 74472) totaled $4.5M in August 2026, imported from 11 countries.
Importers of Continuous-Action Elevators & Conveyors for Underground Use (Non-Pneumatic) paid $431K in duties in August 2026, an average duty rate of 9.57% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Continuous-Action Elevators & Conveyors for Underground Use (Non-Pneumatic) imports of $4.5M in August 2026 ran 76% above the year-to-date monthly average of $2.5M.
Last updated: August 2026 dataDesigned specifically for mining, tunneling, and underground construction environments, these non-pneumatic continuous-action conveyors must withstand confined spaces, explosive atmospheres, and heavy abrasive loads — requirements that set them apart from surface-duty equipment. Coal mining and hard-rock mineral extraction are the primary end-use sectors, where armored face conveyors and chain-and-flight systems dominate. SITC 74472 captures only non-pneumatic designs engineered for underground service, so surface-duty belt or bucket conveyors of otherwise similar construction fall into separate SITC lines.

Customs authorities generally look for design features specific to subterranean operation: flame-retardant belting or casing, explosion-proof electrical components, low-profile frames sized for mine roadways, and reinforced construction for abrasive ore loads. Generic surface conveyors that happen to be installed underground do not automatically qualify under this classification.
Certain steel components incorporated into underground conveyor systems may be subject to Section 232 tariffs on steel and aluminum. The complete machine's classification and country of origin determine whether additional Section 301 or antidumping measures apply; a customs broker should review both the equipment and its major subcomponents.
