U.S. imports of Parts & Regulators for Hydraulic Turbines and Water Wheels (SITC 71819) totaled $6.0M in August 2026, imported from 28 countries.
Importers of Parts & Regulators for Hydraulic Turbines and Water Wheels paid $1.4M in duties in August 2026, an average duty rate of 23.88% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataGovernors, speed regulators, runner blades, guide vanes, draft tubes, and other dedicated components for hydraulic turbines and water wheels are grouped here, including the control systems that maintain turbine speed under varying load. Regulators are explicitly named in the heading description, reflecting their commercial importance in grid-connected hydropower where frequency stability depends on precise turbine governing. Replacement parts for aging hydropower infrastructure represent a steady import stream distinct from new-unit procurement.

The SITC heading explicitly includes regulators (governors) as parts of hydraulic turbines and water wheels, so purpose-built hydraulic turbine governors are properly classified here rather than under instrument or control-equipment headings. The key is that the governor must be designed for use with hydraulic turbines; general-purpose industrial governors may classify differently.
Importers should provide the OEM part number, a technical drawing or datasheet confirming the blade is designed for hydraulic turbine use, and the turbine model it serves. If the blades are custom-cast to a specific runner geometry, a mill certificate or material specification may also be requested to confirm composition and support valuation.
