U.S. imports of parts & regulators for hydraulic turbines and water wheels (SITC 71819) totaled $6.8M in July 2026, traded with 27 countries.

Importers of Parts & Regulators for Hydraulic Turbines and Water Wheels paid $1.9M in duties in July 2026 — an effective duty rate of 29% on $6.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.

Last updated: July 2026 data

Governors, 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.

Frequently Asked Questions

Are turbine speed governors classified under this parts heading or separately as control instruments?

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.

What documentation is typically needed when importing replacement runner blades for a Francis turbine?

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.
