HTS heading 8410 is a broad product category for hydraulic turbines, water wheels, and regulators used with them, along with their parts. These products convert the energy of moving or falling water into mechanical power, often for generating electricity or driving machinery. The heading groups complete equipment and qualifying parts, but it does not mean every water-related machine belongs here.
To reach the correct 8-digit HTSUS code, first confirm that the product belongs in heading 8410, then follow the subheadings and statistical provisions under that heading. The split may depend on the equipment’s type, design, function, capacity, or whether it is a complete machine or a part; it is not necessarily based only on material. Read the full legal description, section and chapter notes, and any applicable exclusions before selecting the code. A customs broker or classification specialist may be needed for complex equipment or parts.
What to check
- Confirm whether the item is a hydraulic turbine, water wheel, regulator for such equipment, or a qualifying part—not simply any pump, generator, valve, or water-powered product.
- Identify the product’s principal function, construction, operating method, and technical specifications; keep drawings, manuals, catalogs, and photographs available.
- Check whether the item is complete equipment, an accessory, or a part designed principally for use with machinery covered by heading 8410.
- Compare every 8-digit option and read its full wording, including units, capacity or design distinctions, and any subordinate notes.
- Verify the current HTSUS text and seek broker or specialist review when the product is multifunctional, imported as a set, or the part could fit more than one heading.
HTS heading 8410 summary
Hydraulic turbines is a 4-digit product category containing 4 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
