HTS heading 9109 covers complete and assembled clock movements—the operating mechanisms that drive a clock’s hands, display, or other timekeeping function. The heading is a broad product category, not usually the final classification used for entry. It can include movements supplied as finished units, whether or not they are installed in a clock case.
To reach the correct 8-digit HTSUS code, start with the movement’s characteristics and read the subheadings under 9109. The breakdown commonly distinguishes features such as the movement’s type or operating method and the materials or construction used. Confirm the exact wording, including any notes and statistical suffixes, because similar-looking movements may fall under different codes. The complete product—not just its marketing name—must match the chosen description.
What to check
- Identify whether the item is a complete, assembled clock movement rather than a part, component, or complete clock.
- Record the movement’s operating method, such as mechanical, electronic, or another applicable type, and verify how the HTSUS describes it.
- Check the movement’s construction and material characteristics where the subheadings use those distinctions.
- Read every subheading, legal note, and statistical suffix under heading 9109; do not choose an 8-digit code from the heading title alone.
- Compare the product specification sheet, photographs, and physical sample with the tariff wording, and ask a customs broker or request a binding ruling if the classification remains uncertain.

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.
