HTS heading 9110 is a broad product category for watch and clock movements that are not necessarily finished products. It covers complete movements that are unassembled or partly assembled (called movement sets), incomplete movements that are assembled, and rough movements. A movement is the mechanism that drives the hands or other time display; the category generally does not describe a complete watch or clock with its case and other components.
To narrow heading 9110 to an 8-digit HTSUS code, first identify the item’s condition and type: for example, whether it is a movement set, an assembled but incomplete movement, or a rough movement, and whether it is intended for a watch or a clock. Then review the applicable subheadings and statistical suffixes, which may distinguish characteristics such as construction, material, or other technical features. Use the product’s actual specifications and the HTSUS descriptions—not its marketing name—to select the code. When the distinctions are unclear, obtain a customs broker’s or classification specialist’s review.
What to check
- Confirm whether the shipment is a watch movement, a clock movement, or a set of movement components.
- Document whether the movement is complete but unassembled or partly assembled, assembled but incomplete, or rough.
- Check the movement’s technical specifications, including construction, materials, power source, dimensions, and intended use, against the relevant subheading descriptions.
- Compare the complete 8-digit wording and any applicable statistical suffixes in the current HTSUS; do not stop at heading 9110.
- Keep product drawings, supplier specifications, photographs, and assembly information to support the classification if Customs asks for evidence.

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.
