HTS heading 9106 is a broad product category for apparatus that measures, records, or displays intervals of time and that contains either a clock or watch movement or a synchronous motor. It can include time registers, time-recorders, and similar equipment—not ordinary clocks simply because they show the time. The key question is what the apparatus does and what mechanism it uses.
To reach the correct 8-digit HTSUS code, start with the product’s principal function and construction, then review the more specific subheadings under 9106. The 8-digit distinctions may depend on the apparatus type, how it records or indicates time, and its operating mechanism or other listed characteristics. Read the full wording of each candidate provision, along with the legal notes and applicable classification rules; do not choose based only on a catalog name or a similar-looking product.
What to check
- Check the product’s actual function: does it measure, record, or indicate an interval of time, and is that function central to the imported article?
- Confirm whether the item contains a clock or watch movement or a synchronous motor; document the mechanism in technical specifications.
- Compare the complete product description with every applicable 8-digit subheading under 9106, including distinctions based on type, construction, or operation.
- Do not assume that material alone determines the code; use material only when the tariff text makes it a relevant distinction.
- Keep product literature, photographs, wiring or mechanism details, and prior binding rulings or broker advice available to support the classification.

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.
