Analysis
HTS 9105.99.10 covers standard marine chronometers having spring-detent escapements under heading 9105 (other clocks).
The general rate is 17¢ each + 2.5% + 1¢/jewel, a specific or compound duty rather than a simple percentage, so the effective burden depends on the unit value of the goods: cheap goods pay proportionally more than expensive ones. Importers usually convert it to an ad valorem equivalent to compare it with other lines.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 12 others can enter duty-free instead of paying 17¢ each + 2.5% + 1¢/jewel. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.
Census statistics map these goods to NAICS 334519 (Other Measuring and Controlling Device Manufacturing), an industry of 913 US establishments employing 34,818 people, the industry a domestic producer of these goods reports under.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of 17¢ each + 2.5% + 1¢/jewel.
