U.S. imports of parts for clock cases & similar timing device cases (HS 911290) totaled $125K in April 2026, traded with 7 countries.
Last updated: April 2026 dataParts for clock cases and cases for analogous timing devices — classified under a single 10-digit line, 9112900000 — serve the repair, assembly, and OEM manufacturing segments of the horological industry. Mexico leads US import supply for this heading, followed by China and Canada, reflecting cross-border manufacturing integration in North American clock assembly operations. Because these parts are distinct from movement components (classified elsewhere in Chapter 91), correct classification hinges on whether the part is specifically designed for the case structure rather than the timekeeping mechanism itself.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Parts for clock cases (911290) cover components that form or attach to the external housing — such as feet, hinges, bezels, and glass panels — rather than the movement or its subassemblies. Movement parts, springs, and jewels are classified in heading 9114. Misclassification between these headings is a common audit finding, so importers should document the specific function of each part.
Mexico and Canada together represent a significant share of US imports under this heading. Goods originating in Mexico or Canada may qualify for preferential duty treatment under USMCA, provided applicable rules of origin are met and proper certification of origin is maintained. This can meaningfully reduce landed cost compared to sourcing from non-FTA partners.
