Product classification
HS code for Watch cases: 9111.90
Watch cases and parts thereof.
Classification of watch cases under HS 9111.90
Watch cases and their parts are classified under HS code 9111.90. This classification is part of Chapter 91, which encompasses clocks, watches, and their parts. Heading 9111 is dedicated specifically to watch cases, while the subheading 9111.90 addresses the individual components that make up a case. The classification logic is based on the fact that these items are identifiable parts of a watch case but do not constitute a complete case assembly. Under the General Rules of Interpretation, parts of articles are classified with those articles if they are suitable for use solely or principally with those articles. Since these components are precision-engineered for watch assembly, they fall under this specific parts category. This code applies regardless of the material of the part, whether it be base metal, stainless steel, or plastic, provided it is not a precious metal (which might affect the heading level but usually stays within 9111).

Codes often confused with 9111.90
Common mistake. Watch case parts are often confused with complete watch cases, which are classified under 9111.10 (precious metal), 9111.20 (base metal), or 9111.80 (other materials). Another common error is classifying watch crystals under this code; however, watch glasses/crystals are typically classified under 7015.10. General-purpose parts like screws or springs are classified in their respective material chapters (e.g., Chapter 73 for steel screws) rather than 9111.90.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
