9110.19.00.00 - Rough movements

This HTS category, 9110.19.00.00, specifically covers rough watch movements. These are essentially the fundamental components of a watch movement that have undergone initial manufacturing but have not yet been assembled or fully machined to a state where they can function as a complete mechanism. Unlike more finished stages, rough movements are characterized by their raw or partially processed nature, requiring significant further work before they can be incorporated into a timepiece.

In contrast to its sibling categories, this classification excludes complete watch movement sets (unassembled or partly assembled) under 9110.11.00.00, which are essentially kits of parts ready for assembly. It also excludes incomplete but assembled movements under 9110.12.00.00, which represent partially functioning mechanisms. The key differentiator for 9110.19.00.00 lies in the unfinished, un-machined, or largely unprocessed state of the components before the final stages of movement construction.

As a leaf node in the HTS structure, 9110.19.00.00 does not have further subcategories. Therefore, the classification relies on a precise understanding of what constitutes a "rough" watch movement. This typically includes parts like blanks for bridges, plates, or mainspring barrels that have been stamped or roughly cut but have not yet had holes drilled, surfaces finished, or escapement components shaped. The emphasis is on the initial stage of raw material transformation into fundamental movement parts.
