9612.10.10 - Measuring less than 30 mm in width, permanently put up in plastic or metal cartridges (whether or not containing spools) of a kind used in typewriters, automatic data processing or other machines

This HTS category specifically classifies typewriter or similar ribbons that are permanently put up in plastic or metal cartridges and measure less than 30 mm in width. These cartridges are designed for use in typewriters, automatic data processing machines, or other similar mechanical or electronic devices that require an inked ribbon for imprinting. The defining characteristic is the permanent packaging within a cartridge of a specific width, distinguishing them from other forms of inked ribbons.

This subheading differentiates itself from its sibling category, 9612.10.90, which encompasses all other types of inked ribbons not meeting the specific cartridge and width criteria described here. The focus on permanently housed, narrow ribbons in cartridges ensures that only these specialized items are captured within this classification.

The subcategories within 9612.10.10 further refine the classification based on the material of the ribbon itself. This allows for a more granular tracking of traded goods, differentiating between ribbons made from woven man-made fibers (9612.10.10.10) and those made from other materials (9612.10.10.20). This distinction is critical for statistical purposes and potential trade agreements.
