8471.60 - Input or output units, whether or not containing storage units in the same housing:

This HTS category, 8471.60, encompasses a broad range of essential components for automatic data processing (ADP) machines: input and output units. These units are designed to either receive data into the ADP system (input) or present processed data from the system (output). Crucially, this classification applies even if these input or output units incorporate storage functionalities within the same housing, distinguishing them from standalone storage units.

Unlike sibling categories such as processing units (8471.50), which focus on the central processing capabilities, or storage units (8471.70), this category is strictly concerned with the interfaces through which data enters or leaves the ADP system. For instance, keyboards, mice, and scanners fall under input units, while monitors, printers, and speakers are typical output units.

Within this heading, the subcategories further refine the classification. Subheading 8471.60.10 specifically addresses combined input/output units, which perform both functions within a single device. The remaining "Other" subcategory is for units that exclusively function as either input or output devices, requiring further subdivision based on the specific nature of the unit.
