8471.70 - Storage units:

HTS code 8471.70 encompasses various types of storage units designed to be integrated with or function as part of automatic data processing (ADP) machines. This category is specifically for the hardware responsible for storing digital data, including both primary and secondary storage devices. The core function of these units is to retain information for processing by ADP systems, distinguishing them from the processing units themselves or the input/output peripherals.

This classification is distinct from its sibling categories. For instance, it does not include complete portable ADP machines (8471.30), nor does it cover standalone processing units which may incidentally contain storage components (8471.50). Furthermore, input or output units, even if they incorporate storage, are classified under 8471.60. The focus of 8471.70 is solely on the storage mechanism as a distinct component or unit.

The subcategories within 8471.70 further refine the classification of storage units. The primary subdivisions typically differentiate between magnetic disk drive units and other types of storage units. This allows for specific identification of technologies like hard disk drives, solid-state drives (SSDs), optical drives, or other non-volatile memory devices based on their fundamental data storage medium and operational principles.
