8471.80.40.00 - Units suitable for physical incorporation into automatic data processing machines

This HTS classification, 8471.80.40.00, specifically covers units designed and intended for physical integration within automatic data processing (ADP) machines. These are components that, while not complete ADP machines themselves, are manufactured to be an integral part of a larger computing system, contributing directly to its operational functionality. Examples include specialized input/output modules, internal data storage controllers, or internal networking interfaces that are not standalone devices but are meant to be installed within the chassis of an ADP machine.

This category is distinguished from its sibling, 8471.80.90.00, which is designated for "Other" units of ADP machines. While 8471.80.40.00 is reserved for units specifically suited for physical incorporation, 8471.80.90.00 would likely encompass a broader range of auxiliary or complementary units that may not necessarily be designed for direct physical integration, or perhaps those that have some standalone functionality but are still considered units of ADP machines. The key differentiator lies in the explicit design intent for physical integration into the main body of an ADP machine.

As this node is a leaf node within the HTS, there are no further subcategories. Therefore, classification under 8471.80.40.00 hinges entirely on the unit's physical suitability and intended purpose for integration into automatic data processing machines. Importers and exporters should ensure that the unit's design and documentation clearly support its role as a component intended for direct installation and operation within an ADP machine.
