8473.30.11.40 - Memory modules suitable for use solely or principally with machines of heading 8471

This HTS category, 8473.30.11.40, specifically encompasses memory modules designed for integration into computing machines classified under heading 8471. These memory modules are the essential components that store and retrieve data for computers, including random-access memory (RAM) and similar storage devices. The key criterion for classification here is their intended primary use with machines of heading 8471, such as personal computers, servers, and other digital processing machines.

Distinguishing this category from its sibling, 8473.30.11.80 "Other," is crucial. While 8473.30.11.80 would cover other printed circuit assemblies for machines of heading 8471 that are *not* memory modules (e.g., motherboards, graphics cards, network interface cards), this category is exclusively for the memory storage components themselves. The functionality and primary purpose are the differentiating factors: data storage versus processing, input/output, or connectivity.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the focus for classification within 8473.30.11.40 is on confirming that the item is indeed a memory module and that it is intended for use with machines of heading 8471. This may involve reviewing technical specifications, product literature, or even an examination of the module itself to verify its function as a data storage device for computing equipment.
