8473.30.11.80 - Other

This HTS category, 8473.30.11.80, encompasses "Other" printed circuit assemblies (PCAs) specifically designed for use with machines classified under heading 8471. These PCAs are distinct from memory modules, which are covered under the sibling category 8473.30.11.40. While memory modules are dedicated to storing data, the "Other" PCAs within this subcategory include a diverse range of electronic assemblies that perform various functions essential to the operation of machines of heading 8471, such as processors, input/output controllers, or graphics processors.

The key defining characteristic for classification under this heading is that the printed circuit assembly must be suitable for use solely or principally with machines of heading 8471, which pertains to automatic data processing machines and units thereof. This excludes PCAs intended for general electronic devices or other types of machinery. The assemblies classified here are those not specifically enumerated in other subheadings within 8473.30.11, but which still serve a critical role in the functionality of computers and related data processing equipment.

As this is a leaf node, there are no further subdivisions. Therefore, the practical classification criteria rely on a thorough understanding of the specific function and intended use of the printed circuit assembly. Importers and exporters should ensure that the assembly's design and primary application are demonstrably for machines of heading 8471 and that it does not fall under any more specific PCA classification, particularly the dedicated memory modules.
