8473.30.11 - Printed circuit assemblies

This HTS category, 8473.30.11, specifically covers printed circuit assemblies (PCAs) that are designed as parts or accessories for machines classified under heading 8471. These assemblies are populated with electronic components and are essential for the functioning of computing machines, data processing machines, and related equipment. The primary characteristic is the presence of a circuit board with mounted components, forming a functional unit.

It is important to distinguish this category from its sibling, 8473.30.20.00, which covers "parts and accessories, including face plates and lock latches, of printed circuit assemblies." While 8473.30.11 is the assembly itself, 8473.30.20.00 refers to components *of* those assemblies or items that attach to them, such as protective coverings or securing mechanisms, rather than the functional electronic board.

Further subdivision within 8473.30.11 is based on the specific type of printed circuit assembly. The subcategory 8473.30.11.40 is dedicated to memory modules, such as RAM or ROM, designed for use with machines of heading 8471. The remaining PCAs that do not fall into the memory module classification are covered under the broader subcategory 8473.30.11.80, "Other." This distinction allows for more precise tariff treatment based on the specific function and design of the PCA.
