8504.40.60 - Suitable for physical incorporation into automatic data processing machines or units thereof of heading 8471

This HTS category, 8504.40.60, specifically encompasses static converters designed for incorporation into automatic data processing (ADP) machines or their constituent units, as defined under heading 8471. This designation is critical, as it isolates power supplies intended for ADP systems from other types of static converters. The key defining characteristic is the intended physical integration within the structure of ADP machinery, rather than being a standalone unit for general use.

This sub-classification differentiates itself from its sibling category, 8504.40.70 "Other," which would cover static converters not meeting the specific ADP machine integration criteria. Therefore, if a static converter is designed to power a personal computer, server, or other ADP equipment, it falls here. If it's a general-purpose power supply for unrelated electronic devices or industrial applications, it would likely be classified under the "Other" sibling category.

The subdivisions within 8504.40.60 further refine classification based on the electrical output capacity of the power supply. This granular breakdown allows for precise identification based on the wattage provided, distinguishing between lower-power units (not exceeding 50 W), mid-range units (exceeding 50 W but not exceeding 150 W), and higher-power units (exceeding 150 W but not exceeding 500 W). An "Other" subcategory exists for any units exceeding 500 W, ensuring comprehensive coverage within the scope of ADP power supplies.
