8504.90.96.50 - Of static converters

This HTS category, 8504.90.96.50, specifically covers miscellaneous "other parts" of static converters. Static converters, as defined in the parent headings, are devices that change electrical energy from one form to another without the use of moving parts. This includes, but is not limited to, rectifiers, inverters, and AC-to-DC or DC-to-AC converters. The parts classified here are those essential components of static converters that are not explicitly covered by more specific subheadings, such as those designated for transformer parts.

The distinction between this category and its sibling, 8504.90.96.90 ("Other"), is important. While both fall under "Other parts" of static converters, this specific subheading is for those parts that do not fit into the more narrowly defined sibling categories. For example, if a part is primarily a component of a transformer, it would likely be classified under 8504.90.80. However, parts like specialized circuit boards, heat sinks, housings, connectors, or even discrete electronic components that are integral to the operation of a static converter, but not specific to transformers or other defined categories, would be directed here.

As this is a leaf node within the HTS structure, there are no further subdivisions. Therefore, classification into 8504.90.96.50 relies heavily on the process of elimination. When a part is identified as being for a static converter and it does not meet the criteria for any more specific subheading under 8504.90, it should be considered for classification under this residual category. The classification should be based on the part's function within the static converter and its physical characteristics.
