9606.30.80.00 - Other

This category, HTS 9606.30.80.00, encompasses "Other" button molds, other parts of buttons not otherwise specified, and button blanks. It serves as a residual category for components used in the manufacture or completion of buttons that do not fit into more specific subheadings. Examples include unfinished button blanks made from a variety of materials, pre-formed molds used to shape button components, and any other distinct parts of buttons that are not themselves complete buttons.

It is crucial to distinguish this "Other" classification from its sibling, HTS 9606.30.40.00, which specifically covers "Button blanks of casein." While both deal with button blanks and parts, this current category is for those made from any material other than casein, or for button molds and other unspecified button parts. The material of the button blank or the specific function of the part are key differentiating factors.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the primary focus for classification within HTS 9606.30.80.00 is to ensure that the article in question is indeed a component or unfinished item related to buttons, and that it does not meet the specific criteria for any preceding subheading within 9606.30.
