8473.50 - Parts and accessories equally suitable for use with machines of two or more of the headings 8470 to 8472:

Heading 8473.50 encompasses parts and accessories that are equally suitable for use with machines falling under two or more of the headings 8470 (calculating machines, accounting machines, cash registers, postage-franking machines, ticket-issuing machines and similar machines, incorporating a calculating device) and 8472 (other office machines, such as typewriters, addressing machines, cheque-writing machines, automatic banknote dispensers). This broad scope means that an item classified here is not exclusively designed for a single type of machine within that range but possesses a dual or multi-purpose application.

Distinguishing this heading from its siblings is crucial for accurate classification. Unlike parts specifically for machines of heading 8470 (8473.10), 8471 (automatic data processing machines, 8473.30), or 8472 (8473.40), goods under 8473.50 serve more than one of these categories. For instance, a power supply unit or a generic interface card designed to be compatible with both a sophisticated electronic calculator (8470) and a specialized addressing machine (8472) would likely fall under 8473.50.

Within 8473.50, further subdivisions provide more specific classification. The subcategory 8473.50.30.00 is dedicated to printed circuit assemblies, which are essential components for many modern machines. Complementary parts and accessories for these assemblies, such as face plates and lock latches, are captured under 8473.50.60.00. The residual category, 8473.50.90.00, accounts for all other parts and accessories that meet the primary criteria of 8473.50 but are not specifically enumerated in the preceding subcategories.
