8443.99.50.11 - Ink cartridges

This subheading encompasses ink cartridges specifically designed for use with printers classified under subheading 8443.31. These cartridges are self-contained units that deliver ink to the printing mechanism, featuring components such as ink reservoirs, print heads (in some integrated designs), and connections for interfacing with the printer. The classification here is determined by the specific intended application of the cartridge within a particular type of printing machinery.

This category is distinguished from its sibling, 8443.99.50.15, which covers "Other" ink cartridges. While both relate to ink cartridges, this subheading is narrowly defined for those compatible with the printers of 8443.31. Subheading 8443.31 typically refers to certain types of multi-function printers, and therefore, cartridges classified here must be exclusively for such machines.

As this is a leaf node within the HTS, there are no further subcategories. The classification of an ink cartridge under 8443.99.50.11 hinges on its direct compatibility and intended use with printers falling under subheading 8443.31. Importers should ensure their documentation clearly supports this intended use.
