Thermal-transfer ribbons are functionally similar to inked ribbons and have generally been classified in this heading, but the classification can be contested depending on the ribbon's construction and the printer type. Importers of high-volume thermal-transfer ribbon should verify current CBP guidance or obtain a binding ruling, as some lines have been argued under printer-parts headings.

Yes — the heading explicitly includes ribbons and pads 'whether or not inked,' so uninked ribbon stock on spools and dry pads (with or without boxes) are classified here as long as they are prepared or designed for use as inking media. Raw textile ribbon not configured for inking would not qualify.
