The dominant issue was whether a stylus pen used with a digitizer screen is classifiable as an ADP machine unit under heading 8471. Applying Chapter Note 6(C), it was held that an X-Y coordinate input unit must be connectable to the CPU (through the digitizer) and capable of delivering data; the stylus pen satisfied these conditions as it interfaces via the screen and provides coordinate data.

The stylus pen was classified under sub-heading 84716090. - AAR
