What code are you asking for?
Do you mean the ink mixture? Why do you need it? It depends on the color output profile. Use that color and go to the ink manager and tell it to convert this color into process color. InDesign will change this color to a process color mixture depending on your color mangegement setting.
It will work in placed graphics and images too, but don't use EPS and Distiller, as postscript does not support color management, so it will fail, use only AI, PDF or PSD files.
I can't find it on my swatches library in INDESIGN... I think that 2171C is a new color and is not avaible on my library...
