Wondering when CMYK would arise. Gimp is a RGB editor, no CMYK. There is a plugin that can export a CMYK jpeg or psd however your best bet is not Gimp it is Krita. https://krita.org/en/
Really you should start and finish all of a project in CMYK colorspace but you can import an RGB image and convert the colour space to CMYK before exporting as a photoshop psd file. No PDF export in Krita (probably a good thing) and PNG does not support CMYK only RGB. Which makes me suspect that specification.
Most printing companies these days will take a RGB image with a warning that the colours can change. (read the advice here https://www.rgb2cmyk.org/about.html)

Thanks again for your help Rich!
Lots of stuff to digest.
