At least with axial electros the polarity is self evident due to the rubber seal. But radial ones it relies on the plastic cover being put on and labelled correctly.

Check the physical size of the caps against others, if its a mislabeled 16V one it should be physically smaller than a 63V one of the same capacity.
Some interesting insights there, Hugo. That helicopter wing scam is jaw-dropping and criminal! It's a more sinister version of the old saying, 'Where there's muck, there's brass.'
