Ioan, See IPC-9261. It's not real clear which category of opportunity polarity falls into, but I would include it as a placement defect. Placement opportunities are separate from termination opportunities, and there's one placement opportunity per component whether or not the component has a polarity.

And I mean beyond diodes, tantalum caps and ICs, for instance connectors or DPAKs. Hypothetically one can mount a DPAK at 90, 180 or 270 degrees. It is obvious, easy to see if this part, or an RJ connector is mounted in a different position than required, but are they considered polarized parts when doing the opportunities count?
