Inspection Required checked when it should not be

I have a part where its part class is NOT checked as inspection required and the supplier is NOT checked as inspection required. The revision is under Skip Lot control but the skip count is under the defined number (7 out of 18).

When I create a test PO for this part, the PO line defaults to inspection required and when I receive it, it does go into Inspection Processing.

My expectation is the inspection would not be required.
What am I missing?

The only other place out-of-the-box that would set the Receiving Inspection Required flag is on the Supplier record. Beyond that, check for BPMs and customizations…

Additional information.
We recently rolled out a new Site.
The part number in question should be processed within the new site.
If I create a PO for this part number in the original site (MfgSys) the Inspection Required box is enabled and unchecked by default. If I create a PO in the new site (where it should be processed) the Inspection Required box is disabled and checked by default.

Odd…
