Jeff, all of the power supply modules I have dealt with had EMC Reports.
Those modules went inside products. So I would have required the PSU to
have a vendors EMC report before accepting its use in one of our products.
The suppliers I dealt with used 3 different resistive loads, during their
testing. One minimal load, one mid load and one max load. The resistors
where typically bolted to an aluminum sheet for heat dissipation.
One of the reasons you want them to test is for line conducted levels.
Those levels are usually impacted by load. There is likely nothing you can
do in your product, to correct the power supplies if they failed line
conducted.
Turkey was always difficult for me. I had to on numerous occasions explain
how to interpret the European requirements. I would provide a copy of your
products EMC report, highlighting the power supply was part of the test,
and therefore a valid EMC report for the power supply.

Having a problem sending replacement 1U PSUs into Turkey. Apparently they
(customs) are requiring full EMC certification, which no PSU manufacturer
does. They do LVD, RoHS, but not EMC. These are useless outside of a system
they are intended to be installed into and certified in. PSU manufacturer
DoC explains this. We certify in a full system.
I am under the impression that Turkey is supposed to be following EU CE
rules. We do not have this issue in any other country on the planet. Has
anyone else run into this problem?
