When it comes to EMC performance, almost any component can become critical; so your entire Bill of Material plus your assembly drawings become critical. That is why you must insure that your production is compliant. You are not only verifying that the parts make up a compliant device but the way your product is produced is compliant. Any change in components and/or the assembly process needs to be reviewed by someone who is qualified to determine if the change may affect compliance and have the change tested prior if necessary.
In the old days we used to have our products witness tested for EMC by a VDE engineer to get the GS mark. These engineers would generate the test report and include pictures and a list of all the sub assemblies. This is the closest thing to a critical component list I have seen in EMC reports.
Of course, if shielded cables, power cords, or special installation instructions are required to insure compliance then this information should be included in the EMC test report.

Subject: Critical component in EMC report
It is common not to have critical component list in EMC reports issued from 3rd party laboratories. Those information are essential to track if the correct parts to be used in mass production. What is main reason not to have it as a common practice in the field?
Thanks and regards,
Scott
