It is possible to change the ETIM class for individual items if the ETIM class should be different from the one assigned to the module.
Procedure
Find and export the relevant items:

Open the exported Excel file.
Enter the ETIM class in Column O (ETIM class).
You can search for ETIM classes or item groups in NOBB Supplier here: Product Groups

Important:
If you upload an Excel file with an empty value in the ETIM class column, the ETIM class value will be removed from the item. The item will then inherit the ETIM class set on the module.
