There are a number of things you could conceivably be doing that would complicate your compliance situation beyond simply using the module's certification, getting test data from a certified lab for unintentional radiation for the Supplier's Declaration of Conformance procedure, appropriate labeling, and so on. (You're right that's a reasonable assumption about your situation but it may not always be true). They include but are not limited to, say, using more than one pre-certified transmitter in your device.
