Approvals and Certifications

I m looking for an embedded device that I can hook up to my “not yet” designed pcb, probably the WISMO or WMP series and it shows the following approvals : R&TTE, CE, GCF, FCC, PTCRB, China RTE
I don’t know what are the requirements to have the embedded device built in a PCB and deploy it into the field. ?

Do I need extra certifications ? or approvals, ? for the US and the rest of the world. or do I inherit the existing approvals ?
