Any Wireless Certifications for radio boards?

Do any of the Seeedstudio wireless modules have wireless certifications already, like FCC, CE mark, IC? I’m assuming not because the cost of certification is high and these boards are firstmost for DIY projects, but we’re always looking for a quick way to make commercial devices for clients. It looks like the Grove Serial Bluetooth module might use an off-the-shelf pre-certified module, but most of the other wireless boards look like original products. Right now, I’m currently looking for NFC/RFID and GPRS cellphone connections.
