The seller will have to provide the FCC certification information before being able to list the item on amazon
Funny thing is, the Baofengs do have an FCC certification number for Part 90 (commercial use). They are not Part 95 certified, so they are not legal to operate on the FMRS / GMRS. So the Baofengs will not disappear off amazon due to this.
From the amazon link:
in order to create new listings or update existing listings of radio frequency devices you will need to fill in the FCC Radio Frequency Emission Compliance attribute. In the attribute, you must do one of the following:
Provide evidence of Federal Communications Commission (FCC) authorization – either an FCC certification number or contact information for the Responsible Party, as defined by the FCC.
or certify that the product is exempt from FCC requirements.
