I called our Ohio Congressman shortly after the regs went into action. Fortunately, I spoke with a representative in his office who had a direct connect with a Tobacco Rep with the FDA. Thus, e-mails were sent back and forth between the three of us, as I was asking some questions the Rep was getting extremely frustrated with because he didn't know the answers to the questions either! He asked me several times where I was getting the questions I was asking, and I explained they are questions any vape shop owner would be asking. Additionally, they are posted all over vape boards, etc. Needless to say, both of the people I was communicating with were overwhelmed because they didn't know much about the vaping industry when these rules went into affect.
With that said, I have been selling the coils individually. The reason being, I was told since there weren't many members of the FDA who understand the regs themselves, they wouldn't be enforcing anything they didn't know for sure, and the vaping industry is much more complicated and certainly more intricate than they knew. We both agreed to this upon my first question being about the discussions had/we have with our customers about battery safety and battery wraps... which has not been answered to date. Moreover, with the coils being individually wrapped, we are not manipulating the coil but splitting off one coil from the rest.
When the conversation among the three of us began to wind down, the original person I spoke with asked if I was going to want the conversations had, over the phone, put into a written format (Lol... she knew I would!), and I quickly replied that I did. A summary of those conversations were sent to my e-mail whereby I filed them for future reference, or if needed in the case anyone comes into my shop representing any organization who would question me regarding these regulations.
In my opinion, utilize the documentation Jesse posted and anything that is not explained beyond the point of being "vague", continue to use your judgment and common sense until it is made more clear by the powers that be!
