For what it's worth many things are like this. It's the same thing with genetically engineered products, also under FDA purview. There is 0 mandatory oversight. If you have the clearance to sell a potato, then you can produce any engineered potato you like and sell it with 0 oversight, testing, or additional requirements. All the FDA offers is a purely voluntary opt-in consultation. [1]
Perhaps unsurprisingly this [2] was the head of the FDA under our last president. He was appointed a newly created executive role, not entirely jokingly referenced as the 'czar of foods.' A Monsanto vice president and lobbyist whose career highlights included arguing that companies should be allowed to knowingly allow at least a very small amount of carcinogenic chemicals into foodstuffs. Seriously, that was the head of the US Food and Drug Administration for nearly 8 years.
