Sadly I know people who started bucket cells before the yanks, and made product for pyro. It's so much simpler to make chlorate than to jump to hoops and drive the miles. It's harder to make perc, so I hope people will be careful about the limitations and incompatibilities of chlorates. I see the downside of the precursor regs being DIY and some unintentional bangs when people try to sub chlorate into a nitrate formulation.
I used to work in a multi KA plating plant so I've seen the issues with electrochemical production, lots of others have even less experience.
