The good manufacturing process thing is the only part that would include inspections and that's section 606, which does not apply to small businesses . We're not facilities under that. No registration , no GMP enforcement .
In fact a text search for the word inspection only comes up with records inspection if a product is found to be adulterated , or upon causing a serious adverse health event (i.e., if someone dies or is hospitalized or the like, from your product). Which seems right & proper, and also vanishingly rare.
