The Effects on USP <800>
Even though USP Chapter <800> becomes official on December 1, 2019, it has been stated by USP that it is informational and not fully applicable due to the postponement and pending resolution of the <795> and <797> chapters.
However, some states will be enforcing USP <800> in its current form as of December 1st. In these states, each entity has the option of deciding which version of the chapter they will be inspected under.
Because some states are choosing to enforce all these new chapters, it is important that each site look to their state regulating bodies for guidance.
