Earlier quoted context omitted.
According to the ROI ( https://www.federalregister.gov/documents/2026/07/06/2026-13... ), the threshold isn't yet fixed but the suggested value would be 1 milligram or 5% of the dry-mass. Doses sold are in grams so this would ban kratom.
Paragraph A,not paragraph B applies to actual kratom leaf.
Indeed, thanks for catching that. No maximum for an actual kratom leaf but leafs cannot be too potent, right?
