Pesticide Tolerances; Implementing Registration Review Decisions for Certain Pesticides; Terbacil, et al.
EPA finalized pesticide tolerance changes for terbacil and other pesticides, which may affect maximum residue limits on raw agricultural commodities used in dietary supplements. This could impact ingredient sourcing and require updated testing or supplier documentation.
Aforeworn detected this change in the Dietary-Supplement Labeling (FDA) space on July 5, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated Low urgency. Supplement brands, contract manufacturers, and ingredient suppliers using botanicals or agricultural ingredients that may be treated with terbacil or other listed pesticides. should confirm how it applies to their specific situation before acting. There is a time constraint attached: No immediate deadline; tolerances are effective upon publication (Feb 20, 2026). However, compliance should be ensured before next growing season or procurement cycle.. Acting after that point can mean penalties, a lapsed licence, or lost eligibility — exactly the kind of surprise Aforeworn exists to prevent. Aforeworn monitors Dietary-Supplement Labeling (FDA) continuously and turns every detected change into a plain-English briefing like this one, so you always know first. Forewarned is forearmed.
