Forms

Good to know

Both current forms (rev 5-2026 / 6-2026) carry a dedicated 'Submitter agent' block and allow signature by an 'authorized agent' — Missouri is agent-friendly on paper and MOPlants.
Two clocks: license Jul 1–Jun 30 (late after Jul 31, +$25); product registration calendar year, due Jan 1, +50% after Jan 31.
Reduced $25/product tier for ≤$5,000 gross annual sales is 'subject to approval' and needs documentation — ask before relying on it.
Retail-only facilities selling products labeled by a licensed firm need no license.
