Do I need EPA registration for my fertilizer product?

Plain plant nutrients usually require state fertilizer registration through AAPFCO-aligned programs, not EPA. But if your product claims to control pests, regulate plant growth, or makes a biostimulant pest-related claim, it can trigger federal EPA registration. A qualified formulation chemist flags this early. Many ag chemists on AJ Cosmo Labs can tell you which track your claim falls under before you spend on testing.
