How to get a microbial input registered in the US.
There is no single US registration. Fertilizers and biostimulants register state by state, each with its own control officials. The science travels; the filings don't. Here is the path, state by state.
Scope: Source-backed research aid. Not regulatory advice. Not claim substantiation. Not a safety, compliance, or approval determination. Approvability is decided case-by-case by the relevant state control officials.
The path in five steps
- 01
Verify the organism's identity
Regulators match products by accepted name. Start from the accepted binomial and every synonym on record: the 354 accepted names and synonyms cover the 180 AAPFCO organism groups, and a retired synonym on a label invites questions.
- 02
Pull the accepted claim language
The AAPFCO Biostimulant lens shows the claim statements accepted for your organism, verbatim, including caveats. This is the language state label reviews check against. Start the label from it, not toward it.
- 03
Classify the product in each state
The same jar can be an auxiliary soil and plant substance in California and a commercial fertilizer in Texas. Classification is set state by state, and a pesticidal claim changes the pathway everywhere.
- 04
File where you sell
Registration is state by state: each state's control officials register products separately. The guides below walk each process step by step.
- 05
Plan the ongoing obligations
Tonnage reports, renewals, and re-registrations continue after approval. The Ongoing Compliance lens will track these per state as it connects.

Frequently asked questions
Is there one US federal registration for biostimulants?
No. Fertilizers and biostimulants register state by state with each state's control officials. Only products making pesticidal claims go through the EPA under FIFRA.
What does AAPFCO actually do?
AAPFCO is the association of the state control officials. It publishes model language and the plant biostimulant source data this site is built on. It does not register products. Registration happens in each state.
Can one dossier serve every state?
The scientific core (organism identity, synonyms, claim evidence) travels well. The filings do not: each state has its own forms, review, language, and renewals.
How long does registration take?
It varies by state and product, and agencies revise their queues, so we don't restate timelines. Each guide names the controlling agency to check directly.
Look up your organism before you file.
Every organism record shows its verbatim AAPFCO claim statements, caveats, and citations: the language state label reviews check against.
