The rule library, as data
Every rule we publish, in JSON and CSV, with the official source and the date we last read it inside the file. Free, attribution only. Take it and check us.
Why we give it away
Because the alternative is worse. The four consultancies in this market publish nothing: you call, they quote, and you never see the statute behind the answer. The one free library that exists belongs to the industry association, carries no source per rule and no review date per rule, and its last declared modification is from 2023.
We would rather be the file everyone checks against. If you find us wrong, we would like to know: write to info@fertilabel.com and the correction gets published with its date, like the two we have already made.
What is in it, and what is deliberately not
Per state: agency, licence fee and period, product registration fee and unit, inspection fee per ton, minimum fee, reporting frequency and due dates, late penalty, filing portal, and the official sources.

The data is free. What we sell is not having to act on it yourself: one calendar, prefilled forms, fees to the cent. You stay the registrant and you file.

This is not legal advice, and it is not a substitute for the state agency. Confirm every figure before you file; the obligation is the registrant's.
