Open discrepancy — read this before you file. Two official sources for Montana do not agree on the following, and we will not guess:

Confirm with the agency before relying on it. When we close it, this page changes and the source is cited.

What this means in practice

Every state sets its own calendar, its own fee and its own filing route, and none of them warn you before a deadline passes. In Montana the reporting cycle is semiannual, so the work repeats twice a year for as long as you distribute there.

If you also sell in other states, none of those dates line up. That is the whole problem Fertilabel exists to solve: one calendar, one place, every form prefilled, every fee calculated, and the official source next to every rule so your own team can check it.

Questions

Do I need to register my fertilizer product in Montana?
Montana regulates fertilizer at state level — there is no federal fertilizer registry in the United States. The licence and registration requirements above come from the official sources listed at the foot of this page. Confirm your specific product with the agency: what applies depends on the product type and package size.
How often is the Montana tonnage report due?
Semiannual · due 30 January and 30 July · on or before the 30th calendar day after the end of each reporting period · (ARM 4.12.608).
What happens if I file the Montana tonnage report late?
10% of the amount due, minimum $25 · (MCA 80-10-207).
Does Fertilabel file this for me?
No. We prepare the calendar, the prefilled forms and the fee math, and you submit under your own state account. You stay the registrant of record. We are not a law firm and we do not give legal advice.
