Inspection fee
$0.37 per ton · minimum $9 · a statutory floor since 1 July 2025; the rule text we could read (Agr 1106.01) still says 20 cents and $5 - see the open discrepancy. The minimum is due even with zero sales · (RSA 431:6, I)

Open discrepancy — read this before you file. Two official sources for New Hampshire 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 New Hampshire 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 New Hampshire?
New Hampshire 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 New Hampshire tonnage report due?
Semiannual · on or before 30 days following the close of each semiannual filing period · the department's site refused our requests (403), so the period boundaries are NOT VERIFIED and we do not calendar a day · (RSA 431:6, II; Agr 1106.02).
What happens if I file the New Hampshire tonnage report late?
a collection fee set by rule, added to the amount due if not filed within 30 days; amount NOT VERIFIED · (RSA 431:6, II).
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.
