New - changes are coming for the upcoming fertilizer license renewal and tonnage reporting term!

Do not submit your renewal materials until the new forms are available. The new versions of the 2024-2025 Fertilizer Tonnage Report and the 2025-2026 Fertilizer License Renewal Application will be posted by August 30, 2025.

Annual Fertilizer Tonnage Report and the fertilizer tonnage fees:

The Agrichemical Cleanup Program (ACCP) surcharge of $0.05/ton of fertilizer is due for fertilizer distributed in Wisconsin from July 1, 2024 to June 30, 2025, in addition to the $0.62/ton tonnage fee. This results in a new overall tonnage fee due of $0.67/ton or a minimum of $29, whichever is greater.
For each licensed location, a separate tonnage report is required. Previously, a business with multiple Wisconsin locations was able to submit a single tonnage report for all facilities. This practice will no longer be available.

License:

The Agrichemical Cleanup Program (ACCP) surcharges are due for every fertilizer license in addition to the $30 license renewal fee:

The ACCP surcharge is $10 for distributors whose facilities are located outside the state of Wisconsin.
The ACCP surcharge is $10 for a facility located in the state of Wisconsin. There is an additional ACCP surcharge of $12.50 for a facility located in the state of Wisconsin that distributes bulk fertilizer.

License numbers will change to a six-digit number (e.g. 654321). This replaces the previous 30-012345-012345 license number format.

Online licensing and tonnage reporting: New this year, you will be able to apply online for your annual Wisconsin fertilizer license; report annual fertilizer tonnage; and pay fees on the Wisconsin Department of Agriculture, Trade and Consumer Protection website.

To distribute fertilizer products in Wisconsin you must:

Details about the surcharge are available here.
Annually report tonnage and pay tonnage fees of $0.62/ton of fertilizer distributed in Wisconsin between the previous July 1 to June 30. Tonnage is reported when you renew your license in September. A $0.05/ton ACCP surcharge will bring the total tonnage due to $0.67/ton.

Non-Agricultural and Special-Use Fertilizer Permits

If you distribute low-analysis fertilizers, you will need either a non-agricultural or special-use permit. Low-analysis fertilizers have less than 24 percent N-P-K. These permits remain in effect until you change the product's label or formulation. The permit fee is $25/permit, a one-time charge.

Non-agricultural fertilizers are used on gardens, lawns, golf courses, greenhouses and nurseries and other non-farm uses, and for research.
Special-use fertilizers are for product labeled for remedying nutrient deficiencies unique to certain crops or local areas
You may also need a soil or plant additive license and permit if the fertilizer product also include substances that claim to improve plant growth, crop yield or quality, or soil properties.
