What's covered vs. what needs a different path

Covered here

  • Whole grains (corn, wheat, oats, rye) sold dry and unprocessed
  • Milled flour and cornmeal from your own or purchased grain
  • Grain blends, grits, and cracked-grain products
  • Direct sales at markets, on-farm, online, and by mail

Needs a different path

  • Pre-mixed baking kits with a perishable add-in (dairy, fresh eggs)
  • Grain products sold wholesale into a mill, bakery, or grocery supply chain
  • Any grain product that has been cooked and requires refrigeration
  • Feed-grade grain sold for animal consumption (falls under feed/commercial feed rules, not food cottage food)
How to get compliant
A

Keep it dry and food-grade

Whole grains and milled flour are textbook non-TCS dry goods and fit squarely into Iowa's cottage food exemption, with no license needed for direct sale.

B

Label the mill run

Include your name and contact information, the common name (e.g., "stone-ground yellow cornmeal"), full ingredients if it's a blend, and the exemption statement.

C

Separate food-grade from feed-grade

If you also sell grain as livestock feed, keep that inventory and labeling distinct — feed products fall under Iowa's Commercial Feed Law, not the food cottage food exemption.

Frequently asked
Do I need a milling permit to sell my own stone-ground flour?

No specific milling permit exists under Iowa's food rules for direct-to-consumer dry flour; follow the standard cottage food labeling and sales requirements instead.

Can I sell the same grain as both food and animal feed?

Yes, but keep the two product lines and labels clearly separate, since feed intended for animals is regulated under an entirely different law (Commercial Feed Law) than grain sold as human food.

What if my flour blend includes a shelf-stable dried egg or milk powder?

Dry, shelf-stable powdered dairy or egg ingredients can generally be listed as ingredients in a dry mix, but double-check the finished product doesn't become TCS and that all allergens are flagged.

Is there a limit on how much flour I can sell per year?

No sales cap under Iowa's cottage food law — the product type, not the volume, determines eligibility.
