Can you sell jam from home in Iowa without a license?
Updated

Yes, if every batch passes a meter reading. Iowa's licensing chart lists shelf-stable jams, jellies and fruit butters as cottage foods you may sell directly to consumers with no license or inspection [2]. The condition is testing: the state expects a soluble solids reading to support the product's name and a pH or water activity reading to show it is shelf stable, and its rule requires every batch of home-canned fruit to be measured with a meter, with the records available on request, even at your market table [2] [3]. Freezer jam and any sale to a shop need a home food processing establishment license instead [2].
The readings Iowa expects for every batch
Iowa's rule for home-canned pickles, vegetables and fruits sets four conditions [3], and the licensing chart requires pH or water activity testing for shelf-stable jam [2], so plan on meeting all four:
- Measure each batch with a pH meter or a water activity meter.
- The finished product must read pH 4.60 or lower, or water activity 0.85 or lower.
- Mark each container with the date it was processed and canned.
- Give your batch testing records to the regulator on request, including at the point of sale.
The licensing chart adds a second test for jam specifically: soluble solids testing "for product identity" [2]. A product sold as jam or jelly must meet the federal standard of identity, which turns on the soluble solids (mostly sugar) in the finished product. A refractometer reading is how you show it. What 65 percent soluble solids means explains the numbers and how to take the reading, and measuring pH covers meters and calibration.
Keep the readings in a batch log next to the canning date. A simple format is on record keeping. A batch that misses the pH or water activity limit is not a cottage food.
Which preserves fit
| Product | Route in Iowa |
|---|---|
| Shelf-stable jam, jelly or fruit butter | Cottage food, direct to consumers; soluble solids and pH or water activity testing [2] |
| Jam, jelly or fruit butter that needs refrigeration or freezing (freezer jam) | Not a cottage food; home food processing establishment license [2] |
| Any jam sold wholesale or for resale | Home food processing establishment license [2] |
| Low-sugar or no-sugar jam | Not listed separately [2]; it must still pass the shelf-stability test, and it may not meet the standard for the name "jam" (see what to call it) |
| Pepper jelly | Not listed by name [2]; the batch meter rule applies to all home-canned produce [3]. Ask the Department |
| Pumpkin butter | The chart's fruit butter row does not name it [2]; there is no tested home canning method [4] |
What goes on the jar
The rule requires [3]:
- your name, plus an address, phone number or email;
- the common name of the food;
- ingredients in descending order of predominance;
- the statement "This product was produced at a residential property that is exempt from state licensing and inspection.";
- an allergen statement naming each major food allergen present;
- for home-canned products, the date processed and canned.
Net weight and the rest of the federal baseline are on federal labeling for jam.
Where and how you can sell
The food must go from you directly to the consumer [1] [3]. The only food establishment where cottage food may be offered is a temporary food establishment you operate yourself, such as your own market stand [1] [3]. The statute allows sales in person or remotely, by phone or internet, with delivery by you, an agent or mail [5]. No state source found addresses sales to buyers outside Iowa, and no sales cap is stated for cottage food [1].
The home food processing establishment license
To sell freezer jam, or to sell any jam to a shop, cafe or other reseller, Iowa routes you to a home food processing establishment license under Iowa Administrative Code chapter 481-34 [2]. The Department's chart is the tool for deciding which you need; its link sits on the cottage food page [1]. The license fee and sales limit were not reconfirmed in October 2026, so ask the Department.
DIAL, the agency for both routes
The Iowa Department of Inspections, Appeals, and Licensing (DIAL) oversees cottage food and home food processing. Its Cottage Foods page is reference [1]; the law is Iowa Code 137F.20 [5] and the rule is 481-30.13 [3]. The rules above were last verified in October 2026. To keep the per-batch readings in one place, use the batch log.
