Do You Need a License to Sell Microgreens in Iowa?

Yes, once you cut them.

Iowa Code 137F.4(1) says a person may not operate a food establishment or food processing plant until the appropriate license is obtained. The escape hatch is narrow and it is written into the definitions: 137F.1(9)(c) says a produce stand or facility which sells only whole, uncut fresh fruits and vegetables is not a food establishment.

Read that clause on your own product and the answer falls out. A living tray sold with the crop intact is whole and uncut. A clamshell of harvested greens is neither. So in Iowa the exemption tracks the physical state of the thing you hand over, and harvest is the moment you leave it.

That makes Iowa unusual in a practical rather than a legal way. Several states in this series exempt whole uncut produce. Iowa is the one where the same grower, on the same bench, is exempt on the tray and licensed on the punnet, and can reasonably sell both in a single morning.

Once you are licensed, a second question decides which license: do you own the outlet you are selling into? Section 137F.4(1) puts wholesale to outlets not owned by the commissary owner in the food processing plant category. So the license category is set by ownership and channel, not by volume.

The federal layer applies on top. See the FDA Produce Safety Rule page.

Where the line falls

The dominant-form question is the one to raise early. Iowa contemplates an operation that does not sit neatly in one category and gives DIAL a statutory basis to decide which license governs it, at 137F.5(3). A grower who wholesales on weekdays and sells direct on Saturdays should get that determination in writing rather than picking a category and hoping.

The fee bands, and what they do not do

These come from Iowa Code 137F.6(1)(g) and they are worth reading carefully, because a fee schedule that moves with sales looks like a threshold and is not one. No band exempts anybody. The smallest grower in the state pays $75 and holds the same license as the largest.

That is a different shape from most of this series. Indiana exempts direct sales up to $1.5 million. Tennessee prices by floorspace and risk. Iowa charges by revenue and never lets go. The practical effect is that the fee is almost irrelevant to a small operation: $75 a year is less than a flat of trays, so the decision is which license, not whether the license is worth it.

One consequence catches people out. A grower who plans to work only farmers markets may find the $150 farmers market license costs twice the $75 entry band for a processing plant. The two licenses do different jobs and are not interchangeable, so this is not an invitation to pick the cheap one. It is a reason to describe the actual business to DIAL before assuming the market route is the economical one.

Who actually regulates you

Iowa splits enforcement in a way that matters when you go looking for an answer.

The named local jurisdictions are Johnson County Public Health, Linn County Public Health for Linn and Jones, Scott County Health Department, the City of Dubuque Health Department for the city only, and Siouxland District Health Department for ten northwest counties.

The useful implication: if your plan is wholesale, your regulator is DIAL wherever you are, and a neighboring grower's answer from a county health department may not be about your license at all. Iowa food law also preempts local food licensing and inspection unless a municipality holds an enforcement agreement, so a city cannot invent a second food license. It can still zone you.

Licensing is on 515-725-5342. Plan review is on 515-350-7587, and it is a call to make before you build, not after.

Inspections

Iowa Code 137F.9 prohibits opening or operating a food establishment or processing plant until it has been inspected and licensed, so the first inspection precedes the business rather than following it. Section 137F.10 provides for regular inspection and entry at reasonable hours, and 137F.11 covers complaint inspections.

The statute does not set a single statewide annual frequency in the text reviewed, and no one should promise you one. Frequency is risk based and set by rule. Treat "how often will I be inspected" as a question for the office that licenses you, and expect the answer to depend on what category you land in.

Food safety and water

Iowa layers its own licensing, pre-opening inspection and Food Code framework onto the federal FSMA floor. Section 137F.2 directs DIAL to adopt minimum standards and permits adoption of the FDA Food Code. For harvested greens the operational content is what you would expect: hygienic harvest and packing, cleanable food contact surfaces, protected product, temperature control where the product needs it, approved water, and whatever your license category's plan review requires.

Water. Under the current federal rule, a covered non-sprout farm makes a written, systems-based pre-harvest agricultural water assessment at least once a year, and again after a change that increases risk. It replaced the old uniform testing schedule, so there is no universal test count to hit. Small farm compliance began 6 April 2026 and very small farm compliance begins 5 April 2027. Iowa has published no stricter microgreens-specific water frequency.

The free review. The Iowa Produce Safety Program is a joint IDALS and Iowa State University Extension effort, and it runs a voluntary, free On-Farm Readiness Review. The program contact is John Krzton-Presson, 515-725-1179. A 2018 IDALS announcement described the review as taking under two hours; confirm current scheduling rather than treating that as a guarantee. The program's training also meets the training requirement for fully covered farms.

Federal figures. Check them against FDA, not against a state page. FDA currently publishes $34,324 as the three-year 2023 to 2025 average produce-sales figure below which a farm is not covered, from a $25,000 baseline in 2011 dollars, and $686,476 on the same three-year basis for the qualified exemption. Take both from the column headed "Average 3 Year Value for 2023 - 2025"; the single-year 2025 values printed beside them, $35,247 and $704,950, are a different measure.

Labeling

For packaged microgreens out of a licensed facility, DIAL lists the minimum elements:

Where the responsible firm is not the manufacturer, the address is qualified with "manufactured for" or "distributed by". A single-variety pack normally carries no ingredient list beyond the product identity and no major allergen, which is not a reason to skip the rest.

On "Keep Refrigerated": Iowa publishes no microgreens-specific phrase. The legal duty is the underlying temperature control, not the wording on the bag. Where refrigeration is the safety control, a truthful statement belongs on the pack and should not be omitted. Settle the exact statement with your inspector at plan review.

Tax, and the permit you probably do not need

Fresh microgreens sold as unprepared food are generally exempt from Iowa sales tax: Revenue lists vegetables and vegetable products among exempt food, and says a business selling only exempt unprepared food does not need a sales and use tax permit or have to file returns.

So unlike Tennessee, where registration is required above a monthly sales average even when the product is exempt, Iowa lets an exempt-only seller stay out of the system entirely. The permit becomes necessary once you make taxable retail sales, for instance taxable non-food goods or food sold as taxable prepared food. It is free when you do need it.

A resale or agricultural exemption certificate is not a sales permit. It documents an eligible purchase.

On inputs, Iowa treats raising vegetable plants in commercial greenhouses or elsewhere for sale as agricultural production. The farm guide identifies exempt production inputs including greenhouse production electricity, production-area heating and cooling, qualifying machinery and production water. It is not automatic: you must be able to substantiate eligibility and you normally hand the supplier Exemption Certificate 31-014. Production ends where the product reaches the point of sale or further processing.

Remote sales. Remote sellers and marketplace facilitators become Iowa permit holders at $100,000 in gross Iowa sales, if their sales are taxable.

Business setup

A one-owner grower can operate as a sole proprietor. An LLC is optional and is not a food license prerequisite. If you form one, the Secretary of State's Certificate of Organization is $50, and the LLC biennial report is $30 online or $45 on paper, in odd-numbered years.

An employer must register a UI tax account within 30 days after first paying Iowa wages.

Selling channel by channel

Farmers markets. Whole, uncut fresh vegetables may be sold without a farmers market establishment license. Unpackaged food needing temperature control that was not prepared at the market must come from a licensed facility and needs the appropriate license to be sold there. The farmers market license is $150 a year, must be applied for at least three days before the event with two weeks recommended, is valid only at farmers markets, and a separate license is needed for stands operated simultaneously.

Read Iowa Code 137F.8 before you rely on a market organiser: each vendor is solely responsible for obtaining and maintaining any license they need. The market cannot carry it for you. Markets can and do add their own vendor applications, insurance and product rules on top, as private terms.

Restaurants. This is wholesale to an outlet you do not own, so the statutory answer is a Food Processing Plant license. DIAL describes that category as operations that manufacture, package, label or store food for people to eat and do not sell direct to consumers. Apply at least 30 days before operating, hold the license before opening, and complete plan review. Expect the buyer to want consistent invoices and lot records, refrigerated delivery and label information regardless of what Iowa requires.

Grocery. Beyond the law, buyers commonly want a vendor packet, a UPC or GTIN or internal item code, an insurance certificate, product specification with shelf life and temperature data, lot coding and dependable delivery terms. No Iowa source publishes a universal grocery buyer checklist or insurance limit, so get the chain's written vendor requirements. DIAL can answer the license and inspection side only, never a buyer's procurement terms.

Online. There is no online carve-out. The product must still be lawfully produced, labeled, protected and held at temperature. Crossing a state line adds the destination state's rules and does not convert Iowa food into cottage food.

Home growing and zoning

There is no single Iowa home occupation rule. Cities and counties set land use, and while Iowa food law preempts local food licensing and inspection absent an enforcement agreement, that does nothing about zoning, building, fire, traffic, signage or home occupation review.

Get the zoning determination for the actual parcel before you install racks. As a concrete example of what local can mean, unincorporated Des Moines County lists a $150 home occupation special use permit, and says its permit material applies only outside cities, directing properties in Burlington, West Burlington, Mediapolis, Danville and Middletown to those cities instead. That figure is one county's, not a statewide fee.

A commercial kitchen is not automatically triggered by growing microgreens, because raw produce is not cooked food. A dedicated or licensed facility is triggered when the activity becomes a licensed establishment or processing plant: handling outside the whole and uncut exception, wholesale, or anything needing plan review. Do not build a home packing room before asking DIAL whether it can meet the applicable facility and Food Code standards.

Right to farm is not a permit or a zoning exemption. It can matter in a nuisance dispute involving a qualifying agricultural operation. It does not authorize an unlicensed food facility, override a home occupation rule, or remove Food Code duties, and whether an indoor home operation meets every statutory condition was not established here.

Insurance

Iowa's food license pages do not list general product liability insurance as a condition of a Food Processing Plant, Retail Food Establishment or Farmers Market license. So cover is sound risk management rather than a verified statewide licensing mandate.

If you hire, payroll and UI registration become mandatory within 30 days of first wages. Workers' compensation and employment insurance duties are fact specific and worth checking with the Iowa Insurance Division before you take anyone on.

Restaurant and grocery contracts commonly ask for commercial general liability and product and completed-operations cover, often naming the buyer as additional insured, sometimes with recall cover, certificates, indemnity, lot traceability, cold chain specifications and audit rights. Iowa publishes no mandatory limit for those contracts, so treat a requested limit as a commercial term and price it into the account rather than promising a universal figure.

Legislation to watch, carefully

In the 2026 session, HF 2767, "Home Food Processing", passed the Iowa House 89 to 0 on 27 April 2026. The official vote record proves House passage and nothing more. Senate action, final text and enactment were not verified here, so treat it as pending rather than as current law. It concerns home food processing, and it is not a confirmed microgreens exemption.

The related history is that HF 2431, effective 1 January 2023, replaced the former annual sales limitation in the cottage food rules with broader but still non-temperature-controlled, direct-to-consumer, labeled rules. That is why there is no current cottage food sales cap published. None of it makes microgreens cottage food.

What Iowa does not publish

The market

Iowa is a dispersed statewide market rather than one dense metro. The practical launch zones are Des Moines and West Des Moines, Iowa City and Coralville, Cedar Rapids, Waterloo and Cedar Falls, Dubuque, the Quad Cities and Sioux City, where restaurants and higher-frequency direct buyers concentrate.

That shape favours short refrigerated routes and a planned recurring delivery day over statewide individual shipping. Competition comes from established market produce vendors, greenhouse growers and regional specialty distributors, and microgreens work here when the grower supplies dependable chef-friendly mixes or living trays rather than assuming novelty sells itself.

There is a strategic reading specific to Iowa's rules. Because the exemption attaches to the living tray and the license attaches to the cut product, a grower can genuinely test the market unlicensed on trays, then license deliberately when the cut product justifies $75 a year. Few states let you stage it that cleanly. Validate demand by calling 15 to 20 target restaurants and retailers in one metro before you buy capacity.

Frequently Asked Questions

Q: Do I need a license to sell microgreens in Iowa? A: For cut greens, yes. Iowa Code 137F.4(1) requires the appropriate license before operating, and the produce exception at 137F.1(9)(c) reaches only a stand selling only whole, uncut fresh fruits and vegetables.

Q: So a living tray is exempt? A: It is the strongest case for the exception, because it is whole and it is uncut, which is the entire test. Cut greens lose the fact the exemption is built on. Get DIAL's product-specific view in writing before you build a business on it.

Q: Which license do I need? A: It depends on who owns the outlet. Wholesale to outlets you do not own is expressly a Food Processing Plant license under 137F.4(1). A fixed direct-to-consumer retail premises is a Retail Food Establishment. If you do both, ask DIAL to decide your dominant form of business under 137F.5(3).

Q: Is there a sales figure that keeps me exempt? A: No. The $75, $150, $300 and $500 amounts are annual fee bands set by gross sales under 137F.6(1)(g). Every band still holds the license.

Q: Can I use the cottage food law? A: No. Iowa cottage food is limited to home-made food that needs no temperature control, sold direct by the producer. Refrigerated harvested greens fail both halves, and raw produce is not a home-produced processed food in the first place.

Q: Do I need a sales tax permit? A: Probably not, if you sell only exempt unprepared food. Iowa Revenue says such a business need not obtain a permit or file returns. That changes the moment you sell anything taxable.

Q: Who inspects me? A: DIAL in 68 counties, one of ten local health departments in the other 31. But if you hold a food processing plant license, DIAL is your regulator in all 99.

Q: When do I call about a build? A: Before it. Both retail establishments and processing plants need plan review, and 137F.9 bars opening before inspection and licensing. Plan review is 515-350-7587.

Final thoughts

Iowa asks a question you can answer by looking at what is in your hand. Is this whole and uncut? If yes, the produce exception is live. If you cut it, you are licensed, and the only remaining question is which license, which turns on whether you own the outlet.

Three things to carry. Get DIAL's written view on living trays before you build a business on the exemption, because the clause is clear but your product's classification under it should be on paper. Do not read the fee bands as thresholds; there is no figure to stay under, and at $75 a year for a small operation there is not much reason to try. And raise the dominant-form question early if you intend to wholesale and sell direct, because Iowa gives DIAL the statutory call and you want that answer before you plan around a category.

If something here does not match what DIAL told you, report it and it gets corrected. A page that is wrong about a rule is worse than no page.
