Selling Farm Products: Permit Basics

Why do permit rules differ so much?

Food and farm sales are regulated by several layers of government, with different agencies for plants, eggs, dairy, meat and prepared foods. States set many of the rules, and counties and towns add their own. Extension guides from Wisconsin, Vermont and Oregon show how different the lists can be from state to state.

Never rely on what a neighbor in another county or state told you. Rules change, and exceptions often depend on small details such as volume, where you sell and how you label.

A good first step is to write your product list in three columns: what you make, how you make it and where you hope to sell it. Many permit questions turn on the process, such as whether you only grow and pick something or whether you wash, cut, cook, package or preserve it. Each added step can bring a new set of rules.

Which offices should you contact?

Start with your state department of agriculture, which often has a beginning farmer or food safety contact, and your county extension office, which can point you to the right agency. Then ask your county or city health department about food rules, and your planning office about zoning for sales on your land. Ask your state revenue office about sales tax registration.

Write down who you spoke with and what they told you, and ask them to send it by email when possible.

• State department of agriculture: product rules, licensing, labeling
• Health department: food handling, kitchens and sales to the public
• Planning and zoning office: signs, stands and customers on your land
• State revenue office: seller registration and sales tax
• Your insurance agent: coverage for sales and visitors

What questions should you ask for each product?

For each product, ask whether a license or permit is required, whether any exemption applies to small sellers, what labeling is needed, what limits exist on where and how you can sell, and what inspections or records are required. Ask whether the rule differs for selling at a farm stand, a market, to a restaurant or online.

Raw produce, eggs, meat, milk and prepared foods follow different tracks, so ask separately. If a rule uses a sales volume limit, ask how it is measured.

Ask whether any exemption has a catch, such as a cap on sales, a limit on where you sell or a requirement to label products in a particular way. Exemptions usually come with conditions, and losing track of a condition can put an exempt seller out of compliance without any warning.

What about labels, records and weights?

Many products must carry labels with specific information, and scales used for selling by weight may need to be certified or inspected by a state weights and measures office. Ask the agriculture department what applies. Keep sales records, receipts and any required logs, since they help during an inspection and at tax time.

Keep a file for each product that records what the agency told you, the date, and copies of forms and permits.

How does the way you sell change the rules?

Selling at the farm, at a market, through a share or subscription, to stores or restaurants, or online can each bring different requirements. Shipping across state lines adds federal and other state rules. Do not assume that a rule for one channel applies to another.

Farmers markets and buyers often add their own requirements, such as insurance or proof of permits, on top of the law.

What should your first week look like?

List every product you hope to sell and the way you plan to sell it. Call your extension office to learn which agencies cover each product, then contact those agencies with your list of questions. Keep your sales small until you have answers, and do not advertise something until you know it is allowed.

Review your permits yearly, since fees, renewals and rules change. Keep everything in your records file.

Remember that selling can change your other obligations. Insurance, taxes, zoning and even your land use classification may be affected, so tell your agent and your tax professional when you begin selling, and ask each what you need to do differently. If you are unsure whether your activity needs a permit, ask anyway. Agencies generally prefer a question before a sale to a complaint afterward, and a documented inquiry shows good faith. Keep selling at a small scale or hold off until you have heard back, and do not rely on a verbal comment from someone who may not speak for the whole agency.
