A wheel that leaves your dock and lands on a kitchen counter in another state plays by a different set of rules than one sold at your farm gate. Federal law takes over, and the cold chain becomes part of your food safety plan. None of it is out of reach for a small creamery. This guide covers what FDA expects, how to pack and ship without spoiling your work, and how to label and track every wheel.
Why crossing a state line changes the rules
Picture a farmstead maker whose cheddar just got an order from another state. It feels like one more sale. Legally, it is a different game.
Inside your state, you answer mainly to your state dairy regulator, who licenses your plant and inspects it. Once a package crosses a state line, it enters interstate commerce, and FDA’s authority under the Federal Food, Drug, and Cosmetic Act applies to the product directly. The clearest example is pasteurization. Federal rules bar anyone from shipping milk or milk products in final package form across state lines unless they are pasteurized, or unless another procedure written into the regulations applies, such as the curing rules in Part 133 for certain cheeses (21 CFR 1240.61). We will get to that exception in a moment.
Cottage food laws will not carry you across that line. They exist to lighten the load for home bakers and jam makers, and they generally cover foods that do not need temperature control to stay safe. Cheese rarely fits that description. Most states also keep online cottage food sales inside their own borders, according to the National Agricultural Law Center. A few states have widened their rules, and North Dakota even allows out-of-state sales, but cottage food status is the wrong tool for shipping cheese. Your foundation is your state dairy license, and everything below builds on it.
Your FDA starting kit: registration, exemptions and the 2026 renewal
Here is where many makers get the first fact wrong. Registering with FDA is not triggered by shipping across state lines. FDA’s registration Q&A says a domestic facility must register whether or not its food enters interstate commerce. What matters is whether you are exempt.
Two exemptions matter most to small cheesemakers. The first is the farm exemption, and it is narrower than it sounds. The same Q&A says a dairy farm that processes its milk beyond what is consumed on the farm is a “mixed-type facility” that has to register. Making cheese is processing. The second is the retail food establishment exemption. Under FDA’s definition, an operation qualifies when the annual value of its sales directly to consumers is larger than its sales to all other buyers, and direct sales include mail, catalog and internet orders. A creamery that sells mostly through its farm store, farmers markets and its own web shop may be exempt. The same creamery can lose that status the year a grocery chain or distributor pushes wholesale past the halfway mark. Check the ratio every year, and confirm your status with FDA or your state regulator before you assume. Being exempt from registration does not exempt you from state licensing, or from FDA’s authority over food that is adulterated or misbranded.
If you do register, it costs nothing. FDA’s fact sheet states there is no fee for registration or renewal, so be wary of any site that asks you to pay. FDA uses a DUNS number as the unique facility identifier, so get one before you start. Then mark the calendar. Registrations must be renewed every two years, between October 1 and December 31 of each even-numbered year. 2026 is a renewal year, and the window opens October 1.
Registration is also where the Food Safety Modernization Act (FSMA) enters. Its preventive controls rule asks registered facilities to keep a written food safety plan built around a hazard analysis. Very small businesses get relief. If your average annual sales of human food fall below an inflation-adjusted threshold, about $1.41 million using FDA’s 2025 figure, you are a “qualified facility.” You skip the hazard analysis and preventive controls, but you must file a short attestation, Form FDA 3942a, every two years in the same October-to-December window, and you must still follow current good manufacturing practices, the basics of sanitation, hygiene and plant upkeep. Put both filings on one reminder for October and do them in a single sitting.
Raw milk cheese and the 60-day rule
If you make raw milk cheese, the rule that decides whether you can ship it is the 60-day rule. FDA states it plainly: cheese made from unpasteurized milk must be aged at not less than 35°F for at least 60 days, in accordance with Part 133. Two catches are worth knowing.
First, the alternative to pasteurization is written variety by variety. Penn State Extension notes, for example, that Colby may be made from raw milk if aged this way, while Monterey Jack must be made from pasteurized milk. Check the standard for each cheese you make, and ask your state regulator about styles that have no federal standard. Second, sixty days is a legal line, not a safety guarantee. In its 2014 to 2016 sampling of raw milk cheeses aged 60 days, FDA tested 1,606 samples, most of them imports, and found Listeria monocytogenes in 10 and Salmonella in 3. The agency also noted that 60 days of aging may not eliminate or adequately reduce E. coli O157:H7 and Salmonella. Read that as a reason to keep milk quality and plant hygiene tight. For the craft side of this choice, see our comparison of raw versus pasteurized milk for cheese.
In practice, treat the 60 days as something you must be able to prove. Date every make, keep temperature logs for your aging room, and never release a raw milk wheel to an out-of-state order on day 59. Some states add their own labeling or sales rules for raw milk cheese, so check your state and the destination state before the box goes out.
Soft and bloomy rind cheeses versus aged hard cheeses
Not every cheese asks the same amount of you. Listeria monocytogenes is the pathogen cheesemakers worry about most, because unlike many bacteria it can keep growing at refrigerator temperatures. Soft, high-moisture cheeses, such as fresh chèvre, bloomy-rind rounds and washed-rind styles, give it more to work with. A dry, salty, well-aged cheddar or Parmesan gives it far less. FDA draws the same line in its Food Traceability List. Fresh soft, soft-ripened, semi-soft and raw milk cheeses other than hard cheese are on it. Hard cheeses are not. If you need a refresher on the families, our guide to cheese categories covers them.
This summer showed why the distinction matters, and why pasteurization is not a complete answer. FDA and CDC investigated a Listeria outbreak linked to soft cheese, including requesón, from a Maryland dairy. Fifteen people were sickened in four states and Washington, D.C., 14 were hospitalized and one died. The dairy expanded its recall to every cheese it made after environmental samples from its facility also tested positive. CDC noted that soft cheeses made from pasteurized milk can still become contaminated during cheesemaking. FDA closed the investigation on August 26.
The lesson for artisan makers is that risk lives in the room as much as in the milk. Drains, brine tanks, cutting tables and ripening racks all need a cleaning and swabbing routine, and the softer your cheese, the more that routine matters. It also changes how you ship. Soft cheeses get colder packs, faster service and tighter shipping windows. Aged hard cheeses forgive a longer trip and a slower carrier. Many makers send soft cheeses only overnight, or only to nearby zones.
Cold-chain logistics: packing, speed and the day you ship
Are you a “shipper” under the sanitary transportation rule?
FSMA’s Sanitary Transportation of Human and Animal Food rule covers shippers, loaders, carriers and receivers. FDA defines a shipper as the person, such as the manufacturer, who arranges for a carrier to move the food. That makes you the shipper every time you hand a box to a carrier. Businesses with average annual revenue below an inflation-adjusted threshold are not covered. That figure was $704,950 for 2025, up from the original $500,000. If you are covered, you need written procedures to make sure food that requires temperature control for safety travels under adequate temperature control.
Even below the line, treat the rule as your standard. Soft, high-moisture cheeses are the likeliest to need that control, and a customer who opens a warm box will not care about your revenue. Ask your regulator how your styles are classified.
Build the box
Follow the order the American Cheese Society recommends, as relayed by Penn State Extension: box, liner, crinkle paper, cheese, more crinkle, more cheese, crinkle again, then ice packs on top, with harder cheeses at the bottom and softer ones above. Penn State’s starting ratio is one pound of gel pack for every two pounds of product, and the packs need enough time in the freezer before you use them. FedEx’s perishables guidance calls for an insulated foam container with walls at least 1.5 inches thick, an outer corrugated box, a watertight plastic liner at least 2 mil thick, and absorbent material for condensation. It says gel packs hold temperatures in the 34°F to 50°F range, and that dry ice requires hazardous materials paperwork. Cheese does not need to be frozen, so skip the dry ice.
Eco-friendly insulation, such as recycled denim or paper-based liners, can work, and many customers prefer it. Match its performance to your routes with a test before you switch. Penn State recommends sending test shipments to yourself, friends or family, and it puts the arrival target for soft cheeses at or below refrigeration temperature, which it gives as 35°F. FDA’s Food Code sets the cold-holding limit at 41°F. Slip an inexpensive temperature data logger into a few test boxes, one in July and one in January, and let the numbers tell you whether your pack-out holds up.
Speed, cost and the no-ship-after-Wednesday rule
FedEx recommends next-day services for perishables and offers no temperature guarantee. Its advice for anything slower is blunt: your packaging and coolant must protect the product for at least 24 hours beyond the delivery commitment time. Penn State likewise suggests overnight over two-day. Overnight costs more, but a spoiled box costs more still, in replacement cheese, a second shipment and a customer you may not win back. Build the higher cost into your prices and shipping fees. Our guide to pricing artisanal cheese for profit shows how to fold it in.
Then there is the calendar. FedEx suggests shipping Monday through Wednesday so packages do not sit in a hub over the weekend. Make that a hard rule. Orders placed Thursday through Sunday wait in your cooler and ship Monday, and your checkout page should say so before the customer pays. From May through September, FedEx also suggests Hold at Location or Signature Required so a box is not left on a hot porch.
The table below turns all of this into starting points for each season. They are rules of thumb built from the sources above and common practice, not regulatory standards, so confirm them with your own test shipments.
| Conditions | Carrier service | Gel pack starting point | Ship days | Add this |
|---|---|---|---|---|
| Cool weather (winter, cold at both ends) | Overnight for soft cheeses. Two-day only for aged hard cheeses, and only if tested. | 1 lb gel per 2 lb of cheese (Penn State baseline). Keep a paper barrier between packs and cheese. | Mon to Wed (Mon and Tue for two-day) | Watch for freezing on very cold routes. Soft cheese that freezes and thaws loses its texture. |
| Mild weather (spring, fall) | Overnight. Two-day only for aged hard cheeses. | 1 lb gel per 2 lb of cheese. Confirm with a temperature logger. | Mon to Wed | Pre-chill the cheese and freeze the packs solid before packing. |
| Hot weather (summer, or about 80°F and up at either end) | Overnight only. | Start near 1 lb gel per 1 lb of cheese, then adjust from logger results. | Mon and Tue preferred | Hold at Location or Signature Required. Use 1.5-inch foam or a liner you have tested. Pause soft cheese to heat-wave destinations. |
Labels that keep you out of trouble
FDA’s Food Labeling Guide lists what every package needs. Start with the statement of identity, which is the common name of the food, such as “Cheddar Cheese.” Add the net quantity of contents in both U.S. customary and metric units, for example “Net Wt 8 oz (227 g).” List the ingredients in descending order by weight, for example “Pasteurized Milk, Cheese Cultures, Salt, Enzymes.” Finish with the name and place of business of the manufacturer, packer or distributor, using “Distributed by” or a similar qualifier if you are not the manufacturer.
Milk is a major food allergen, and every cheese contains it. Per FDA’s allergen labeling Q&A, you can declare it in one of two ways: name it in the ingredient list, as in “pasteurized milk,” or add a “Contains: Milk” statement immediately after or next to the ingredient list, in the same type size. If you use a Contains statement, it must list every major allergen in the product. Watch the add-ins in flavored cheeses. Tree nuts, wheat-based ingredients and sesame in a crust or wash all have to be declared, so check every component of every flavored wheel.
Nutrition Facts panels are required unless you qualify for the small business exemption. That means fewer than 100 full-time equivalent employees and fewer than 100,000 units of that product sold in the U.S. in 12 months. You must file a notice with FDA every year, and FDA does not remind you. Any nutrient content claim or health claim on the label voids the exemption. Finally, add “Keep Refrigerated” to the cheese label and “Perishable: Refrigerate on Arrival” to the outside of the box, as Penn State suggests, and check whether your state or the destination state requires a raw milk statement.
Lot codes and traceability: the recall you hope never to run
A lot code is a short identifier that ties a wheel to the day and vat it came from. A simple format works: make date plus vat number, such as 260914-2 for the second vat made on September 14, 2026. Put it on every label. Then copy it onto the invoice and packing slip along with the customer’s address, ship date, product and quantity. That is exactly what Penn State advises for recall management. Keep a lot log beside it that records the milk source, culture and rennet lot numbers, make date, aging room and release date.
Test the system before you need it. Pick one lot and time how long it takes to list every customer who received it. If the answer is more than an afternoon, fix the paperwork now. If you are a registered facility, remember the Reportable Food Registry, which requires a report when there is a reasonable probability that a food will cause serious adverse health consequences or death.
Traceability rules are also tightening. FDA’s Food Traceability Rule requires firms handling foods on the Food Traceability List to keep records built around a traceability lot code. The compliance date has been extended to July 20, 2028, and Congress directed FDA not to enforce it before then. Soft cheeses are on the list and hard cheeses are not. Under the rule, “shipping” does not include selling directly to a consumer, so your online orders fall outside it. Your wholesale buyers and retailers will not. Building good lot codes now means you will already be compliant when the deadline arrives. If you are weighing storefront options, our look at what small creameries need from an online marketplace is a useful companion.
Print the Order-to-Door checklist
Rules only work if they reach the packing table. We turned this guide into a one-page Order-to-Door checklist your staff can print, tape up and initial on every shipment, from the Monday-to-Wednesday check to the lot code on the packing slip.
The short version
Crossing a state line does not need to scare you. Confirm your state dairy license, work out whether you register with FDA or qualify for an exemption, and put October’s renewal on your calendar. If you make raw milk cheese, prove your 60 days. Treat soft and bloomy-rind cheeses with more care than aged hard cheeses, pack to a tested standard, ship Monday through Wednesday, and label every wheel with a lot code you can trace in an afternoon. Those habits protect your customers and the reputation you have spent years building.
