Can you mail food? Yes, through USPS, but only food that will survive the trip without spoiling and only when it is packed to meet postal rules. Foods that keep at room temperature, such as cookies, candy, and sealed snacks, are the easy cases, while fresh and frozen items are allowed in some forms and banned in others.
The rules come from USPS Publication 52, which covers perishables in its chapter on special handling. You are responsible for following USPS, federal, and state law, so the details of what you send matter as much as the box it goes in.
Can you mail food through USPS and what is off limits?
USPS treats food as mailable unless a specific rule says otherwise. The main rule is that anything which spoils before it can arrive is nonmailable. That one sentence decides most cases.
Publication 52 says fresh fruits and vegetables are nonmailable unless they are in a dry condition. Dry here means not wet, and it does not mean dried fruit. Dried fruit is a separate item and ordinary packing rules apply to it.
Eggs, meat, and live plants each have their own section. Eggs and meat are explained below. International mail has a separate perishables section, and it is stricter.
Which foods are easiest to send?
Choose food that stays safe and intact for several days at room temperature. Slow transit, warm trucks, and a mailbox in summer are all realistic. If you would not leave it on a counter for three days, do not mail it plain.
Good candidates include hard cookies, brownies, bars, wrapped candy, crackers, nuts, coffee beans, tea, jerky packaged to meet USDA rules, and sealed jars of jam. Soft frosted cakes, cream filled pastry, and cut fruit are poor candidates.
| Food type | Can you mail it? | How to ship it |
|---|---|---|
| Cookies, brownies, bars | Yes | Wrap in layers, pack tightly in a tin or sturdy box, and cushion the corners. |
| Candy and chocolate | Yes | Add a cold pack in hot weather and avoid weekend delays. |
| Packaged snacks, coffee, tea | Yes | Keep factory seals intact and use a box sized to the item. |
| Sealed jars and cans | Yes | Wrap each jar alone and fill every gap so nothing shifts. |
| Eggs | Yes, domestic only, if cushioned | Cushion every egg and pack to survive handling. |
| Meat and meat products | Domestic only, if USDA rules are met | Seal and contain leaks. Dry ice is allowed within limits. |
| Fresh fruits and vegetables | Only if dry | Anything that rots in transit is nonmailable. |
| Frozen food | Yes, with dry ice or ice packs in some cases | Use insulation, a fast service, and a short route. |
Two worked examples
Example one is a dozen oatmeal cookies going from Ohio to Texas. They keep at room temperature, so no coolant is needed. Wrap them in two stacks, tin them, cushion the tin in a box, and send by Priority Mail, which is the easiest form of the question.
Example two is a frozen casserole going to a family member three states away. Freeze it solid, seal it, and place it in a foam cooler with a liner and gel packs. Ship Monday with the fastest service and tell the recipient to expect it, because without those steps it will thaw and become unsafe.
Can you mail baked goods?
You can mail baked goods, and they are among the most common food parcels. Dense, dry items like shortbread, biscotti, and pound cake hold up best. They stay fresh and resist crushing.
Wrap each item or each small stack in plastic wrap or a sealed bag. Place the wrapped goods in a tin or small box. Put that inside a larger shipping box with at least an inch of cushioning on every side.
Avoid anything with cream cheese frosting, custard, or whipped cream. These spoil quickly and are the kind of easily decomposing food that Publication 52 treats as nonmailable when it cannot reach the destination in good condition. For picking the right box, see the guide to shipping box sizes and strength.
Can you ship frozen or refrigerated food in the mail?
Yes, but this is where mistakes happen. Frozen and cold food needs insulation, a coolant, and a fast delivery. A plain cardboard box with a loose ice pack will not hold temperature for long.
For USPS, the packaging must meet the strength and containment standards in DMM 601.1 through 6. Publication 52 also notes that a Live Animal and Perishable Handling Fee can apply to qualifying shipments. Notice 123 lists that fee at $15.00, so ask at the counter whether your parcel triggers it.
FedEx publishes more practical packing detail than USPS, and its steps are a useful model for any carrier. It calls for an insulated foam container with walls at least one and a half inches thick, placed inside an outer corrugated box. The foam should hold a watertight liner of 2 mil plastic to contain melting water.
How to pack a perishable box, step by step
- Chill or freeze the food completely before packing so the coolant does not have to do that work.
- Seal the food in leakproof bags or containers and cushion it so it cannot shift.
- Line an insulated foam container with a watertight bag and place the food inside.
- Add gel packs or double bagged wet ice around and on top of the food. FedEx notes gel packs hold 34 to 50 degrees Fahrenheit, and wet ice must be double bagged.
- Fill empty space with paper or foam, close the foam lid, and tape it shut.
- Place the foam container in a corrugated outer box, seal every seam, and mark it perishable.
What about dry ice?
Dry ice keeps food frozen far longer than gel packs, but it is regulated. Publication 52 section 349 permits up to 5 pounds of dry ice per mailpiece when the parcel travels by domestic air, and permits dry ice by domestic surface transportation with no pound limit stated in that section. It is prohibited in international mail and for APO, FPO, and DPO addresses.
Dry ice gives off carbon dioxide gas, so Publication 52 requires the mailpiece to be vented to allow that gas to escape, and a surface prepared package must never be routed by air. USPS places the packaging and marking details in Packaging Instruction 9A in Appendix C of Publication 52. Read that instruction before you pack, because your box must meet it exactly.
FedEx adds that dry ice needs hazardous materials documentation and cannot be dropped at retail locations. Those are FedEx rules and should not be assumed for USPS. If you do not want the paperwork, use gel packs and a faster service instead.
Common mistakes when you mail food
- Choosing a slow service to save a few dollars, then losing the whole parcel to spoilage.
- Skipping a liner, so melting ice soaks the outer box and weakens it.
- Mailing on a Thursday or Friday, which leaves the box in a facility over the weekend.
Another frequent slip is leaving food loose in the box. Shifting weight crushes soft items and breaks seals. Fill every gap so nothing moves when you shake the closed box.
Can you mail eggs and meat?
Eggs are mailable domestically when three conditions are met. Each egg is individually cushioned, the package can take normal postal handling, and expected temperature changes in postal custody are not likely to affect the eggs. In practice that rules out sending eggs in hot weather on a slow service.
Meat and meat products are mailable in domestic mail only when they follow USDA regulations. The package must also meet the strength and sealing standards in DMM 601.1 through 7, so leaks do not escape. If you use dry ice with meat, follow the dry ice conditions in Publication 52.
Meat cannot go in international mail at all under these rules. Do not plan on sending jerky or cured meats overseas just because they are shelf stable. That is a common surprise at the counter.
Which service is best for perishable food?
Speed matters more than price for food that can spoil. The fewer days in transit, the less coolant you need and the lower the risk. For most perishable parcels, Priority Mail Express is the fastest USPS option.
Notice 123 lists a Sunday and holiday delivery fee of $12.50 for Priority Mail Express. That matters for food, because a parcel sitting in a hot truck is the real danger. You can compare services with the Mail Class Selector before you buy.
If you do not need next day speed, Priority Mail is a lower cost step down. See how long Priority Mail takes to judge whether your food will make it.
Check the route with the Delivery Time Estimator for your ZIP codes. Enter the drop off day too, because a Thursday or Friday mailing can run into the weekend.
Timing rules that protect the food
- Ship early in the week, Monday through Wednesday, so the parcel does not wait in a facility over the weekend. FedEx gives this same advice for perishables.
- Protect the food for 24 hours beyond the promised delivery time, as FedEx recommends, in case of delay.
- Tell the recipient the day it is due, so it does not sit on a porch.
Can you mail food overnight?
Yes, Priority Mail Express offers overnight service on many routes, but it is not guaranteed everywhere. Delivery times depend on origin, destination, and the time of drop off. The Delivery Time Estimator shows what applies to your ZIP codes, and the Priority Mail Express page explains the guarantee terms.
Overnight shipping is worth it for frozen meat, seafood, and any food with a short safe window. For cookies and candy it is usually not needed. Save the money and spend it on better packing.
FedEx recommends overnight service for perishables, or packing to protect the food for 24 hours beyond the commitment. Using one of those two plans is a good rule for any carrier.
Can you ship food in the mail internationally?
International food shipping is much harder. USPS has a separate chapter section for international perishables, and the rules there are stricter than for domestic mail. Dry ice is prohibited internationally, and meat products cannot go in international mail under Publication 52.
Each destination country also sets its own import rules for food, and those can change. Many countries restrict meat, dairy, fresh produce, and even packaged snacks. A parcel that breaks the rules can be held, returned, or destroyed.
Before you send food abroad, check the destination country’s rules and list the contents accurately on the customs form. If you cannot confirm the food is allowed, do not send it. A card and a small gift that is not food may be the safer choice.
How do other carriers compare?
Each carrier writes its own perishables policy, and one carrier’s rules do not carry over to another. FedEx publishes a perishables guide with the packing, coolant, and timing advice described above. UPS also has its own perishable policies, so confirm them with UPS before you ship with that carrier.
Liquids add another layer, especially sauces, oils, and drinks. Our guide covers mailing liquids through USPS.
If you ship with UPS instead, read the UPS liquids rules separately. The two carriers do not write them the same way.
For the basic steps of booking and labeling any parcel, see how to ship a package with USPS. Label the box clearly, include the recipient’s phone number, and give them a heads up.
Bottom line: can you mail food?
Most food that survives a few days without refrigeration can go through the mail with sturdy packing. Fresh produce that rots, easily spoiled items, and anything meat related abroad should stay home. For cold items, use insulation, a coolant, and the fastest service you can afford.
