Mailability: hazardous, restricted and perishable items

USPS refuses anything that may kill or injure someone or damage the mail, and accepts some hazardous, restricted and perishable items only under the conditions of its rulebook, Publication 52. Permitted hazardous materials carry warning labels, the proper shipping name and the UN number on the address side, and hazardous materials codes in the barcode.

Questions

How do I ship a laptop with a lithium battery through USPS?

A laptop with its lithium-ion battery installed can go by air or ground, if the battery is rated at 100 watt-hours or less. A used laptop goes by ground only, marked Restricted Electronic Device and Surface Transportation Only. A piece holds no more than eight cells or two batteries, and lithium batteries gives the other limits.

Can you send live animals in the mail?

Only some live animals are mailable, each under its own conditions, such as bees and day-old poultry. Warm-blooded pets such as cats, kittens, dogs and puppies are not mailable. Adult birds travel only by Priority Mail Express, and perishable matter lists every kind that is mailable.

Why does USPS ask about lithium batteries, and does it charge extra?

USPS retail clerks must ask whether a package holds anything potentially hazardous, such as lithium batteries, to set the limits, labels and packaging it needs. As of July 12, 2026, Priority Mail Express and Priority Mail parcels with hazardous materials, lithium batteries included, pay a $7.50 HazMat Handling Fee. USPS Ground Advantage and Parcel Select parcels pay $0.00, as marking and codes explains.

How do I mail cremated remains through USPS, and how much does it cost?

Within the United States, cremated remains go only by Priority Mail Express, in a strong, sealed, sift-proof receptacle inside USPS's own cremated remains box, BOX-CRE. Priority Mail Express postage goes by weight and zone: as of October 4, 2026, a retail piece up to 0.5 pound costs from $37.05. Additional insurance and Return Receipt, the only extra services allowed, are charged on top of the postage.

What is considered hazardous material for shipping?

A hazardous material is any article or substance the U.S. Department of Transportation designates as able to pose unreasonable risks to health, safety or property in transportation. Each one belongs to one of nine hazard classes, such as explosives, gases or flammable liquids. Each is mailable, mailable with restrictions, or prohibited, as hazardous materials explains.

Does USPS ship lithium batteries internationally?

Only lithium batteries installed in the equipment they operate may go abroad, at most four cells or two batteries a shipment. The piece must not show any mark or label that says it holds lithium batteries. Used, damaged, defective or recalled batteries, and used or damaged devices that hold them, never go abroad.

Can you mail dry ice with USPS?

Yes, within the United States: a piece may hold up to 5 pounds of dry ice by air, and more by surface. The package must be vented and marked with what the dry ice cools, the dry ice's net weight and Dry Ice, UN1845, as dry ice explains. International mail takes no dry ice.

Can you mail alcohol with USPS?

No: USPS does not accept intoxicating liquors, taxable beverages with 0.5 percent or more alcohol by weight, even by prescription or as a collector's item. Cooking wine, mouthwash and other alcohol products are mailable if they meet IRS and FDA rules and are not taxable beverages, poisonous or flammable. Federal and state agency employees may mail liquor to each other for official use, as restricted matter explains. International mail prohibits intoxicating liquor too, as it does all matter that is nonmailable at home.

How it fits together

Federal law makes all matter that is dangerous to life, health or property nonmailable, and USPS's mailability rules start from that premise. Publication 52, Hazardous, Restricted, and Perishable Mail, sets the conditions under which some of that matter is still accepted. It sorts the matter into three kinds: hazardous materials, restricted matter and perishable matter. Each kind holds items that are mailable, mailable with restrictions, or prohibited.

Hazardous materials fall into nine hazard classes, and USPS generally takes only retail-sized consumer quantities of them. Their rules depend on how a piece travels: Priority Mail Express and Priority Mail meet air rules, and USPS Ground Advantage meets surface rules. Lithium batteries and dry ice are hazardous materials with limits of their own. A permitted piece carries its labels on the address side and hazardous materials codes in its barcode, which package labels also covers.

Restricted matter is matter that federal law limits, such as liquor, firearms, sharp objects and tobacco. Perishable matter, such as live animals, food and plants, can spoil in the mail and goes at the mailer's own risk. A handling fee, one of the extra services, also applies to live animals and perishable items.

International mail is stricter: almost all dangerous goods are prohibited, and matter nonmailable at home is prohibited abroad too. When mailability is uncertain, the mailer can ask the PCSC, USPS's Pricing and Classification Service Center, for a ruling. Product Classification, an office at USPS Headquarters, also takes these requests and decides appeals of the PCSC's rulings.

Hazardous materials

A hazardous material is an article or substance that the U.S. Department of Transportation, DOT, designates as able to pose unreasonable risks in transportation. In international commerce it is called dangerous goods. DOT regulates its carriage under 49 CFR, and USPS rules follow 49 CFR with more limits and prohibitions of their own.

DOT assigns every hazardous material to one of nine hazard classes:

  • Class 1, explosives.
  • Class 2, gases.
  • Class 3, flammable and combustible liquids.
  • Class 4, flammable solids.
  • Class 5, oxidizing substances and organic peroxides.
  • Class 6, toxic substances and infectious substances.
  • Class 7, radioactive materials.
  • Class 8, corrosives.
  • Class 9, miscellaneous hazardous materials, such as lithium batteries and dry ice.

Domestic mail generally takes only materials DOT allows as a Limited Quantity, sold in retail form and meant for personal care or household use. Such a material is a consumer commodity. The hazardous materials table in Appendix A shows whether each material is mailable by air and by surface, found by its proper shipping name. To get a mailability decision, the mailer gives the Post Office a Safety Data Sheet and details about the material.

The mode of transportation decides the rules. Anything sent as Priority Mail Express or Priority Mail must meet the air rules, however it actually travels. These are always prohibited by air:

  • Explosives.
  • Flammable gases, liquids and solids.
  • Radioactive materials.
  • Lithium batteries without their equipment.

Four provisions let small amounts travel with fewer DOT requirements:

  • Limited Quantity surface material presents a limited hazard by its form, quantity and packaging, and never goes by Priority Mail Express or Priority Mail.
  • ID8000 material is a consumer commodity of Class 2, 3 or Division 6.1 that may go by air.
  • An excepted quantity may go by domestic air or surface, at most 30 g or 30 ml in each inner packaging.
  • A small quantity may go only by domestic highway and rail.

An aerosol is a nonrefillable metal can of gas under pressure that sprays out a liquid, paste or powder. The hazardous materials table lists flammable aerosols as Division 2.1, flammable gases, and nonflammable ones as Division 2.2. By domestic air, flammable gases are prohibited, and nonflammable gases generally go when they qualify as ID8000 material. By domestic surface, both generally go as Limited Quantity material, within quantity and packaging limits. International mail takes no gases.

Aerosol paint that counts as a flammable compressed gas goes by surface only, as Limited Quantity material. Flammable liquids, such as rubbing alcohol, are prohibited by air. A liquid's flashpoint is the lowest temperature at which it gives off enough vapor to form an ignitable mixture with air. By surface, flammable liquids with a flashpoint at or below 20° F (-7° C) are prohibited too. The others go by surface only as Limited Quantity material that meets Exhibit 343.21.

Some hazardous materials need USPS approval before the first mailing, and the product page explains each:

  • Toy propellant devices, a mailable explosive, by surface once Product Classification approves them.
  • Safety fuses, the only other mailable explosive, by surface under the same approval.
  • Lighters, with an approval letter from the PCSC director.
  • Ethanol-based flammable liquids and solids, by domestic air with prior written authorization.
  • Sharps and regulated medical waste, in container systems whose vendors USPS authorizes.

Category B infectious substances go within the United States only for medical or veterinary use, research, or public health laboratory certification. They travel in triple packaging, by Priority Mail or Priority Mail Express. To go abroad, they also need written approval from the director of Product Classification.

Must
Mailers must identify whether a shipment contains hazardous materials when generating the label, including Postal Service-generated labels (e.g., from USPS Application Programming Interfaces (API), Click-N-Ship, or Merchant Returns Application).

A mailer must say whether a shipment holds hazardous materials when making its label, including labels made with USPS's own tools.

hazard class

“Hazard class means the category to which a hazardous material is assigned under the definitions set by DOT in 49 CFR.”

Limited Quantity

“Limited Quantity is the maximum amount of a specific hazardous material that is exempted from the labeling or packaging requirements in 49 CFR.”

consumer commodity

“A hazardous material that is packaged and distributed in a quantity and form intended or suitable for retail sale and designed for consumption by individuals for their personal care or household use purposes. This term can include certain drugs or medicines. Not all hazardous material permitted to be mailed as a limited quantity can qualify as a consumer commodity.”

ID8000

“Certain hazardous materials in Classes 2 and 3 and Division 6.1 may qualify as consumer commodity subject to the applicable 49 CFR requirements and are reclassed as ID8000 when authorized to be carried on passenger aircraft.”

excepted quantity

“An excepted quantity refers to a defined amount of a specific hazardous material that is eligible for transport aboard passenger aircraft and is exempt from most DOT requirements (e.g., packaging, marking, labeling) under 49 CFR § 173.4a.”

small quantity

“Small quantity is the maximum amount of a specific hazardous material that is not subject to any requirements other than those in 49 CFR § 173.4.”

Safety Data Sheet

Also called SDS, MSDS, Material Safety Data Sheet

“Safety Data Sheet (SDS) is a document that details the physical characteristics and health hazards of a chemical or hazardous product.”

Hazardous Materials

Also called HAZMAT, Dangerous goods

“Any article or substance designated by the U.S. Department of Transportation (DOT) as being capable of posing an unreasonable risk to health, safety, and property during transportation. Not all hazardous materials are mailable, and those that are mailable must be prepared, documented, and marked according to specific requirements.”

Lithium batteries and dry ice

Lithium batteries and dry ice are Class 9 hazardous materials, mailable within limits that depend on how a piece travels. A lithium-ion battery is rechargeable, as in phones and laptops. A lithium metal battery is not, and it often powers cameras and flashlights.

Every cell or battery must meet the UN Manual of Tests and Criteria, and the outer packaging must be rigid. Batteries go by air only in or with the equipment they run:

BatteryIn or with its equipmentWithout equipment
Lithium-ionAir or surface; each cell up to 20 Wh, each battery up to 100 WhSurface only, in its sealed packaging, in a piece of up to 5 pounds
Lithium metalAir or surface; each cell up to 1.0 gram of lithium, each battery up to 2.0 gramsSurface only, in its sealed packaging, in a piece of up to 5 pounds

With equipment, a piece holds no more than eight cells or two batteries. Very small batteries, up to 2.7 Wh or 0.3 grams of lithium, have no count limit in a piece of up to 5.5 pounds. Used, damaged or defective devices go by surface only, marked Restricted Electronic Device and Surface Transportation Only. Damaged, defective or recalled batteries are prohibited, unless the director of Product Classification approves them.

The DOT lithium battery mark goes flat on the address side, never folded over two sides. It shows the UN number for the battery and how it is packed:

Proper shipping nameUN number
Lithium-ion batteryUN3480
Lithium-ion battery contained in or packed with equipmentUN3481
Lithium metal batteryUN3090
Lithium metal battery contained in or packed with equipmentUN3091

A piece with no more than four cells or two batteries installed in the equipment they run needs no mark. A piece of loose batteries also says that it goes by surface only and is forbidden aboard passenger aircraft.

Dry ice is solid carbon dioxide, used mainly to keep other items cool, such as medical specimens or foods. As it turns to gas it can displace oxygen, and in a closed container its pressure can make the container burst. A package with dry ice must be vented, and a piece sent by air holds at most 5 pounds. Dry ice is prohibited in international mail.

Every piece with dry ice is marked on the address side with what the dry ice cools and the dry ice's net weight. By air, the piece carries a Class 9 warning label and the mark Dry Ice, UN1845. It also needs a Shipper's Declaration for Dangerous Goods, the shipping paper for air, fixed to its outside in triplicate. By surface, the piece is marked Surface Only and Dry Ice, UN1845, needs no declaration or Class 9 label, and may hold more than 5 pounds.

lithium battery

“Lithium battery: A unit composed of one or more lithium cells which are electrically connected together by a permanent means, including case, terminals, and markings.”

lithium-ion battery

Also called Lithium-Ion Cell or Battery, secondary lithium cells or batteries

“Lithium-Ion Cell or Battery: A rechargeable electrochemical cell or battery in which the positive and negative electrodes are both lithium compounds constructed with no metallic lithium in either electrode.”

lithium metal battery

Also called Lithium Metal Cell or Battery, primary lithium cells or batteries

“Lithium Metal Cell or Battery: A non-rechargeable electrochemical cell or battery utilizing lithium metal or lithium alloys as the anode.”

dry ice

Also called carbon dioxide solid

“Dry ice (carbon dioxide solid) is produced by expanding liquid carbon dioxide to vapor and compacting the material into blocks.”

Marking and codes

A package of hazardous materials must show the DOT warning labels and markings that 49 CFR 172.407 through 172.446 set out. Only the warning labels in Exhibits 325.4a, 325.4b and 325.5 of Publication 52 are permitted in USPS networks. The sizes and colors of the labels those exhibits show are for reference only, and they don't meet DOT's standards unless an exhibit notes otherwise.

Every hazardous materials label and marking goes on the address side, with the proper shipping name and the UN number. Labels may go on an adjacent side when space runs out, but never on the bottom. A UN number is the four-digit number the United Nations assigns to a hazardous material. DOT warning labels are diamonds at least 100 mm on each side.

A Limited Quantity mark is a diamond with a black top and bottom. For air it has a black Y in the center, and the piece also shows the proper shipping name and identification number. For surface, the mark alone is enough.

Most mailable hazardous materials sent by air need shipping documentation, and some sent by surface need it too. For air it is a Shipper's Declaration for Dangerous Goods, and for surface a shipping paper. The mailer signs it in triplicate and fixes it to the outside of the piece in an envelope that opens easily.

In the barcode, a hazardous materials package carries a service type code of its own, which names the product and marks the contents as hazardous. Every such package also carries an extra service code for hazardous material, and USPS strongly recommends a second code for its category. The label shows an H service icon in its upper left corner. Pieces to military addresses or to U.S. Possessions, Territories, and Freely Associated States use no hazardous materials service type code and no H icon, and they follow international rules.

Must
Mailers tendering packages that contain hazardous materials to the Postal Service must use Extra Service Code (ESC) 857.

Every package that holds hazardous materials must carry extra service code 857.

The extra service code for any hazardous material, then one code for each category.

As of July 12, 2026, a Priority Mail Express or Priority Mail parcel that holds hazardous materials pays a $7.50 HazMat Handling Fee. A USPS Ground Advantage or Parcel Select parcel that holds them pays $0.00. A commercial parcel whose hazardous materials USPS detects but the mailer did not declare or label pays a $50.00 HazMat Noncompliance Fee.

Mailing a hazardous material.

  1. The mailer identifies the material's hazardous properties, such as flashpoint and toxicity.
  2. The mailer finds its proper shipping name in Appendix A to learn its mailability.
  3. The mailer packs it by the Packaging Instruction in Appendix C for its mode.
  4. The mailer puts every required label and mark on the address side.
  5. The mailer declares the hazardous material when making the label.
  6. The mailer presents hazardous materials pieces apart from other mail, in containers marked HAZMAT.

Hazmat Extra Service Codes

Also called content-specific ESC, category-specific ESCs

“The Postal Service has also defined Extra Service Codes (ESCs) to identify the category of hazardous material that is associated with specific quantity restrictions, packaging and markings requirements, and for some ESCs, restrictions in air transportation.”

proper shipping name

“Proper shipping name is the name of a hazardous material that must be used to identify a substance or article in the shipping documents and on the packaging, as required.”

Shipper's Declaration for Dangerous Goods

“Shipping papers are referred to as a Shipper's Declaration for Dangerous Goods when being offered for air transportation according to the Dangerous Goods Regulations of the International Air Transport Association (IATA).”

Service Type Code

Also called STC

“Service Type Codes are designators used to represent USPS classes of mail in conjunction with the type of Extra Service(s) being requested.”

UN Number

“The United Nations (UN) four-digit identification number assigned to a hazardous material that is recognized for use in international and domestic commerce and transportation.”

shipping paper

“Domestically, a shipping paper means a shipping order, bill of lading, waybill, or manifest, per 49 CFR § 171.8, which identifies hazardous materials being offered for surface transportation.”

Restricted matter

Restricted matter is matter whose mailing federal law generally restricts. The mailer must meet USPS rules and every federal, state and local law on shipping it. A doubtful item can go to the local postmaster for a ruling.

ItemIn domestic mail
Intoxicating liquorsNonmailable, even by prescription or as a collector's item; exempt only between federal or state agency employees for official use
HandgunsNonmailable, except between licensed manufacturers, dealers and importers, or to listed officials for official duties after an affidavit
Unloaded rifles and shotgunsMailable under federal, state and local law
Switchblade knivesMailable only to government supply or procurement officials, and by makers and dealers to them
Other knives and sharp instrumentsMailable in a strong container, cushioned so edges cannot cut through
Cigarettes, smokeless tobacco and electronic nicotine delivery systemsGenerally nonmailable, unless an exception applies
Cremated remainsPriority Mail Express only, in USPS's BOX-CRE box
Nonhazardous liquids and powdersMailable when packed leakproof or sift-proof
Matter with an obnoxious odorNonmailable

Regulated firearms travel with tracking and a signature at delivery, unless they go between licensed dealers, manufacturers or importers. USPS may require the mailer to open the package, or certify in writing that the weapon is unloaded and not concealable. Licensed makers, dealers and importers who mail handguns file PS Form 1508, Statement by Shipper of Firearms, with the postmaster. Postmasters give no opinion on whether a firearm shipment is legal, and they refer mailers to ATF. Small arms ammunition is prohibited from mailing.

A package with a mailable firearm must carry no mark on its outside wrapper or container that says what it holds.

Cremated remains in any form, such as ashes, keepsakes or jewelry, go within the United States only by Priority Mail Express. Abroad, they go only by Priority Mail Express International, and only where the destination country permits them. Every cremated remains mailing uses USPS's own BOX-CRE box.

The receptacle that holds the remains must be strong, durable and sealed so that it is sift-proof. Abroad, it must be a funeral urn, sealed and sift-proof. The mailer seals the receptacle in a plastic bag, places it in the box, and pads the bottom, sides and top so nothing moves. USPS recommends a slip on the bag with both addresses and the words Cremated Remains, in case the label comes off.

Cigarettes, smokeless tobacco and electronic nicotine delivery systems have narrow exceptions, for example between licensed businesses. Drug mail-back programs let authorized DEA registrants receive unused drugs for disposal.

Publication 52 covers articles and substances, and the Domestic Mail Manual covers nonmailable written, printed and graphic matter. That matter includes certain solicitations, lottery matter and some advertising. The addressee of a pandering advertisement can ask USPS for a prohibitory order, which directs the sender to make no further mailing to that addressee. The PCSC handles these orders.

intoxicating liquors

Also called alcoholic beverages

“Intoxicating liquors are beverages with an alcohol content of 0.5 percent or more by weight and are taxable per Chapter 51 of the United States (U.S.) Internal Revenue Service (IRS) Code.”

firearm

“Firearm: Any device, including a starter gun, which will, or is designed to, or may readily be converted to, expel a projectile by the action of an explosive; the frame or receiver of any such weapon; any firearm muffler or firearm silencer; or any destructive device; but the term shall not include antique firearms (except antique firearms meeting the description of a handgun or of a firearm capable of being concealed on a person).”

handgun

“Handgun (Including Pistols and Revolvers): A firearm with a short stock designed to be held and fired by the use of a single hand and subject to 431.1, or a combination of parts from which a handgun can be assembled.”

sharp instruments

“Sharp instruments include all sharp-pointed or sharp-edged implements, such as knives, tools, ice picks, razor blades, stilettos, or similar devices.”

switchblade knife

“A switchblade knife features a blade that opens automatically by hand pressure applied to a button or other device on the handle, or through inertia, gravity, or both.”

prohibitory order

“A USPS order requested by the addressee of a pandering advertisement that directs the sender to make no further mailing to that addressee.”

nonmailable written, printed, and graphic matter

“Matter that would be otherwise mailable that includes certain solicitations, lottery and certain advertising matter, and matter using any fictitious name, title, or address in conducting any scheme or device in violation of law. The solicitations may be either in guise of bills, invoices, or statements of account, or they may deceptively imply federal connection, approval, or endorsement.”

restricted matter

“Any item on which certain mailing restrictions have been imposed for legal reasons other than risk of harm to persons or property involved in moving the mail and that require specific endorsements and markings. Examples include intoxicating liquors, abortive or contraceptive devices, odd-shaped items in envelopes, motor vehicle master keys, locksmithing devices as well as odor-producing materials, certain liquids and powders, battery-powered devices, and certain tobacco products.”

Perishable matter and live animals

Perishable matter is anything that can deteriorate in the mail and so lose value, create a health hazard, or cause an odor or nuisance. It goes at the mailer's own risk, packaged as required and deliverable before it spoils. The Live Animal and Perishable Handling Fee applies to live animals and perishable items, such as fruit and meat. It applies to Priority Mail Express, Priority Mail and USPS Ground Advantage.

These live animals are mailable, each under its own conditions:

  • Honeybees, by surface only, and queen honeybees, by air or surface.
  • Day-old poultry, no more than 24 hours old, in the hatchery's original, unopened box.
  • Adult birds, by Priority Mail Express only, in a container Product Classification approved.
  • Scorpions, only for medical research or the manufacture of antivenin.
  • Small, harmless cold-blooded animals, except snakes, turtles and turtle eggs.

Other warm-blooded animals are not mailable. Snakes, turtles and poisonous reptiles are not mailable either, and neither are poisonous insects or any spider. A live animal container is at least 275-pound test, double-wall fiberboard, and USPS packaging such as Flat Rate boxes cannot be used.

Must
Each mailpiece must display a complete return address and be marked on the address side with a description of the contents (e.g., "Live Animals," "Live Honeybees").

A piece with live animals must show a complete return address and must name its contents on the address side.

Fresh fruits and vegetables are mailable only when dry, and other foods that spoil before they arrive are not mailable. Meat goes only under U.S. Department of Agriculture rules, and eggs only when each one is cushioned. Dry ice that keeps meat cold follows the dry ice rules. Plants are mailable within the United States, but a quarantine can make a plant nonmailable from its area.

International mail

Almost all dangerous goods are prohibited in international mail. Only biological substances, limited amounts of radioactive material, certain magnetized materials and lithium batteries installed in equipment can go, under specific circumstances. Countries add their own limits, so the mailer checks the destination's Individual Country Listing in the International Mail Manual.

Shipments to U.S. Possessions, Territories, and Freely Associated States follow the international rules for dangerous goods, because they are outside the U.S. customs territory. International dangerous goods shipments carry extra service code 857 and the code for their category.

Matter that is nonmailable at home, such as intoxicating liquor, is also prohibited abroad. The domestic firearms rules apply abroad too, and many firearms are prohibited. Most live or dead animals are nonmailable in international mail.

What goes wrong

  • A reused box that still shows hazardous materials or alcohol markings is treated as holding those contents. USPS employees cannot remove the marks, even when the mailer asks.
  • Surface labels on Priority Mail Express or Priority Mail, used to keep a piece off aircraft, are prohibited.
  • Combining several extra services on a package of hazardous materials, such as Signature Confirmation with insurance, is prohibited.
  • A package of hazardous materials that misses any compliance element can draw the Hazmat Quality fee, as package payment explains.
  • Live animals marked If Undeliverable, Abandon are not eligible for mailing.
  • Live animals that cannot be delivered or returned within the delivery period marked on the package are disposed of.
  • Anyone who knowingly mails dangerous matter may owe a civil penalty per violation, cleanup costs and criminal penalties, as the product page explains.
