The gift basket looks harmless sitting on the counter. Inside sits a bottle of eau de parfum, two lacquers, a travel-size dry shampoo, and a bottle of Napa cabernet, and at least three of those items are regulated as hazardous material or barred outright. The staff at Newport Beach Mailboxes & More have this conversation constantly, usually with someone who has already sealed the box. Knowing the categories in advance saves a repack, a return trip, and occasionally a federal penalty.
Why is perfume treated as hazardous material?
Alcohol-based fragrance is a flammable liquid, and flammable liquids fall under the Hazardous Materials Regulations in 49 CFR, enforced by the Pipeline and Hazardous Materials Safety Administration. Perfume ships under UN1266, the identifier assigned to perfumery products containing solvents.
Classification has nothing to do with how dangerous the bottle feels in your hand. It depends on flash point, the lowest temperature at which a liquid gives off vapor that can ignite. Most fragrances, nail polishes, nail polish removers, hand sanitizers and aerosol hairsprays clear that bar comfortably.
Can you ship perfume, nail polish, or hairspray at all?
Yes, by ground, in small quantities, with the right markings. These products move domestically as Limited Quantity shipments, a regulatory category for small consumer-sized containers packed inside a compliant outer box and labeled with the black-and-white Limited Quantity diamond.
The ORM-D marking that used to cover this category was retired and is no longer valid for any mode, so an old box with an ORM-D stamp will be refused. USPS accepts qualifying flammable cosmetics only via ground service with surface transportation markings, and prohibits them in air service and in all international mail. UPS and FedEx apply similar ground-only restrictions at their retail counters, and moving these goods by air requires a dangerous goods contract, trained shippers, and a signed declaration.
Can you mail a vape or e-cigarette?
No. Electronic nicotine delivery systems cannot be shipped to consumers through USPS, UPS, FedEx or DHL.
The Preventing Online Sales of E-Cigarettes to Children Act, signed in December 2020, folded ENDS products into the PACT Act and led USPS to bar them from the mail outside narrow business and regulatory exceptions requiring advance approval. The major private carriers stopped accepting vaping products for consumer delivery during 2021 and have not reversed course. The restriction covers the device, the pods, the e-liquid and the accessories, and it applies whether the item is new, used, or being returned to a manufacturer.
What about lithium batteries shipped on their own?
Loose lithium batteries are ground-only, and they are prohibited in international mail through USPS entirely.
A battery installed in the device it powers is treated more leniently than the same battery packed separately. Standalone cells and spares must travel by surface transportation, each cell individually protected against short circuit with taped terminals or an insulating sleeve, packed so they cannot shift or contact one another. Consumer-scale limits sit at 20 watt-hours per cell and 100 watt-hours per battery, the same thresholds used for carry-on rules.
Damaged, defective or recalled lithium batteries are forbidden from transport in every mode. A swollen power bank or a recalled e-bike pack cannot be mailed back to the manufacturer, and disposal through a local household hazardous waste program is the only legitimate route.
Can you ship wine from California to relatives out of state?
Not as a private individual. USPS is statutorily barred from carrying alcoholic beverages of any kind, domestic or international. UPS and FedEx transport wine only for shippers holding a contract and the appropriate state licensing, meaning a winery, a licensed retailer, or a permitted fulfillment operation.
The compliant path runs through the seller. A California winery with direct-shipment permits can send to most states, subject to that state’s volume caps, and delivery requires an adult signature from someone 21 or older. Handing a personal bottle across a retail counter is not something any carrier will accept, and a box declared as something else is a separate problem.
What happens if you ship restricted goods without declaring them?
Undeclared hazardous material is a federal violation, not a policy infraction. PHMSA civil penalties exceed $100,000 per violation and are adjusted annually for inflation, with higher maximums where a release causes injury or death.
The practical consequences arrive sooner. Carriers screen for undeclared hazmat in their sorting hubs, and a flagged parcel is pulled and frequently destroyed rather than returned. No claim is payable on it, because the shipment violated the terms of carriage from the moment it was tendered. Repeat findings can close a shipping account.
What does Newport Beach Mailboxes & More check before accepting a package?
Contents first, then destination, then service level, because the same item can be perfectly legal by ground and prohibited by air on the same day.
International adds a second filter. Anything crossing a border moves by air at some point, so most flammable cosmetics that ship freely to Sacramento are simply not going to Vancouver or London. Country-specific bans on food, supplements, seeds and medications sit on top of that.
Bring the items in unpacked and unwrapped and the counter can sort the shippable from the unshippable before anything is boxed. Newport Beach Mailboxes & More can mark and pack a Limited Quantity ground shipment correctly, tell you plainly when an item has no legal path, and point you toward the one that does.
