Many online sellers, particularly those starting out, may not be fully aware of the rules each carrier has when it comes to shipping liquids. Since shipping rates and guidelines are updated each year, things can become difficult to get right. On top of that, Google seems to think that the only liquid people want to ship is alcohol, so that dominates the search results (by the way, we cover that in this support article). Plus, shipping food with USPS comes with its own set of guidelines that are completely different from liquids.
To help merchants who ship liquids often—vendors like CBD oil, essential oils, makeup and beauty supplies, and more—we did some digging ourselves to help you understand the rules to follow when shipping liquids via USPS, FedEx, and UPS.

Rules for FedEx
FedEx does a pretty good job of laying out some of their guidelines for shipping liquids in a step-by-step fashion, with a helpful graphic below. We’ve pulled some of the most important information from the pdf to feature it in one place for you.
Primary watertight inner receptacle
Use watertight containers for liquid specimens with a positive closure such as a screw-on, snap-on, or push-on lid, taped for an additional seal. If you place multiple fragile primary receptacles in a single secondary receptacle, they must be individually wrapped or separated to prevent contact between them.
Absorbent material
Place absorbent material between the primary and secondary receptacles, using enough material to absorb the entire contents of all primary receptacles. Suggested absorbent materials include cellulose wadding, cotton balls, superabsorbent packets, and paper towels.
Secondary watertight inner receptacle
Use a watertight sealed plastic bag, plastic canister, or screw-cap can.
Sturdy outer packaging
Use rigid outer packaging constructed of corrugated fiberboard, wood, metal, plastic, or other equally strong material, including cylinders made of such materials and appropriately sized for the contents. Chipboard or paperboard boxes, paper envelopes, and plastic bags are unacceptable outer packaging. The completed packaging must be of good quality, strong enough to withstand the normal rigors of transportation without loss of contents as a result of vibration, changes in temperature, humidity, or pressure
Note that there are specific labeling and possibly packaging guidelines if you are shipping human/biological specimens using FedEx. FedEx also prohibits containers of liquids with a volume exceeding 8 gallons (32 liters) or 70 lbs. in weight for FedEx Ground and SameDay City.

Rules for USPS
Nonflammable liquids and nonhazardous liquids can be sent via USPS, if sealed inside a waterproof container. A recently proposed rule change states that mailers must mark the outer container of a mailpiece containing liquid to indicate the nature of the contents, and include orientation arrows. This is regardless of whether the package is deemed “breakable” by the shipper.
If you are shipping liquids in containers greater than 4 oz, you are required to triple pack these containers. This means you need to pad around the original container(s), then surround the original packaging with another sealed, leak-proof container which includes absorbent materials, then have that packing in the rigid packaging noted far above, such as a Priority Mail box, USPS Flat Rate box, or Regional Rate box.
Liquids are also perfect candidates for cubic pricing like ShippingEasy’s Flat Rate Green. This applies to smaller, heavier packages (2 – 20 lbs.). A ShippingEasy customer who sells 6 and 12-packs of vitamin-infused water cut 40% off their shipping budget by switching from FedEx to using Flat Rate Green.
If you ship larger packs of liquid, say, 6 packs or 12 packs, cubic pricing can make your 18 lb. case the same price as a 2 lb. case and save an almost unbelievable amount of money per package.
— Michael Trotzuk, ShippingEasy shipping expert
Remember too, if your package weighs less than 16 oz, you can ship it using First Class Package Service, which allows you to use your own box and is the cheapest method for shipping under 1 lb.

If you’re shipping liquids in primary containers with less than 4 oz of liquids, you recently dodged a bullet. The USPS was considering enforcing the triple packing rule across the board, meaning companies like essential oils, CBD oils, and beauty supplies would have had to invest in more padding and packaging, driving up the cost of shipping these products. For now, USPS has decided to continue monitoring these items and will not make the rule change at this time.

UPS doesn’t do a great job of elucidating their specific rules to shipping liquids. It can be inferred from some short mentions on their website that their rules resemble those of FedEx pretty closely. If there’s any uncertainty, it’s always best to reach out to your UPS rep for clarity and ensure your packages arrive as they should.
