How to Ship Fragile Items Without Breakage

None of the big three carriers sells a “fragile” service that handles your box more gently. The USPS price list has no fragile-handling option. UPS’s terms of service say it “does not provide special handling” for packages marked “Fragile” or “This End Up,” and FedEx says it can’t ensure that orientation arrows are followed. Whether a glass vase arrives in one piece depends almost entirely on how it was packed.

The carriers’ own packing rules are a good guide. FedEx recommends a box with room for 2 to 3 inches of cushioning on all six sides, and a box-in-box method for fragile items. USPS’s mailing standards require mailers to cushion fragile items and pack contents so they can’t shift. Packing also decides whether a damage claim gets paid. USPS won’t pay for an item packaged in a way that it “could not have reached its destination undamaged,” and FedEx caps the declared value of glassware, ceramics, artwork and antiques at $1,000.

This guide covers what each carrier requires, the box-in-box method, packing by item type, labels, and insurance.

Key Takeaways

Cushion and immobilize. FedEx calls for 2 to 3 inches of cushioning on all six sides. USPS requires that contents not shift and that loose fill overfill the box before you close it.
Double-box anything breakable. FedEx’s box-in-box method uses an outer box at least 6 inches longer, wider and deeper than the inner box, with 3 inches of cushioning between them.
“Fragile” labels don’t buy special handling at UPS or FedEx. USPS says to use a “Fragile” marking only on packages that really contain delicate items such as glass.
Know your coverage. USPS Ground Advantage, Priority Mail and Priority Mail Express include $100 of insurance, and UPS and FedEx include $100 of liability. FedEx limits glassware, artwork and antiques to $1,000 of declared value.

What the Carriers Require

USPS. The Domestic Mail Manual (DMM 601) says mailers “must package mailpieces to withstand normal transit and handling.” In practice that means:

Cushion fragile items.
Pack contents so they don’t shift.
Brace heavy items.
Use loose-fill cushioning that “must overfill the container before closure.”
When there’s more than one item, cushion items from each other as well as from the outside of the box, and don’t pack dense, heavy items with fragile ones unless they’re carefully separated.

Corrugated fiberboard boxes can carry up to 70 lb, while plain paperboard boxes are limited to 10 lb. Used boxes are acceptable if they’re rigid and all their flaps are intact. Tape should be at least 2 inches wide, and cellophane and masking tape aren’t acceptable. USPS’s consumer guide adds a reminder that your package will share space with others “that could weigh as much as 70 lbs.”

FedEx. FedEx’s packing page asks for 2 to 3 inches of cushioning on all six sides and tape at least 3 inches wide, applied in the H pattern (across the center seam and both edge seams). You can reuse a box if it hasn’t been crushed, torn or punctured. FedEx’s General Packaging Guidelines add these rules:

Use double-wall boxes for heavier items.
Pack chipboard gift or shoe boxes inside a corrugated outer box.
Don’t seal a package with cellophane tape, duct tape, masking tape, string or rope.
Never wrap the outside of the box in stretch wrap or bubble wrap.

UPS. UPS’s Tariff/Terms and Conditions of Service (effective April 17, 2026) put packing on the shipper. It says the shipper must make sure “contents are adequately and securely packed,” and that even UPS-provided packaging “is not a guarantee that an item is sufficiently packaged for transportation.”

Choosing Cushioning Materials

The FedEx and USPS guidance points to two jobs for cushioning: wrapping the item, and filling the empty space so nothing moves.

Wrapping: air-cellular cushioning (bubble wrap) or foam goes directly around the item. FedEx’s box-in-box method calls for at least 2 inches of it around each item, and its single-box method calls for at least 3 inches.
Void fill: crumpled paper, loose-fill peanuts or air pillows go around the wrapped item. They protect only when packed tightly enough that the item can’t settle toward a wall of the box, which is why USPS requires loose fill to overfill the container before it’s closed.
Dividers and inserts: corrugated dividers or molded inserts keep multiple items from touching. USPS requires multiple items to be cushioned from each other, not just from the outside of the box.

Once the box is sealed, give it a gentle shake. If you can feel or hear anything move, open it and add cushioning.

The Box-in-Box (Double-Box) Method

FedEx’s General Packaging Guidelines describe the method step by step:

Wrap each item individually in at least 2 inches of air-cellular cushioning or foam, so it fits snugly inside a corrugated inner box.
Fill any gaps so the item can’t move, then close the inner box with H-pattern taping.
Choose an outer box at least 6 inches longer, wider and deeper than the inner box.
Surround the inner box with 3 inches of cushioning on the top, bottom and all sides, either by wrapping it or with loose fill.
Fill any remaining voids and seal the outer box with the H method.

The outer box and the layer between the boxes absorb the bumps, and the inner box keeps the item centered and away from the walls. For anything breakable, valuable or irreplaceable, it’s worth the extra box.

Packing Techniques by Item Type

Glass, Ceramics and Dishware

Wrap each piece separately and fill hollow items such as mugs and vases with paper. Give handles, spouts, stems and other parts that stick out extra padding. Keep pieces from touching, using dividers if you’re shipping a set. Don’t let a heavy item share a box with fragile ones unless they’re well separated, which USPS’s cushioning standard specifically warns against. Then double-box. Remember that FedEx’s Service Guide treats “glassware, including … ceramics, porcelains, china, crystal, glass, framed glass” as items with a maximum declared value of $1,000.

Electronics

Original manufacturer packaging, with its fitted inserts, is usually the best option. Without it, wrap the device and double-box it. Use anti-static bags for bare circuit boards or components. Batteries need attention too. USPS says pre-owned, damaged or defective electronic devices that contain or are packed with lithium batteries must travel by ground and be marked “Restricted Electronic Device” and “Surface Transportation Only.” Check each carrier’s hazardous-materials rules before you ship. FedEx’s $1,000 declared-value cap also applies to plasma screens.

Framed Art, Mirrors and Photos

FedEx advises applying masking tape in a criss-cross pattern on the glass so it doesn’t splinter if it breaks. Protect the corners, wrap the piece, and use a telescoping picture or mirror box so it fits snugly. FedEx Office sells framed-art boxes and offers professional packing. For unframed photos and posterboard, FedEx suggests taping them to a rigid backing or sandwiching them between corrugated pads. FedEx limits artwork, including paintings, prints and sculpture, to $1,000 of declared value.

Liquids, Bottles and Jars

USPS has detailed rules here (DMM 601.3.4):

Mark the outer box to show it contains liquid, and add orientation arrows.
Close containers with screw-on caps of at least one and a half turns.
Triple-package breakable containers holding more than 4 fluid ounces. That means absorbent cushioning that can soak up all the liquid, then a sealed, leakproof secondary container such as a plastic bag, then a strong outer box.

FedEx says to pack bottles upright, with inner packaging that can contain leaks.

Alcohol has its own rules. USPS says beer, wine and liquor “may not be sent through the mail, except in limited circumstances,” and a reused box with alcohol logos must have them removed. FedEx says individuals “cannot ship alcohol via FedEx.” Only licensed businesses enrolled in its alcohol shipping program can. UPS accepts alcohol only under a contract with licensed shippers, and every package requires an adult signature.

Musical Instruments

FedEx suggests loosening the string tension to take stress off the neck, then packing the instrument in a strong box with cushioning. FedEx Office sells a guitar box. Under FedEx’s Service Guide, guitars and other instruments more than 20 years old, and customized or personalized instruments, are capped at $1,000 of declared value.

Labels and Markings: What They Do and Don’t Do

A “Fragile” sticker can make sense, but don’t count on it. USPS’s standards say handling markings like “Fragile” should go “only to packages containing delicate items such as glass and electrical appliances.” UPS’s terms say it gives no special handling for “Fragile” or orientation markings, and FedEx says it “can’t ensure compliance” with “Up” arrows. FedEx does note that placing the shipping label on the box’s largest surface “increases your chance for the preferred orientation.”

Other labeling steps that help:

Remove or black out old labels and barcodes on reused boxes. USPS and FedEx both ask for this.
Put an address card inside. FedEx recommends enclosing a copy of the shipper’s and recipient’s addresses and phone numbers in case the outer label is damaged.
Don’t advertise the contents of valuable items. UPS’s terms say shipments of high-value goods such as computers and phones must not have labels or markings that reveal what’s inside.

Insurance, Declared Value and Claims

USPS. Ground Advantage, Priority Mail and Priority Mail Express include up to $100 of insurance, and you can buy coverage up to $5,000. As of October 2026, Notice 123 lists insurance at $4.50 for coverage up to $200 and $7.55 for up to $500, plus $1.50 per $100 above $600.

FedEx. The first $100 of value is included in the shipping rate, and you can pay to declare more. The 2026 Service Guide (updated Sept. 11, 2026) limits shipments containing artwork, antiques, glassware and the other fragile categories above to $1,000 of declared value.

UPS. UPS liability is $100 per package unless you declare a higher value and pay for it.

Packing also matters when you file a claim. DMM 609 lists situations where USPS won’t pay:

Damage from abrasion or scraping to items “not properly wrapped for protection.”
Damage from shock “without evidence of damage to the mailing container.”
Cases where the “fragile nature of article prevented its safe carriage in the mail, regardless of packaging.”
Items packaged so they could not have arrived undamaged.

USPS also requires the recipient to keep the box, all the packaging and the damaged item, and to show them to USPS if it asks. For step-by-step help, see how to file a shipping claim and how to file a USPS insurance claim.

Professional Packing and Testing

If you’re not confident packing something valuable, a store can do it for you. FedEx’s guidelines suggest you “let the pros do the packing” at FedEx Office. The UPS Store’s franchise locations advertise a Pack & Ship Guarantee for items their staff pack. Terms vary by location, and at least some limit reimbursement to $100 unless you buy declared value, so ask before you pay. Businesses with a FedEx account can also have the FedEx Packaging Lab test a package design, which FedEx says is free for account holders.

Next Steps

Gather a sturdy corrugated box, cushioning and 2- to 3-inch tape before you start. Our shipping supplies guide compares the basics.
Double-box anything breakable, and do the shake test before sealing the outer box.
Insure or declare the item’s value if it’s worth more than $100, and photograph it and the packing before you seal the box.
