A box that arrives crushed doesn’t just cost you a replacement item — it costs you a customer, and often a denied claim on top of it. Most transit damage traces back to a handful of fixable packaging habits, and most claim denials trace back to missing documentation, not bad luck.
This guide covers the packaging fixes that actually cut down on damage, plus the exact evidence and timelines you need to get UPS, FedEx, or USPS to pay out when something still goes wrong.
Quick Answer
Cut transit damage by eliminating movement inside the box — right-sized cartons, snug void fill, and cushioning matched to the product’s fragility — and reinforce every seam with proper tape. To win a claim, photograph the damaged item and packaging before touching anything, keep all original materials until the claim closes, and file within the carrier’s deadline (60 days for UPS, FedEx domestic, and USPS; 21 days for FedEx international shipments).
Pack So It Doesn’t Get Damaged in the First Place
Start with the box itself. A carton that’s too big is one of the most common causes of damage: extra space lets the product slide, tumble, and slam into the walls with every bump in transit. Size the box so there’s just enough room for one to two inches of cushioning on each side, not extra room for the product to roam.
Match your cushioning to what’s inside. Bubble wrap or air pillows work for lightweight, semi-durable goods, but glass, ceramics, and other fragile items hold up better wrapped in honeycomb paper or thicker bubble wrap with a layer of crumpled paper or peanuts around them. Heavy or dense items — electronics, tools, machinery parts — need to be blocked and braced with foam inserts or corrugated dividers so they can’t shift and punch through a box wall under pressure.
Fill every void completely. The test: pick up the sealed box and give it a gentle shake. If you hear or feel movement, add more fill. An underfilled box lets contents collide with the walls; an overfilled one bulges the seams and weakens them, which is its own damage risk.
Double-box fragile or high-value items when possible — an inner box with its own cushioning nested inside an outer box with a cushioned gap between the two absorbs far more shock than a single layer of padding.
Seal it properly. Use 2- to 3-inch reinforced packing tape and apply it in an H-pattern: across both the top and bottom center seams, then along each side seam. Skip masking tape, cellophane tape, or string — carriers’ automated sorting equipment is rough on packages, and weak seals are a common failure point.
Label clearly and remove old labels or barcodes from reused boxes, since scanners can misread a stale label and route a fragile package the wrong way or through equipment it wasn’t packed for.
How to Document and File a Damage Claim
The moment you spot damage — whether you’re the sender or the customer forwarding it to you — stop and photograph before unpacking further. Shoot all sides of the outer box showing any crushing, punctures, or tape failures, then the inner packaging, then the damaged item itself. Carriers weigh photo evidence heavily, and the single most common reason damage claims get denied is packaging that inspectors judge as inadequate for the item shipped — so images that show your cushioning and box condition matter as much as images of the broken item.
Do not discard anything. Keep the box, all internal packaging materials, and the damaged product itself until the claim is fully resolved — carriers can request an in-person inspection, and missing materials is grounds for denial. Don’t reship or return the item in the meantime either.
Gather proof of value: the original invoice, order confirmation, or receipt showing what the item cost. Have your tracking number and, if applicable, proof you purchased extra insurance or declared a value on the shipment.
File promptly and within the deadline. UPS gives you 60 days from the scheduled delivery date; FedEx gives 60 calendar days from the ship date for U.S. shipments but only 21 days for international ones; USPS gives 60 days from the mailing date for damage or missing-contents claims. File online through the carrier’s claims portal (ups.com, fedex.com, or usps.com) rather than waiting for a paper form — it’s faster and creates a clearer digital trail.
Most damage claims are resolved within roughly one to two weeks once all documentation is submitted, though inspections can extend that timeline.
Tips and Common Mistakes
Don’t reuse boxes that are already crushed, water-stained, or structurally weakened — carriers can and do deny claims when the outer packaging itself looks compromised, regardless of what caused the damage.
Avoid packing peanuts alone for heavy items; they shift and settle in transit, leaving voids that open up mid-shipment even if the box felt full when you sealed it.
If you ship the same type of fragile product regularly, run your own drop test — package it, drop it from about three feet onto each side and corner, and open it up to check for damage before you commit to that packaging method at scale.
Keep a simple packaging log for high-value or fragile shipments: date, box size, cushioning used, and a photo of the sealed package. If a claim comes up weeks later, you’ll have your own evidence ready instead of scrambling to reconstruct what you did.
Never sign for a delivery marked as damaged without noting it in writing with the driver, and photograph it immediately in front of them if possible — this makes any follow-up claim substantially easier to win.

Reducing packaging damage and winning carrier claims FAQs
How long do I have to file a damage claim with UPS, FedEx, or USPS?
UPS and USPS both give you 60 days from the delivery or mailing date. FedEx gives 60 calendar days from the ship date for domestic U.S. shipments, but only 21 calendar days for international shipments.
What’s the single biggest reason carriers deny damage claims?
Inadequate packaging for the item shipped is the most common reason claims get denied, so photo evidence of your box, cushioning, and seams matters as much as photos of the damaged item itself.
Should I keep the damaged item and packaging after filing a claim?
Yes. Keep the box, all packing materials, and the damaged item until the claim is fully resolved — carriers may require an in-person inspection, and discarding materials early can get your claim denied.
Does double-boxing actually reduce damage?
Yes, for fragile or high-value items. Nesting a cushioned inner box inside a cushioned outer box adds an extra shock-absorbing layer that a single box with padding doesn’t provide.
