What shipping insurance actually covers
Package insurance is bought one shipment at a time and pays out against three events:
- Loss: the parcel never arrives and tracking cannot account for it after the carrier's required search period.
- Damage: it arrives crushed, broken, or contaminated, and the damage happened in transit.
- Theft in the network: the parcel is taken while the carrier has custody, before it is marked delivered.
Two details catch shippers out. First, coverage is capped at the value you declared, so under-declaring to save a few cents caps your own payout. Second, most policies reimburse the actual value of the goods, documented by an invoice or cost record, not the retail price with your margin on top. Some programs also refund the postage on a lost parcel. The definition of value sits in the policy language, so read it before you need it.
What shipping insurance does not cover
- Porch theft after delivery. Once tracking says delivered, standard coverage usually ends.
- Delay on its own. A late parcel is a service problem, not a covered loss. See what a delivery exception means before you open a claim.
- Prohibited and restricted goods. Every carrier publishes a list of items that cannot be insured or that carry a lower liability cap, commonly perishables, live goods, currency, and certain jewelry and electronics.
- Consequential losses. Lost sales, the cost of expediting a replacement, and customer goodwill are not reimbursed.
- Inadequate packaging. A common denial reason, covered in detail below.
- Bad address data and refused or undeliverable shipments.
Declared value vs shipping insurance
This distinction decides how a claim goes, and most guides skip it. When you enter a declared value with a major parcel carrier, you are usually not buying an insurance policy. You are raising the ceiling on the carrier's liability. The carrier still only pays if you can show it caused the loss or damage, and its tariff still governs the outcome.
A true third-party policy is an insurance contract with named perils, its own exclusions, and its own claims adjuster. It does not hinge on proving the carrier was at fault. USPS is the outlier among the big three: it sells actual insurance. UPS and FedEx declared value is a liability limit. Same fee on the label, very different footing when something goes wrong.
Carrier coverage vs third-party insurance vs self-insuring
| Carrier coverage | Third-party insurer | Self-insuring | |
|---|---|---|---|
| What it is | Declared value raising carrier liability, or USPS insurance | A parcel or cargo policy from an insurance provider | No policy; you absorb losses and replace the item |
| Where you buy it | At the label, in the carrier account or shipping software | Insurer portal or an app inside your shipping platform | Nowhere; it is a budget line |
| Priced by | Declared value, in bands or per hundred dollars | Declared value, often at a negotiated rate at volume | Your actual loss rate |
| Claim basis | Carrier fault under its tariff | Covered perils under the policy | You decide, instantly |
| Strength | One click, no separate vendor, no minimums | Cheaper at volume, broader perils, faster adjudication | No premiums, no paperwork, no denials |
| Weakness | Costly per parcel, fault-based, slow on disputes | Another account, and volume commitments may apply | One bad month lands entirely on your cash flow |
| Best for | Occasional high-value or one-off shipments | Steady volume with real exposure per parcel | Low-value, high-volume, low-claim-rate catalogs |
Is shipping insurance worth it?
Buy coverage when:
- The replacement cost is high enough that eating it would sting.
- The item is fragile, heavy, oddly shaped, or otherwise hard to protect.
- You ship rarely, so you have no loss history to average the risk across.
- It is a wholesale or retail pallet where one shipment carries many units of value.
- The item has strong resale demand, which correlates with theft in transit.
Skip it, or self-insure, when:
- The unit cost is low and your historical claim rate is low.
- The premium approaches the cost of just replacing the item.
- You already carry a breakage allowance inside COGS.
The honest test is arithmetic: compare the per-parcel premium against your expected loss, meaning your probability of loss or damage multiplied by replacement cost, plus the labor of handling the claim. Only your own shipping data gives you that probability, which is why tracking claims by lane, carrier, and SKU is worth the effort.
The math of self-insuring at volume
Insurance is priced so the insurer profits across the whole pool. If your loss rate sits at or below the pool average, insuring every parcel means paying claims costs plus the insurer's margin on shipments that were never going to fail. That is why most scaled brands stop insuring everything.
Run it like this:
- Pull a full quarter: total parcels shipped, parcels lost or damaged, and the replacement cost of each.
- Divide total replacement cost by total parcels. That is your loss cost per shipment.
- Compare it to the average premium per shipment you would pay to insure all of them.
- If the premium is meaningfully higher, set a declared value threshold. Below it, self-insure. Above it, buy coverage.
- Redirect the premium you no longer spend into a replacement reserve so a bad month is funded rather than absorbed.
Then watch the tail. Exposure is rarely spread evenly. A small group of high-value or breakable SKUs usually carries most of the risk, so insure those specifically instead of taxing the entire catalog.
What voids a shipping insurance claim
Packaging is one of the most common denial reasons, and it is the one entirely under your control. Adjusters look for whether the box could reasonably survive normal handling.
- Too little void fill. Product touching the box wall, or rattling inside it, reads as under-packed. Proper dunnage is what the adjuster is looking for.
- Reused or fatigued cartons and single-wall board under heavy contents.
- Fragile items not double-boxed when the carrier's own packaging guidance calls for it.
- Value under-declared or declared with no supporting invoice.
- Packaging thrown away before the carrier could inspect it.
- Filing late. Claim windows differ by carrier and differ again between loss and damage, so check the current terms for the service you used.
A "Fragile" sticker is not protection and carries no weight in a claim. Getting the packaging engineering right is both the cheapest way to avoid damage and the thing that keeps a claim alive when damage happens anyway.
How to file a claim and what documentation you need
- Confirm the parcel is genuinely lost, not just sitting on an exception scan.
- Wait out the carrier's required search period for lost parcels. Filing before it elapses gets the claim rejected on procedure.
- Gather documentation: tracking number, the label or postage receipt, proof that coverage was purchased or value declared, an invoice or cost record establishing value, photos of the item, photos of the inner and outer packaging, and a written description of the damage.
- File with whoever sold the coverage, not whoever moved the box.
- Keep the shipment and all packing materials until the claim closes, in case an inspection is requested.
- Handle the customer separately and immediately. Reship or refund now, then pursue the claim on your own time. Tying the customer's resolution to the claim timeline is how a recoverable loss turns into a lost customer. A clean returns and replacement process makes that decision routine.
Where a 3PL fits
Most damage claims are decided long before the parcel is scanned. They are decided at the pack bench, by carton choice, void fill, and whether the packer followed a documented spec for that SKU. A 3PL that packs to a written standard, photographs high-value outbounds, and keeps carrier claim records by lane gives you both fewer claims and better evidence on the ones you file. RitePrep runs its own Austin, Texas warehouse and holds 99.9% pick accuracy, and part of that discipline is packing to survive the trip rather than packing to save a nickel. If you are deciding what to insure, start by asking your fulfillment partner for your real damage rate by SKU. That number, not a generic rule of thumb, tells you where coverage earns its cost.
