Partnered Carrier or Own Carrier: The Reimbursement Rule

By Bernardo Campelo, Forbes Business Council E-Commerce Leader, Amazon SPN Certified provider, Amazon SP-API authorized partner, and Founder of PrepVia.

Picture a pallet that leaves a warehouse dock on a Tuesday, signed out on a bill of lading, and never reaches the fulfillment center. Who pays? The tempting answer is that Amazon covers freight bought through its partnered carrier program, and your trucker covers freight you booked yourself.

Amazon's own contract does not support that answer. The Amazon Partnered Carrier Agreement makes you the shipper of record and Amazon the payer of record, and it keeps title and risk of loss with you. The policy that reimburses inventory lost on the way in does not make eligibility depend on which carrier you used.

Partnered Carrier changes who buys and pays for the freight. It does not change who carries the risk or which reimbursement policy applies. What it changes is the evidence: who holds the bill of lading, who holds the tracking, and what you must hand Amazon before a claim is paid.

What the Partnered Carrier Agreement Actually Says

The page that settles the liability question is the Amazon Partnered Carrier Agreement, and it is short. It says Amazon may, at its option, let you ship units at your expense using discounted rates it makes available for certain carriers. Then it assigns the roles.

As between you, Amazon and the carrier, the Agreement says "you will be the shipper of record," and Amazon will be the payer of record for units shipped at the discounted rates. Title and risk of loss for those units remain with you. Amazon providing the rates, the Agreement adds, does not create any liability or responsibility for Amazon for any delay, damage or loss during shipment.

Three things follow. First, Amazon paying the carrier is a billing arrangement: the Partnered Carrier program page says the cost is billed to your account as an inbound transportation charge and shows as a service fee in your Payments report. Second, title and risk of loss stay with you while the freight moves. Third, you authorize the carrier to give Amazon all shipment tracking information.

That makes partnered freight a pricing and booking choice, not an insurance policy. If your cargo coverage assumes Amazon carries the transit risk on partnered loads, the Agreement says otherwise.

What Amazon Does, and Does Not Do, on a Partnered Load

The program still does real work. According to the program page, partnered options cover small parcel, LTL, intermodal and full truckload shipments within the 48 contiguous states, at rates Amazon negotiated with its partnered carriers, and small parcel typically goes via UPS. For pallets, Amazon selects the lowest-cost carrier rate for your freight-ready date, lets you switch with Change carrier, and puts the assigned carrier on the bill of lading you print from Seller Central.

What Amazon does not do is load the truck or count your pallets. The page makes you responsible for loading the shipment in full, has your warehouse clerk and the driver sign the bill of lading after confirming it matches the pallets on the truck, and tells you to keep a signed copy. If a pickup is missed and no new date appears, it tells you to contact the carrier directly.

When the Carrier's Scale Disagrees With Yours

Weight has its own rules on partnered freight, and they cut one way. The Agreement says you may be charged more if the carrier finds the freight heavier than the weight you submitted, and may be charged the full estimate even if it finds the freight lighter. The Partnered Carrier program FAQ says the final cost follows the final carrier assigned and the weights, dimensions and freight class measured in transit.

If you have proof the audited figures are wrong, the FAQ points you to the Inbound Performance dashboard: Resolve on the Inaccurate Transportation Weight/Dims defect, then Submit dispute. The program page warns that inaccurate shipment information results in charged fee adjustments and may result in blocked future shipments. The dispute side is covered in partnered carrier fee adjustments.

The Reimbursement Policy Does Not Ask Who Bought the Freight

The page that governs inventory lost on the way in is FBA inventory reimbursement policy: Shipment to Amazon claims. It applies to items lost or damaged when you ship them to Amazon, and its eligibility rules do not separate partnered freight from your own carrier.

The window opens once the shipment shows as eligible for investigation in the Status column on the Contents tab of the Summary page. It closes nine months after the verified date of delivery to an Amazon fulfillment center or to a third-party facility operated on Amazon's behalf. You may file one claim per shipment, and additional claims for the same shipment are declined.

Amazon asks for the shipment ID, proof of inventory ownership, such as a supplier invoice showing the date of purchase, product names and quantity, and proof of delivery. For LTL and full truckload, that is a document showing the number of boxes and the total weight at carrier pickup, stamped by Amazon to confirm the shipment was received and signed for at the fulfillment center. The policy notes that your carrier should have a copy. For small parcel, it is an active tracking ID for each package.

Only one line names the carrier choice. If you did not use an Amazon partnered carrier on small parcel and did not provide tracking when you created the shipment, you must enter it before you can be reimbursed. The program page says the same from the other side: partnered small parcel comes with Seller Central labels, delivery tracking and coverage for lost or damaged items under the FBA inventory reimbursement policy. Your own carrier reaches the same policy once you put the tracking there.

After its investigation, Amazon confirms whether the claim is eligible for replacement or reimbursement, and in some cases it may reconcile the shipment. Sellers with many shipping problems may face extra monitoring that could delay future reimbursements. Why claims get denied is covered in why Amazon denied your FBA reimbursement.

What the Policy Does Not Describe

The nine-month clock runs from a verified delivery, and the LTL proof is a document Amazon stamps at the fulfillment center. The policy page does not describe a separate path for a load that never reaches an Amazon building. If a whole pallet vanishes between the two docks, the remaining places to look are the carrier and the bill of lading, and on a partnered load the Agreement has already put that risk with you. A day-by-day plan is in what to do when an FBA shipment is stuck in transit.

Partnered vs Own Carrier: What Actually Changes

Side by side, the reimbursement rows come out the same. The rows that differ are about who books, who pays and who holds which piece of paper.

The Evidence File, Built Before the Truck Leaves

Because the rule is the same and the paperwork is not, the useful question is what file each path leaves you with. Build it at pickup, not after the shipment shows as eligible for investigation.

The mechanics of that paper trail are covered step by step in BOL, POD and the FBA paper trail. A different problem, where Amazon received the load but counted fewer units than you declared, starts somewhere else: see declared versus received discrepancies.

Two Clocks, Two Counterparties

A loss can put you on two clocks at once, and they belong to different parties. The carrier clock is set by the bill of lading and the carrier's own terms, inside a federal floor.

Under 49 U.S.C. 14706, an interstate motor carrier must issue a receipt or bill of lading for the property it receives, and it is liable to the person entitled to recover under that document for the actual loss or injury to the property. Subsection (e) bars a carrier from giving less than nine months to file a claim, or less than two years to sue, with the two years counted from the date it gives written notice that it disallowed any part of the claim.

What Counts as a Claim Against a Carrier

Under 49 CFR Part 370, a claim is a written communication, filed with a proper carrier within the time limits in the bill of lading, that identifies the shipment, asserts liability and asks for a specified or determinable amount of money. A notation of shortage or damage on a delivery receipt or freight bill, standing alone, is not a claim. The carrier must acknowledge a claim in writing within 30 days unless it has already paid or declined it, and must pay, decline or make a firm settlement offer in writing within 120 days or, if it cannot, explain the delay in writing then and every 60 days while the claim is pending.

One more line matters for Amazon inbound. When a claim for loss of an entire package or shipment cannot be authenticated any other way, the carrier must obtain a certified statement from the consignee that the property was not received from any other source. If the consignee on the bill of lading is an Amazon site, that statement depends on a party you do not control, so raise a missing load early. This is general information, not legal advice: the bill of lading, the tariff and your freight counsel decide what applies to a specific shipment, including who is entitled to file.

How to Choose Between the Two Paths

With the liability myth removed, four questions settle most lanes.

Wholesale accounts moving case packs and pallets face this choice on every load, and that workflow is laid out on our wholesale and distribution page.

At PrepVia, most of the freight that leaves our Miami dock moves as LTL or FTL on Amazon partnered carriers, booked through our own SP-API integration. That choice does not move the risk of loss to Amazon. What we control is the file: every carton is counted against the packing list and the bill of lading when it arrives, discrepancies are reported with evidence within 24 hours of arrival, and the bill of lading and proof of delivery are stored with the shipment. As an Amazon SPN Certified provider with a 24-36 hours prep window, we build that file before anyone needs it.

Frequently Asked Questions

What is the difference between Amazon Partnered Carrier and own carrier?

With Amazon Partnered Carrier, Amazon selects the carrier at its negotiated rates, generates the LTL bill of lading, pays the carrier as payer of record and bills the cost to your account. With your own carrier, you book and pay the carrier yourself. On partnered freight you remain the shipper of record under the Partnered Carrier Agreement, and title and risk of loss stay with you.

Does Amazon take responsibility when a partnered carrier loses or damages my shipment?

Not under the Partnered Carrier Agreement, which keeps title and risk of loss with you and says Amazon providing the rates creates no liability or responsibility for Amazon for delay, damage or loss during shipment. Separately, the Shipment to Amazon claims policy covers items lost or damaged on the way to Amazon, and Amazon decides after its investigation whether a claim is eligible for replacement or reimbursement.

Can I file an FBA reimbursement claim on a shipment I sent with my own carrier?

Yes. The Shipment to Amazon claims policy does not limit eligibility to partnered freight, and the same window, one-claim limit and proof list apply. The one extra step is for small parcel: if you did not provide tracking at shipment creation, you must enter it before you can be reimbursed.

What proof does Amazon ask for on a Shipment to Amazon claim?

The Amazon shipment ID, proof of inventory ownership such as a supplier invoice showing the date of purchase, product names and quantity, and proof of delivery. For LTL and FTL, proof of delivery is a document showing the number of boxes and the total weight at carrier pickup, stamped by Amazon at the fulfillment center. For small parcel, it is an active tracking ID for each package.

How long do I have to file a claim?

With Amazon, from the moment the shipment shows as eligible for investigation until nine months after the verified delivery date, with one claim per shipment. With an interstate motor carrier, the bill of lading sets the time limit, but 49 U.S.C. 14706(e) bars less than nine months to file or less than two years to sue after a written disallowance. The documents for your specific shipment control.

What happens if the carrier weighs my freight differently than I declared?

On partnered freight, the Agreement says you may be charged more if the carrier finds the freight heavier, and may still be charged the full estimate if it finds the freight lighter. The final cost follows the weights, dimensions and freight class measured in transit. With proof that the audited figures are wrong, you can dispute them from the Inbound Performance dashboard through the Inaccurate Transportation Weight/Dims defect.

Should I always choose Amazon Partnered Carrier over my own carrier?

Not for liability reasons, because partnered freight does not move the risk of loss to Amazon. Choose it when the lane qualifies and the rate is better. Choose your own carrier when partnered service is not available, for example from Hawaii, Alaska or a port terminal, or when your own quote is better for the same freight.

Final Take

The pallet that never arrives is a hard week on either path. It is harder when the plan was built on a rule that is not in the contract.

Amazon Partnered Carrier is a way to buy freight at Amazon's negotiated rates, with Amazon choosing the carrier, generating the bill of lading, paying the carrier and billing the cost to your account. The Agreement keeps you as shipper of record and keeps the risk of loss with you. The Shipment to Amazon claims policy is the same on both paths: the same nine-month window, the same one-claim limit, the same proof.

What separates the paths is who holds which document. That is an operations question, answered at the dock on the day of pickup by whoever counts the cartons and signs the bill of lading. Choose the path the lane and the rate support, and build the file as if you will need it, because the Amazon policy asks for it and the federal claim rules assume you have it.
