Who exactly are bulky-item sellers working for? One 150-pound bulky item: $140 for FBA inbound, and another $163 loss on returns!
Created on 08.14
Sellers dealing with bulky and oversized items on Amazon have probably all had this moment:
After struggling with the listing for two or three months and spending nearly $20,000 on ads, you finally push the ranking up and sales start rolling in.
Looking at the backend, you think this wave is secure.
But when you settle the accounts at the end of the month, there's barely any profit.
Digging into the data, you realize—all the money you earned went to FBA.
Many sellers wonder: bulky categories clearly have high gross margins and less competition than standard items, so why does it get more tiring and less profitable the longer you do it?

Today, we'll break down the real cost of a 150-pound treadmill and calculate the full 2026 bulky FBA bill in one go.
01 The first trap for bulky sellers: shipping is just the "entry fee"
Sellers used to standard items might think FBA delivery fees are just a few dollars, right?
However, the charging logic for large and heavy goods is completely different from that of general goods.
1. Amazon has a completely different charging logic for oversized and overweight products.
A 150-pound treadmill falls into the 'large item' category in Amazon's charging system, with a basic FBA delivery fee ranging from $80 to $140, depending on the warehouse area and whether it is peak season.

2. Do you think that’s the end? There are additional fees.
In 2026, Amazon divided large items into 'small large items' and 'large large items'. If your product is not included in SIPP (Packaging Optimization Program), an additional charge applies: small large item: +$1.51, large large item: +$4.04
3. From October to January each year, an additional peak season surcharge is added. The bulky size tier surcharge rises again—the heavier the item, the steeper the increase.

4. And that's not even counting storage fees.
Monthly storage fees for bulky items are $0.56/cubic foot in the off-season, and double to $2.40/cubic foot in the peak season.
A treadmill sitting in a warehouse for a month costs a significant amount.
Many sellers think $140 is the total cost, but in reality, it's just the "entry ticket" to the warehouse.
02 The most fatal inversion: one return hurts more than one shipment—losing $163
If delivery fees are "open robbery," then bulky item returns are an "assassination" on your profits.
Many bulky sellers don't know that when FBA processes a return, the original delivery fee is not refunded. You paid $110 to ship it out, the customer returns it, and that $110 is wasted.
Then Amazon will charge you a return processing fee.
After the new policy in June 2026, the return processing fee for large items increased by 80%. A 150-pound treadmill is classified as a 'large item', with a single return processing fee of $5.
Storage fees during the return period continue to apply. The return processing cycle usually takes 7 to 14 days, during which large items continue to occupy warehouse space, incurring additional storage fees.
Another easily overlooked aspect: return labels. Starting from February 2026, sellers on the US site are required to use prepaid return labels, with all reverse logistics costs borne by the seller.
A return process looks like this:
Original delivery fee (non-refundable) $110 + return processing fee $5 + storage fee during return period $15 + return label cost (charged as incurred), totaling over $130
Send one order for $140, return one order for $130+. One in and one out, directly losing $270 per item.
Adding product residual value loss and sunk advertising costs, the actual loss easily exceeds $300.
Equivalent to returning one order, selling three orders for free.
03 Hidden costs are the real profit black hole
The visible accounts are settled, but there are three 'invisible costs'.
First cost: wasted advertising expenses.
From the time a customer clicks on an ad to placing an order, you spend $10-$30 on customer acquisition costs. After a return, this money will not be refunded to you.
It's like paying to drive traffic, only to end up with a return.

Second cost: The returned product is no longer worth much.
A 150-pound treadmill, when returned, most likely has damaged packaging, missing accessories, and signs of use. Amazon won't allow it to be sold as new.

Third item: High return rate label.
Products with a return rate exceeding 25% of similar items will be forcibly labeled by Amazon as 'high return rate'.
Once labeled, the conversion rate visibly declines—your listing is basically sentenced to 'death penalty'.

04 Real bulk accounting: If you sell 100 orders, how much can you actually save?
We simulate based on the normal order ratio of large item sellers: sell 100 units, return 15 units, let's do the math:
Sales ($599×100) $59,900
Less: Product cost + first leg ($300×100) -$30,000
Less: FBA delivery fee ($110×100) -$11,000
Less: Return cost (15 units×$130) -$1,950
Net profit on paper $16,950
Does it seem like there is still a 28% profit?
That’s without considering advertising costs, storage fees, return residual value losses, and the conversion decline caused by the high return rate label.
Taking all these into account, the actual net profit margin is likely to fall below 15%.
You have invested effort in product selection, time in operations, funds in stock preparation, and budget in advertising, but in the end, what you get is less than if you had just saved the money in a bank.
It's not that your operations are poor; it's that in the bulky goods track, using the FBA model inherently comes with a loss-making flaw.

05 It's not that bulky items don't make money—it's that the logistics channel is wrong
Standard items can go through FBA because delivery fees account for a low percentage, return rates are controllable, and scale can dilute costs.
But bulky items are the complete opposite—the higher the volume, the more money FBA takes from you.
Home, fitness, and outdoor bulky items have stable market demand, high average order values, and ample gross margin space.

Sellers who make money never rely on heavy ad spending or mass inventory; they rely on meticulous logistics cost control and loss prevention.
The core capabilities for bulky North American logistics come down to three things: owned trucking fleet, local direct operations, and integrated delivery and installation.
Having deeply cultivated cross-border logistics in North America for many years, we understand the pain points of large item sellers: price increases during peak seasons, unstable warehouse space, damage during transit, unresolved returns, and uncontrolled costs. Whale Navigation's self-operated truck service for large items in North America focuses on solving these problems:
1. Full self-operated truck delivery, no middleman subcontracting
Own 26/53FT heavy trucks and a three-axle heavy-duty chassis fleet, with dedicated warehouse space locked for large items.
No price increases during peak seasons, no container delays, no last-minute channel changes.
2. Direct operations at nine major ports, nearby container pickup without delays
Covering nine core ports across the United States, including Los Angeles, Long Beach, New York, Savannah, and Houston, our local team picks up containers nearby, quickly unpacks, and delivers directly.
Eliminate port delays, transit delays, and secondary price increases; if a container stays an extra day, the seller loses another day, and we strictly control the timeliness throughout.
3. Dedicated large item delivery and installation, crushing ordinary truck delivery
We provide hydraulic tailgate professional trucks with two-person operations: unloading → entering the home → unpacking → installation → cleaning up, completed in one stop.
Suitable for oversized, heavy goods delivery to private addresses, overseas warehouse replenishment, and FBA compliant warehousing in all scenarios.
4. Supporting solutions for large item return residual value
For the return losses that everyone is most troubled by, we provide exclusive reverse logistics solutions: return warehouse inspection, refurbishment, compliant distribution, and low-cost disposal.
No longer let returns directly equal write-offs, maximize the recovery of product residual value, and offset FBA's high return black hole.
5. Timely delivery, stable after-sales, no hidden fees
98% on-time delivery rate, 99.8% signature compliance rate, fully transparent billing, no temporary surcharges, no hidden deductions.
06 Large-item sellers, stop working for FBA
In the large-item track, profits have always been there—they're just being eaten up by unsuitable logistics channels.
A 150-pound treadmill costs $300 in losses going in and out of FBA—this is a wrong channel choice.
Profit isn't something you endure your way into; it's something you squeeze out and select for.
