by spencer kYou pulled a recent fee report on your bulky or oversized SKUs and found a line item that wasn’t there a year ago: a packaging fee running a couple of dollars a unit, on top of everything else you’re already paying to store and ship that inventory. That’s the Amazon SIPP packaging fee, also called the non-SIPP fee, and as of January 15, 2026 it applies to any small-bulky or large-bulky item that isn’t enrolled in Amazon’s Ships in Product Packaging program. For sellers with slow-moving bulky stock, it’s one more reason the math on holding that inventory just got worse.
Here’s what SIPP actually requires, why the fee lands hardest on inventory you’re already unsure about, and when it makes more sense to sell that stock in bulk than to chase certification for it.
What the Amazon SIPP packaging fee actually is
SIPP stands for Ships in Product Packaging — Amazon’s program for letting an item ship in its own retail box or bag instead of getting boxed again in an Amazon-branded shipper. To enroll a SKU, your packaging has to hold up on its own through the fulfillment network: drops, stacking, conveyor handling, and (for anything fragile) independent ISTA-6 testing to prove it survives without an extra outer box.
Starting January 15, 2026, Amazon made SIPP effectively mandatory for bulky items. Any small-bulky or large-bulky product outside a short list of exempt categories that isn’t SIPP-certified now gets charged a per-unit non-SIPP packaging fee, calculated on dimensional weight. As of recent fee schedules, that fee has averaged roughly $2.07 per unit, with a published range from around $1.51 to $4.04 depending on the item’s size, and it applies to every unit shipped, not a one-time charge. Standard-size items aren’t required to enroll, but the financial incentive to do so is real there too.
In practice, this catches a lot of ordinary FBA inventory: folding furniture, large kitchen appliances, patio gear, big toys, fitness equipment, anything that ships in its own sturdy retail carton rather than something Amazon has to re-box. If you sell in those categories and haven’t looked at your SIPP enrollment status, the non-SIPP packaging fee is very likely already showing up on your settlement reports.
Why this hits your slow-moving bulky inventory hardest
A per-unit fee is easy to absorb on a SKU that turns over quickly and has real margin to spare. It’s a different story for the bulky item that’s been sitting since spring, already stacking storage fees that climb heading into Q4 and possibly an aged inventory surcharge on top. Add a non-SIPP packaging fee to every unit that does eventually sell, and a SKU that was only marginally worth keeping before January can be quietly losing money now, even though nothing about the listing or the sell-through rate has changed.
It compounds with other 2026 changes, too. Amazon also added a 3.5% fuel and logistics surcharge on fulfillment fees this year, and discontinued its own prep and labeling services in January, shifting more compliance cost onto sellers directly. None of these are large individually. Stacked on bulky, aging, slow-selling inventory, they add up to a real drag on recovery.
Why SIPP certification isn’t always worth chasing
Getting a SKU SIPP-certified isn’t free or instant. It usually means redesigning packaging so it can survive the fulfillment network on its own, paying for independent testing on anything fragile, and going through Amazon’s review process — real time and real money, spent on packaging engineering rather than inventory. For a core SKU you plan to sell for years, that investment can pay for itself many times over in avoided fees. For a slow-moving bulky item, a seasonal product that missed its window, or a SKU you’re already lukewarm on, it’s money spent making a marginal product a little less unprofitable, not money spent making it good.
Before you commit to a packaging redesign, run the numbers the way you would for any other fee change: pull your unit volume and margin on the specific SKU, multiply the non-SIPP fee by expected units sold over the next six to twelve months, and compare that to what certification would actually cost to implement. On a strong seller, certification usually wins. On stock you’ve already been meaning to deal with, the fee is often just confirmation that it’s time to move it rather than fix it.
When it makes more sense to liquidate than to certify
If a bulky SKU was already thin on margin, slow to sell, or both, the non-SIPP fee tips the scale further toward selling it off rather than investing in a packaging fix you may not use for long. Every month it sits, you’re paying storage, possibly an aging surcharge, and now a packaging penalty on whatever finally ships — three separate costs eating into a recovery that was already uncertain. Liquidating the batch converts all of that uncertainty into cash in one move, instead of a slow drip of fees while you decide.
If you go this route, the same fundamentals apply as with any bulk sale: group similar SKUs together, describe condition honestly, and get more than one offer before committing — the general approach to getting top dollar when liquidating inventory holds here too, and bulky items in particular benefit from buyers who already have freight and pallet logistics worked out.

Frequently asked questions about the Amazon SIPP packaging fee
Do I have to enroll every product in SIPP?
Only certain bulky items are effectively required to enroll — products above roughly 18″ x 14″ x 8″ or 20 pounds, outside a short list of exempt categories, now get charged the non-SIPP packaging fee if they aren’t certified. Standard-size items can enroll voluntarily, and it’s usually worth it for high-volume SKUs, but it isn’t mandatory for them.
How much is the non-SIPP packaging fee per unit?
As of recent fee schedules, Amazon has cited an average of roughly $2.07 per unit for non-SIPP bulky items, with a range from about $1.51 to $4.04 depending on dimensional weight. Check your own fee reports for the exact number on a given SKU rather than relying on the average, since it varies by size.
Is it worth certifying a slow-moving item just to avoid the fee?
Usually not. Certification takes real packaging redesign and, for fragile items, independent testing — costs that make sense to absorb on a SKU you plan to keep selling for years, but rarely pencil out on inventory that’s already slow, aging, or on the fence. For that stock, selling it off tends to recover more than fixing its packaging would.
Does the non-SIPP fee apply to items already in an Amazon fulfillment center?
Yes. The fee applies to eligible bulky units going forward based on their SIPP enrollment status, not just new shipments, so existing inventory that isn’t certified keeps accruing the fee on every unit that sells until you either get it certified or move it out.
