For years this was a small discount you could reasonably skip. It is now a recurring fee you pay on every unit for not bothering.
Ships in Product Packaging launched in February 2024 as a rebrand and expansion of the older Ships in Own Container program. The pitch was straightforward: certify that your retail packaging can survive shipping on its own, and Amazon stops adding a box around it, charging you less because it uses less material and less labor.
Most sellers looked at a discount measured in cents and decided it was not worth a lab test. That was a defensible reading of the program as it existed.
Two changes since have inverted it. Certification became mandatory above a size and weight threshold, and non-enrolled bulky products began incurring a packaging fee in January 2026. The question is no longer whether a discount justifies the effort. It is whether you want to keep paying a penalty indefinitely on products that could qualify.
What SIPP Actually Is
A SIPP-certified product ships to the customer in its own retail packaging. Amazon applies a shipping label to the exterior of your box and sends it. No overbox, no dunnage, no Amazon-branded packaging around yours.
For that to work, your retail package has to function as a shipping container rather than as shelf display packaging, and Amazon verifies that through testing rather than taking your word for it.
Ships in Product Packaging (SIPP). An Amazon program certifying that a product's retail packaging is durable enough to ship to a customer without an additional Amazon box. Launched in February 2024 as a rebrand and expansion of the Ships in Own Container program, with sellers previously certified under SIOC carried across automatically. Certified products receive reduced fulfillment fees and are exempt from packaging fees applied to non-enrolled bulky items.
If you were certified under SIOC previously, reporting indicates you were enrolled in SIPP automatically and continue receiving the fee benefits, so check your enrollment status before assuming you need to start from nothing.
The Two Tiers
SIPP is not a single standard. There are two, and the harder one carries requirements that have nothing to do with durability.
| Tier | What It Requires | Practical Read |
|---|---|---|
| SIOC (Tier 2) | Package survives Amazon's ISTA 6 drop and handling sequence in its own container | The achievable tier for most products. Durability only. |
| Frustration-Free Packaging (Tier 1) | Everything in SIOC, plus fully curbside recyclable and all contents removable within 120 seconds | Harder. Rules out blister packs, clamshells, loose fill, and plastic inserts. |
| Minimum dimensions | At least 6 by 4 by 0.375 inches | Small items cannot carry a shipping label and are excluded on size alone. |
The 120-second rule in the Tier 1 standard is the one that catches product teams. It is an openability requirement measuring how long it takes a customer to get everything out, and it eliminates a lot of packaging that exists specifically to look good on a shelf or resist theft in a retail environment.
For most sellers Tier 2 is the target. It delivers the fee treatment without forcing a packaging redesign around recyclability and openability, and it is achievable with a sturdy corrugated retail box.
What It Removes From Your Workflow
The fee discount is the headline. The operational effect is arguably worth more, particularly now that prep is entirely your responsibility.
A SIPP-certified unit needs a label on its own packaging. That is it. No poly bag, no overbox, no protective materials added by you or by anyone you pay. For a product that previously required bagging or boxing before inbound, certification removes a per-unit prep step permanently rather than making it cheaper.
That compounds with materials. Every bag, box, and length of bubble wrap you no longer buy is cost removed rather than shifted, and the storage space those materials occupied comes back too.
Third-party prep centers can handle SIPP-enrolled shipments by applying the FNSKU label directly to your product packaging instead of over-boxing. Confirm your provider knows the requirements and pilot one small shipment before moving full volume, because a provider running an unmodified workflow will happily over-box units you certified specifically to avoid over-boxing.
The dimensional benefit is real too. Removing an overbox reduces the shipped dimensions, and dimensions drive size tier, which drives fulfillment fees independently of the SIPP discount itself. On products sitting near a tier boundary that secondary effect can exceed the primary one.
The 2026 Fee That Changed The Math
This is why the program moved from optional to urgent, and it is the part most older articles do not carry.
Per Amazon's packaging program FAQ, new packaging fees took effect for small bulky and large bulky products in the US starting January 15, 2026, and for oversize products in the EU from February 1, 2026. The fees apply to items not enrolled in Ships in Product Packaging that require additional packaging. Products already enrolled are unaffected and continue receiving reduced fulfillment fees.
The size of that fee is where sources disagree, so treat any single number carefully.
| Reported Figure | How It Is Described | Confidence |
|---|---|---|
| $1.51 to $4.04 per unit | Range by dimensional weight for small and large bulky | Third-party reporting. |
| $1.51 to $4.40 per unit | Same range, different upper bound | Third-party reporting. Conflicts with the above. |
| About $2.07 per unit average | Average across affected units, on dimensional weight | Third-party, cited to Seller Central. |
| $0.04 to $1.32 per unit | Discount for enrolled standard-size products | Consistently reported across sources. |
What is not in dispute is the direction and the structure. Enrolled bulky products avoid a fee that non-enrolled ones pay on every unit, indefinitely, and enrolled standard products additionally receive a discount. Pull your own figures from Seller Central rather than planning around a published range.
The compounding effect is what makes this urgent rather than merely annoying. A penalty of roughly two dollars a unit on a product moving two thousand units a month is a recurring cost of a scale that dwarfs a one-off certification test, and it continues for as long as the SKU stays non-compliant.
Who Must, Who May, Who Cannot
Three groups, and knowing which one a product is in determines whether this is a decision or an obligation.
Packaging over 18 by 14 by 8 inches, or weight over 20 pounds, outside excluded categories. Per Amazon's packaging FAQ this is required, not optional.
Small and large bulky products below the mandatory threshold. Optional, but non-enrollment now carries the packaging fee, so the arithmetic usually favors certifying.
Standard-size products. No penalty for staying out, a per-unit discount for coming in. Volume decides whether the test pays back.
Dangerous goods with UN transportation requirements, hazardous materials, Amazon Fresh items, and products under the 6 by 4 by 0.375 inch minimum.
On group four, Amazon's FAQ notes that currently ineligible products such as dangerous goods and size-restricted items may qualify in the future, and recommends periodically reviewing eligibility in the enrollment portal. Reporting indicates an ineligibility tab became available from February 15, 2026, which is where to check rather than guessing.
Anything with UN transportation requirements is excluded outright and no amount of packaging testing changes that. That covers standalone lithium batteries, flammable liquids, and active pesticide formulations among others, which is worth knowing before you spend money testing a package that cannot qualify regardless of how well it performs.
The Certification Path
The process is more tractable than the phrase "lab certification" suggests, particularly for durable products in sturdy boxes.
- Review your eligible ASINs. Amazon identifies products that may qualify based on packaging data it already holds. Start from that list rather than building your own.
- Confirm the packaging meets the standard. Minimum dimensions, and honest assessment of whether the box survives handling without an overbox.
- Choose your tier. Tier 2 for most products. Tier 1 only if your packaging already meets the recyclability and 120-second openability requirements.
- Test. Self-certification is available for some products; fragile items require independent lab testing against the ISTA 6 standard for Amazon.
- Upload certification where required and wait. Reporting puts Amazon's review at five to seven business days.
- Confirm the workflow change. Inbound shipments now ship in their own packaging. Tell whoever preps your inventory, because this is the step that silently fails.
Step six is where real-world implementations go wrong. Certification is a data change in Amazon's system. If your prep center or your own team keeps over-boxing certified units out of habit, you have paid for a certification and captured none of the operational benefit.
Testing Costs And Group Testing
Third-party reporting puts independent ISTA 6 lab testing in the range of $300 to $2,000 per test, varying with product complexity and lab. That is the number that historically stopped sellers, and it is why the group testing approach matters.
Reporting on the program describes testing the largest or heaviest product within a group of similar products, with a pass qualifying comparable products in that group. If your catalog contains variations of the same product in different sizes, or several products sharing a packaging format, that turns a per-SKU cost into a per-family cost.
That contrast is the whole decision. Bulky products facing the packaging fee have an obvious case. Low-volume standard products earning a few cents a unit do not, and no amount of enthusiasm for packaging sustainability changes the arithmetic.
The Real Risk: Decertification
Here is the tradeoff that matters, and it is not the one usually named.
Certification is conditional on performance in the real world. If products certified under SIPP arrive damaged at an elevated rate, Amazon removes the status. One source describes the threshold as Amazon decertifying when it has 90 percent confidence that the damage rate exceeds 5 percent, or that non-compliance exceeds 5 percent. That specific statistical framing comes from a single third-party source, so treat the exact figure as reported rather than confirmed, and the principle as sound.
Certification says your packaging passed a test. Decertification says it failed reality. The gap between those two is where the risk lives, and it shows up as damaged units and negative reviews before it shows up as a status change.
The failure sequence matters more than the status loss. Before Amazon decertifies anything, you have shipped damaged products to customers. Those produce returns, negative reviews, and a hit to the metrics that drive your visibility, and none of that is recovered by simply reverting to an overbox afterwards.
So the honest way to approach certification is to pass the test with margin rather than barely. A package that squeaks through a drop sequence in a lab is a package that will fail in the tail of real-world handling, and the tail is where damage rates come from. If your packaging passed marginally, strengthen it before enrolling rather than after being decertified.
This also argues for watching return and damage data closely for the first few months after enrolling on any SKU. Our guides to reducing return rate and reverse logistics cover the measurement side, and the relevant signal here is a change in damage-related returns specifically rather than returns overall.
The Branding Effect Most Articles Get Backwards
There is a version of this analysis, and I have seen it repeatedly, claiming SIPP costs you the unboxing experience because your product no longer arrives in Amazon packaging you could have branded.
That has it exactly backwards. Without SIPP, your product arrives inside a plain Amazon box, and the customer's first impression is Amazon's packaging rather than yours. With SIPP, your retail packaging is what shows up at the door with a label on it. The branding effect is positive.
The genuine consideration is different and worth naming properly. Your retail packaging is now doing two jobs it may not have been designed for at once: surviving transit and serving as the arrival experience. Packaging designed for a shelf gets evaluated under lighting, next to competitors, at eye level. Packaging designed for a doorstep gets evaluated after a courier has handled it, possibly in rain, by someone who already bought the product.
Design for the doorstep. That means durability and finish that survives handling, and it means accepting that a scuffed premium box reads worse than a plain Amazon box would have. If your packaging is beautiful and delicate, SIPP will expose that.
Our unboxing and packaging playbook covers the design side of that arrival moment, and the SIPP constraint changes which of those ideas are available to you rather than removing the opportunity.

We do not sell packaging or testing services. Bring your catalog and we will help you find where the payback actually is.
Book A CallRunning The Numbers
Segment the catalog before doing any arithmetic, because three of the four groups have obvious answers and only one requires a calculation.
- Mandatory products. No calculation. Certify, or accept the consequences of non-compliance on a requirement rather than an option.
- Bulky products below the threshold. The packaging fee avoided is the dominant term and it usually swamps the test cost within weeks at any meaningful volume. Certify unless volume is negligible.
- Standard-size, high volume. Calculate. The discount plus removed prep steps plus materials savings against a one-time test, tested across every SKU in the family.
- Standard-size, low volume. Usually no. A few cents a unit on a few hundred units does not repay a lab test in a useful timeframe.
Two terms get systematically underweighted when brands run this. The removed prep step is worth real money now that prep is entirely your cost, and it recurs on every unit forever. And the packaging materials you stop buying are a cost removed rather than reduced, which most models never capture because they were sitting in a supplies line nobody attributed per SKU.
If your unit economics are not built at the SKU level yet, this calculation will be guesswork. Our landed cost guide and the FBA fee breakdown cover the structure this sits inside.
What SIPP Is Not
Three confusions worth clearing, because each one leads to a wasted decision.
It is not the Climate Pledge Friendly badge. Amazon's packaging FAQ states this directly. SIPP is not part of that program, and qualifying for the badge requires one of its own certifications. Sellers regularly assume packaging certification earns a sustainability badge on the listing. It does not.
It does not replace prep. SIPP addresses outbound packaging to the customer. Inbound labeling, palletization, and everything else in your prep workflow remain yours. Every unit still needs its FNSKU applied to an outer surface. Certification narrows the prep scope rather than eliminating it.
It is not permanent. Status is conditional on ongoing damage and compliance performance, so it is better understood as a standard you maintain than a certificate you earn.
Evolve Media Agency does not sell packaging design, lab testing, or prep services, so we have no stake in whether you certify. Every figure here is third-party reported except where attributed to Amazon's packaging FAQ, and fee structures change. Verify in Seller Central and the enrollment portal before committing to a testing spend.
A Decision Sequence
Work through this once per product family rather than per SKU.
- Check existing enrollment. If you were SIOC certified, you may already be enrolled and receiving benefits without knowing it.
- Pull the eligible ASIN list from Amazon and the ineligibility tab. Start from Amazon's assessment rather than your own.
- Sort into the four groups from section five. Mandatory, bulky, standard high volume, standard low volume.
- Identify product families that can share a test based on packaging format and size relationships. This is where the cost of certification actually gets decided.
- Assess packaging honestly against the standard before spending on a test. A package you suspect will barely pass should be strengthened first.
- Certify the mandatory and bulky groups. Calculate for standard high volume. Skip standard low volume.
- Update the prep workflow and confirm with whoever handles your inbound that certified units are no longer over-boxed.
- Watch damage-related returns for three months on newly enrolled SKUs, and revert or strengthen packaging if they move.
When To Skip This Entirely
If your catalog is standard-size, moderate volume, and your packaging is not currently designed to ship unprotected, the honest answer is often to do nothing. Testing costs money, redesigning packaging costs more, and a discount measured in cents on a few hundred units a month will not repay either. The urgency in this topic is real for bulky products and largely manufactured for everyone else.
The trigger to revisit is a packaging redesign you were doing anyway. Building the SIPP standard into a redesign already in progress costs almost nothing extra, whereas redesigning specifically to qualify rarely pays. If a new product is in development, specify the standard now. If your current packaging works and your products are not bulky, leave it.
What To Remember
- Non-enrolled small bulky and large bulky products incur a packaging fee from January 15, 2026 in the US, and from February 1, 2026 for EU oversize. Enrolled products are exempt.
- Certification is mandatory above a threshold. Per Amazon's packaging FAQ, packaging over 18 by 14 by 8 inches or weight over 20 pounds must be SIPP certified unless the product is in an excluded category.
- Two tiers exist. SIOC requires surviving the drop test sequence; Frustration-Free Packaging adds curbside recyclability and 120-second content removal, ruling out clamshells and loose fill.
- Reported discounts run $0.04 to $1.32 per unit for certified standard-size products, while reported bulky packaging fees vary by source between roughly $1.51 and $4.40, averaging about $2.07.
- Decertification is the real risk. Status is conditional on damage and compliance rates, and by the time it is removed you have already shipped damaged units and absorbed the reviews.
- The branding effect is positive, not negative. Certified products arrive in your retail packaging rather than a plain Amazon box, which is an improvement most coverage describes backwards.
- SIPP is not the Climate Pledge Friendly badge, and it does not replace prep. Every unit still needs an FNSKU applied to an outer surface.
Where This Came From
- Amazon, packaging program FAQ, for the January 15, 2026 US packaging fee start, the February 1, 2026 EU oversize date, the mandatory certification threshold above 18 by 14 by 8 inches or 20 pounds, excluded categories, the note that SIPP is not part of Climate Pledge Friendly, and the February 15, 2026 ineligibility tab.
- Amazon, Fulfillment by Amazon, for public program context.
- Industry reporting for the two-tier structure, the ISTA 6 drop test and 120-second openability requirements, the 6 by 4 by 0.375 inch minimum, the $0.04 to $1.32 discount range, the $300 to $2,000 lab testing range, group testing, five to seven business day review times, and automatic carryover of SIOC certifications. These are consistent across multiple sources but are not all confirmed on Amazon-owned pages.
- The reported decertification threshold, described as Amazon decertifying at 90 percent confidence that damage rate exceeds 5 percent or non-compliance exceeds 5 percent, comes from a single third-party source and is presented in the body as reported rather than confirmed.
- The bulky packaging fee amount is reported inconsistently across sources as $1.51 to $4.04, $1.51 to $4.40, and averaging about $2.07 per unit. Section 04 presents the disagreement rather than resolving it.
