Every summer, Amazon shuts down the meltable products for FBA access for heat-sensitive products. In 2026, 58,000 ASINs are flagged across Amazon US and Amazon Canada.
If yours is one of them, April 20th is your hard deadline.
Here is the Amazon meltable FBA 2026 timeline. FBA intake for flagged ASINs stops April 20th. Disposal of meltable inventory in Amazon’s network begins May 1st. FBA access reopens September 28th. That is five months without FBA if you have no plan.
The rule Amazon uses: if your product cannot survive 155°F inside a truck or trailer, it cannot stay in FBA during this window. That threshold applies to both Amazon US and Amazon Canada.
We get hundreds of inbound leads a month on this. Chocolates, gummies, protein bars, cosmetics, probiotics. The questions are always the same. What are my options? Can I keep the Prime badge? Here is how I walk through it.
Start Here: Pull the Meltable ASIN List First
The meltable ASIN list Amazon releases is your starting point. The flagging logic is not consistent. Some SKUs in a category get hit, others do not. Some gummies get flagged, others sail through. Cosmetics brands sometimes come out clean while protein bars get pulled.
Amazon updates the meltable ASIN list annually, typically by March 1st. If you have not checked it yet, do that now. If you sell on both Amazon US and Amazon Canada, check each marketplace separately. Being clear in one does not mean you are clear in the other. Contact us and we can share the list so you can cross-reference your catalog directly.
The Dispute Route: Worth It for Some, Not a Plan for Most
If your ASIN is flagged and you believe it should not be, you can dispute it. You need written confirmation from your manufacturer on letterhead confirming the product can withstand 155°F. That letter goes to Seller Support before April 20th. Amazon may also request physical samples for testing.
To request an Amazon meltable exemption, focus your case on specific product features that support heat resistance. General claims do not carry weight.
I will be honest: most products that get flagged stay flagged. Chocolates and gummies that genuinely melt are not getting through. If your product should not be on that list, file it. Just do not treat it as your only plan.
SFP Keeps the Badge. The Math Is the Hard Part.
Seller fulfilled prime for cold chain products is real. A lot of people say they can run it. It is genuinely difficult. We are one of the only operations in the US doing it at scale.
The Coverage Requirements Most Brands Underestimate
To meet Amazon’s SFP requirements, 30% of orders need to arrive in one day and 70% within two days. For cold chain fulfillment, that means overnight shipping on a portion of every order. FedEx 2-day and overnight run $14 to $20 per shipment.
Add pick and pack, cold liner, ice packs, and inbound. You are looking at $20 to $22 all in. The realistic MSRP floor for SFP to work is $40 to $50. At $25 or $30, the math does not hold.
When Bundling Changes the Equation
A 2-pack or 3-pack that pushes AOV to $44 or $48 changes things entirely. We have a client running a 24-count protein bar case at $80 AOV. That is a completely different SFP conversation than a $39 single unit.
What Canadian Brands Need to Know
For Canadian brands selling on Amazon US, SFP requires US-based fulfillment. Cross-border distances make overnight shipping almost unavoidable, which wipes the margin. The better play is domestic FBM meltable fulfillment in Canada paired with a US 3PL for cross-border orders.
FBM Will Cost You the Badge. Here Is What That Is Actually Worth.
FBM meltable fulfillment is the most realistic path for most brands during this meltable season.
The Cost Difference Between FBM and SFP
All-in via Amazon Shipping or similar carriers runs $6 to $8 per order. That is the number I put against the $20-plus SFP model every time a brand is trying to decide between the two.
Cold Chain FBM: Getting the Delivery Window Right
Three to four days is the target to keep ice packs effective. USPS Priority works well. DHL eCommerce typically does not. For Canadian brands fulfilling domestically, shorter transit distances work in your favor. A single well-positioned Canadian 3PL can often cover most of your customer base within that window.
What Losing the Prime Badge Actually Costs You
Dropping to FBM typically drives a 30 to 70% drop in order velocity. For brands where Amazon is one channel among several, five months of FBM is manageable. For brands built entirely around FBA velocity, run that number before you default to FBM without a strategy.
Three Questions I Ask Before Recommending Anything
Every catalog is different. Here is how I work through the decision with every brand that comes to us during this restriction period.
Can You Dispute the Flag Before April 20th?
If you have manufacturer documentation confirming your product survives 155°F, file the dispute now. Do not wait. The deadline does not move.
Does Your MSRP Support SFP?
If your MSRP is above $40, or if bundling can get you there, SFP is worth modeling. Let us run the numbers against your actual order volume and catalog before you rule it out.
What Does Losing the Prime Badge Cost You in Velocity?
Run that number against your category data before treating FBM as the easy default. For some brands it is a manageable hit. For others it is the decision that defines how the next five months go.
Conclusion
Every catalog is different. A $39 single unit and an $80 case pack face completely different math. We built a full playbook that walks through the dispute process, the SFP cost model, and cold chain FBM setup for your specific catalog and market. Download the AMZ Prep Meltable Season Playbook here.

Frequently Asked Questions
What products are considered meltable by Amazon?
Amazon classifies any heat-sensitive consumable product that risks degrading at 155°F as meltable. This includes chocolate, gummies, select wax-based products, certain cosmetics, and some supplements like probiotics.
When does meltable season in Amazon start in 2026?
FBA intake for meltable ASINs stops April 20th, 2026. Disposal of remaining meltable inventory begins May 1st. FBA access reopens September 28th.
Does the Amazon meltable policy apply to Amazon Canada?
Yes. The same 155°F threshold and seasonal restriction window applies to Amazon Canada as it does to Amazon US. Sellers on both marketplaces need to check their meltable ASIN list for each separately.
Can I still sell meltable products during the restricted period?
Yes. You can continue selling via FBM or seller fulfilled prime during the restriction window, provided you can maintain cold chain integrity during storage and transit.
What is the minimum MSRP for a seller fulfilled prime cold chain to make sense?
Based on the all-in fulfillment costs for cold chain SFP, a minimum MSRP of $40 to $50 is the realistic floor. Below that, overnight shipping and cold chain costs typically exceed the margin available.
What happens if I do not remove meltable inventory before April 20th?
Any meltable inventory remaining in Amazon’s fulfillment centers after April 20th may be marked unfulfillable. Disposal begins May 1st and Amazon charges a per-unit disposal fee.
