Every year, as temperatures start climbing across the United States, Amazon quietly enforces a policy that catches many sellers off guard. If your products are heat-sensitive, you can’t simply send them into Fulfillment by Amazon and expect them to sit safely in a warehouse all summer.
Amazon’s meltable inventory rule limits when certain products can be stored or fulfilled through Fulfillment by Amazon. And if sellers don’t plan ahead, the result can be stranded inventory, unexpected disposal fees, or products that suddenly become unsellable.
For sellers operating in grocery, candy, supplements, cosmetics, or any category involving heat-sensitive items, this is one policy you absolutely need to understand.
Why Amazon Restricts Meltable Products
Amazon defines meltable inventory as any product that can melt when exposed to temperatures of about 155°F during shipping or warehouse storage. Common examples include chocolate, gummies, jelly-based items, and some wax-based products.
From Amazon’s perspective, the restriction is about protecting customer experience. If a product arrives melted, damaged, or unusable, it leads to returns, negative reviews, and refunds.
Instead of taking that risk, Amazon simply pauses FBA storage and fulfillment for meltable products during the hottest months of the year.
The policy isn’t new, but it continues to surprise sellers who don’t build their inventory planning around it.
The Critical Dates Sellers Need to Know
Each year Amazon enforces a seasonal cutoff window for meltable inventory stored through FBA.
For example, in the most recent cycle Amazon announced that it would not accept meltable inventory between April 15 and October 15 at its fulfillment centers.
That means two things for sellers:
First, you cannot send new meltable products into FBA during that period.
Second, any meltable inventory still sitting in Amazon warehouses after the cutoff may be marked unfulfillable and removed or disposed of.
If sellers fail to act, Amazon may dispose of the inventory beginning shortly after the deadline, often with a disposal fee attached.
In other words, waiting too long can turn sellable inventory into an unexpected cost.
What Happens to Meltable Inventory After the Deadline
Once the cutoff date arrives, Amazon begins flagging meltable ASINs inside Amazon Seller Central.
Products may be classified as “unfulfillable,” meaning they cannot be shipped to customers through FBA during the restricted months.
At that point sellers usually have three options:
- Remove the inventory from Amazon’s warehouses
- Allow Amazon to dispose of the inventory for a fee
- Switch fulfillment methods if possible
For many sellers, the safest move is to create a removal order before the deadline so inventory can be stored elsewhere until cooler weather returns.
The Inventory Strategy Most Sellers Miss
Where many sellers make mistakes is treating the meltable policy as a last-minute logistics problem.
In reality, it’s an inventory planning problem.
If you sell meltable products, your entire supply chain should be built around the April deadline. That means forecasting sales so inventory sells through before the cutoff rather than sitting in warehouses.
Smart sellers often reduce inbound shipments in late winter and early spring to avoid getting stuck with leftover stock.
Others switch temporarily to merchant-fulfilled orders during the summer months, shipping products themselves instead of relying on FBA.
Either way, ignoring the policy can quickly create operational headaches.
Why This Matters for Growing Brands
The meltable inventory restriction might seem like a small operational rule, but for certain categories it can have a major impact.
Brands selling chocolate, candy, health supplements, cosmetics, or other temperature-sensitive goods rely heavily on careful inventory timing.
If those products suddenly become unfulfillable in FBA, sales can stop overnight.
That’s why experienced sellers treat this policy as part of their yearly operational calendar. It’s not just about compliance. It’s about protecting revenue and maintaining inventory flow during the busiest ecommerce months.
Final Thoughts
Amazon’s meltable inventory rule is a reminder that selling through FBA requires more than just listing products and sending shipments.
Seasonal logistics policies, inventory deadlines, and fulfillment restrictions all play a role in how your business operates.
For sellers working with heat-sensitive products, planning ahead is essential. If you know the cutoff dates, manage your inventory carefully, and build alternative fulfillment strategies, the meltable inventory rule becomes manageable.
Ignore it, and you may find your products literally melting into lost revenue.
