Amazon's Meltable Inventory Policy: What FBA Sellers Need to Know About Heat-Sensitive Products
Amazon's meltable inventory policy restricts FBA shipments of heat-sensitive products like chocolate, gummies, and wax items during warm months. Sellers must plan inventory and fulfillment strategies around the seasonal blackout window to avoid lost sales.
Overview
Amazon enforces a seasonal meltable inventory policy that restricts when certain heat-sensitive products can be sent to and stored in Fulfillment by Amazon (FBA) warehouses. This policy exists to protect product quality during warmer months when temperatures in transit and storage facilities can cause items like chocolate, gummies, and wax-based products to degrade. Understanding these restrictions is essential for FBA sellers who deal in consumables, cosmetics, or any temperature-sensitive goods.
Key Points / What Sellers Need to Know
- Seasonal restriction window — Amazon typically enforts meltable product restrictions from approximately mid-April through mid-October each year, though exact dates may shift and sellers should check Seller Central for the current year's window.
- Affected product types — Items classified as meltable include chocolate, chocolate-containing products, gummy vitamins and supplements, certain confections, wax-based products, and other items that lose structural integrity or quality when exposed to sustained high temperatures.
- Inbound shipment blocks — During the restricted period, Amazon will not accept inbound FBA shipments of products flagged as meltable. Sellers cannot create new shipments for these ASINs during the blackout window.
- Active inventory handling — Meltable inventory already stored in FBA warehouses before the cutoff date may remain available for sale, but Amazon may suppress listings or add warnings if product quality cannot be guaranteed.
- ASIN-level classification — Amazon determines meltable status at the ASIN level. Even if you believe your product can withstand heat, if Amazon has classified it as meltable, the restrictions apply regardless of your packaging or formulation.
- No opt-out mechanism — Sellers cannot override or appeal the meltable classification through standard channels. The classification is based on product category and attributes in Amazon's catalog.
How the Meltable Policy Works
Amazon's meltable policy operates on a defined calendar window each year. Before the restricted season begins, sellers receive notifications through Seller Central advising them of the upcoming cutoff date for inbound shipments of meltable products. Once the restriction period starts, FBA will reject any new shipment plans that contain ASINs flagged as meltable. Products that were already received and stowed in fulfillment centers before the cutoff may continue to be sold, but Amazon reserves the right to limit fulfillment if warehouse temperatures exceed safe thresholds. When the restriction period ends in the fall, sellers can resume sending meltable inventory to FBA as normal.
Analysis & Recommendations
Why This Matters
Sellers dealing in chocolate, supplements, cosmetics, or other heat-sensitive products must understand this seasonal restriction to avoid shipment rejections and lost revenue during the summer months. Failing to plan ahead can mean months without FBA availability for key ASINs.
Key Takeaways
- Amazon blocks inbound FBA shipments of meltable products during a seasonal window typically spanning mid-April through mid-October
- Products are classified as meltable at the ASIN level based on catalog data, and sellers cannot opt out of the classification
- Sellers should build up meltable FBA inventory before the cutoff or prepare FBM fulfillment as a backup
- The policy affects chocolate, gummy products, wax-based items, and other heat-sensitive goods across multiple categories
Recommended Actions
- →Review your catalog now to identify which ASINs Amazon classifies as meltable, and plan inbound shipments before the spring cutoff
- →Set up FBM listings for meltable products as a backup fulfillment method during the restricted summer period
- →Monitor Seller Central announcements each year for the exact meltable restriction dates, as they may shift slightly from year to year
