In the evolving landscape of Amazon FBA, sellers are facing new challenges with inventory restrictions that operate at the ASIN level across all sellers. This article explores how these restrictions work and provides a step-by-step guide on using Tactical Arbitrage‘s Tactical Edge feature to navigate these limitations effectively.

How Amazon’s ASIN-level restrictions work

Amazon recently shared that they now evaluate inventory levels for each ASIN collectively across all sellers in their fulfillment network. This means:

  • Days of supply calculations occur at the ASIN level, not at the individual seller level
  • When one seller sends large quantities of a product, it can restrict other sellers’ ability to send in the same item
  • Total inventory levels for each ASIN across Amazon’s entire fulfillment network determine restock limits
  • Even if you’ve never sent in a particular product before, you might face restrictions if other sellers have already stocked significant quantities

Why this matters for sellers

These restrictions create a new competitive dynamic where understanding the current inventory landscape is essential before making purchasing decisions. Without visibility into total FBA inventory levels across all sellers for an ASIN, you risk:

  • Buying inventory you cannot send to FBA
  • Missing opportunities when inventory levels are low
  • Poor inventory planning and cash flow management

Using Tactical Edge to navigate inventory restrictions

Tactical Arbitrage’s Tactical Edge feature provides the units of inventory that every seller has on a given ASIN. This helps sellers make informed decisions in this new environment. Here’s how to use it effectively:

Step 1: Access Tactical Edge

  • Log in to your Seller 365 account
  • Navigate to Tactical Arbitrage
  • Open “Analysis Tools” in the left navigation menu, then select “Tactical Edge”
Tactical Edge under Analysis Tools in the left menu of Tactical Arbitrage

Step 2: Set up your parameters

  • Enter the ASIN you want to research, along with its buy price and shipping cost
  • Select the countries you want to research
Tactical Edge parameters

Step 3: Analyze inventory insights

  • Review the “FBA Total Stock” metric to see current inventory levels across all sellers

Step 4: Evaluate restock potential

  • Compare current inventory levels against Amazon’s typical thresholds
  • Look for products with lower inventory levels relative to sales velocity
  • Identify ASINs where you have a higher probability of sending in inventory

Step 5: Make data-driven decisions

  • Prioritize products with favorable inventory-to-sales ratios
  • Consider timing your purchases when inventory levels are decreasing
  • Avoid products where inventory levels are already high across all sellers

Best practices for managing inventory restrictions

  • Monitor your restock limits regularly through Seller Central
  • Create a systematic process for checking inventory levels before making purchasing decisions
  • Diversify your product portfolio to reduce risk from any single ASIN restriction
  • Consider smaller, more frequent inventory shipments to maintain sending ability
  • Build relationships with suppliers who can hold inventory if necessary

Conclusion

Amazon’s ASIN-level inventory restrictions have fundamentally changed how sellers must approach inventory planning. By leveraging tools like Tactical Arbitrage’s Tactical Edge feature, sellers can gain crucial visibility into the total FBA inventory landscape, making more informed sourcing decisions and maintaining a competitive edge in the marketplace.

Remember that staying informed about inventory levels across all sellers for your target ASINs is now not just advantageous but essential for sustainable success on Amazon FBA.​​​​​​​​​​​​​​​​
