Amazon Restock Limits Are Back: What It Means for Resellers (and Why Walmart Just Got More Attractive)

They’re back. And this time, they’re more specific. More confusing. And potentially more damaging if you don’t adapt quickly.

If you’ve been selling on Amazon long enough, you already know how disruptive restock limits can be.

They’re back. And this time, they’re more specific. More confusing. And potentially more damaging if you don’t adapt quickly.

What’s Happening

Sellers started noticing the restrictions around April 8, 2025. Amazon hasn’t made a formal announcement, but the rollout is already affecting shipments.

You might see errors like:

• “You already have high days of supply for this ASIN…”

• “This product has a maximum inventory level and exceeds the allowed quantity…”

  
  

There’s no clear definition of how those inventory levels are calculated. And even if you’re out of stock, Amazon might still block you from sending more inventory in.

Why It Matters

This isn’t just a policy change. It’s a shift in how Amazon wants sellers to operate.

Amazon is pushing for leaner FBA inventory. No more than 90 days of supply, according to what we’ve seen.

That’s fine in theory. But if you just ran a promo or got picked up by a TikTok influencer, your “90-day supply” number might look inflated—even if you’re about to stock out.

Worse, these new limits apply both at the seller level and the ASIN level. If another seller over-stocks an ASIN, you might get blocked from sending any in. Even if your inventory is at zero.

The Data is Broken

Amazon’s “Days of Supply” is a lagging metric. It doesn’t update in real time. It doesn’t factor in your lead times. And it often contradicts itself. You can get flagged for both “low stock” and “overstock” on the same SKU.

This makes planning nearly impossible. And it puts resellers—especially wholesale sellers—at a disadvantage.

So What Can You Do?

Here’s what we’re telling our users:

1. Monitor Inventory Velocity Closely

Track your sell-through rate daily. Don’t wait for Amazon’s metrics to catch up.

2. Don’t Rely on FBA Alone

If you’re not already using 3PLs or storing some inventory FBM, it’s time to start.

3. Diversify to Walmart

This is big: Walmart’s WFS program isn’t hitting sellers with the same inventory restrictions.

Sellers are already moving more of their catalog to Walmart Marketplace because of this.

We’ve seen a 14% uptick in Walmart repricing demand on Flashpricer just in the last two weeks.

It makes sense.

If Amazon’s going to throttle your FBA shipments, then leaning harder into WFS—where you can still keep inventory moving—is a smart play.

4. Automate Repricing to Maximize Limited Inventory

If you’re only allowed to send 300 units of your top seller, you need to make every sale count.

Flashpricer can help you win the Buy Box at the highest possible price, with real-time price updates across both Amazon and Walmart.

That means more margin per unit—and more control over your restock window.

What About AWD?

Don’t count on Amazon Warehousing & Distribution (AWD) to save you. Sellers are reporting that AWD transfers to FBA are being blocked too.

And even if it works, transfers take weeks. You could be out of stock long before anything lands in an FC.

AWD’s smart replenishment algorithms have also been inconsistent. You might still get stuck with low inventory fees and be unable to restock.

Seasonal Sellers: You’re in Trouble Too

Amazon says it “considers” seasonality. But in practice, sellers are still getting blocked—even when ramping up for known peak periods. If you’re selling meltables or Q4-heavy items, this is a huge problem.

Plan your inbound strategy now.

Build a case with your historical sales data.

Start the appeal process before your season hits.

Final Take

Amazon’s playing defense. That means more friction for you.

You can’t control the algorithm. But you can control how fast you react.

Stay lean. Stay automated. Stay diversified.

If you’re not already repricing across Amazon and Walmart with tools like Flashpricer, you’re going to fall behind the sellers who are.

This isn’t just a warehouse problem. It’s an operations problem.

And repricing is where you take back control.
