Amazon Restock Limits 2025: How to Stay in Stock and Boost FBA Profits

📦 Amazon just reintroduced restock limits—and it’s already disrupting FBA operations for sellers across the board. Here’s what’s changing, how it affects your business, and what you can do to stay in control with Seller Labs.

🚨 What’s Going On?

In April 2025, Amazon quietly reactivated restock limits for FBA sellers, capping how much inventory you can send in per ASIN. Many sellers report restrictions tied to 90 days of supply, with no official announcement on Seller Central.

This shift isn’t hypothetical—it’s already live.

👉 On Amazon’s Seller Forums, sellers across multiple categories confirm that capacity limits have been reinstated, tightening how they prep for Prime Day and mid-year spikes.

“We were cut to where we now only have about 30% of the storage space that we were given for April.”

📉 Why This Affects More Sellers Than You Think

If you rely on FBA, this change can put serious pressure on your margins and performance.

Sellers are now facing:

• ❌ Stockouts on high-performing SKUs
• 📉 Lost organic rank due to slowed sales velocity
• 🚚 Higher emergency shipping or 3PL costs
• ⚠️ Inability to meet demand during Prime Day, summer promos, and more

And with tariffs rising, supplier lead times tightening, and sales windows shifting, you can’t afford inventory surprises.

🧠 What Amazon Recommends

An Amazon representative shared the following advice on the Seller Forums:

✅ “Make sure you are addressing excess or unhealthy inventory to free up more capacity for faster-selling products.”

✅ “Use the Capacity Manager to request more capacity in FBA.”

✅ “Consider Amazon Warehousing and Distribution if you need longer-term storage.”

While these are helpful tips, sellers need real-time data and actionable tools to implement them effectively.
