🧭 Overview
When creating a shipment, each box is assigned a specific set of items and quantities, known as box content.
Once this is submitted and labels are generated, Amazon expects that:
👉 Each physical box matches exactly what was declared in the system
📦 How Box Content Works
Each box has:
A defined list of items (SKUs)
Exact quantities per item
A unique box label tied to that content
👉 This means every label corresponds to a specific box with specific contents
⚠️ Why You Shouldn’t Switch Items Between Boxes
❗ 1. Mismatched Box Content
If you move items between boxes:
The actual contents no longer match what was submitted
Amazon’s system detects inconsistencies
❗ 2. Receiving Errors
When Amazon processes your shipment, they may flag:
“Additional quantities encountered”
Missing items
Incorrect box contents
❗ 3. Delays in Processing
Incorrect box content can cause:
Slower check-in times
Manual inspection of your shipment
❗ 4. Inventory Discrepancies
You may experience:
Missing inventory
Incorrect item counts in your account
❗ 5. Possible Fees or Warnings
Repeated mismatches may lead to:
Compliance warnings
Additional handling or processing fees
✅ What You Should Do Instead
✔ Adjust Before Finalizing
Edit your box content in the system
Rebalance items between boxes
Ensure each box meets weight limits
Then generate labels
✔ Update and Reprint Labels
If changes are needed after setup:
Update the box content first
Reprint the correct labels
Pack boxes according to the updated content
🚫 What to Avoid
Do not swap items between labeled boxes
Do not pack boxes differently from what was entered
Do not ignore weight limits without updating box content
💡 Tip
👉 Accuracy per box is critical—not just total shipment accuracy
✅ Quick Summary
