While cross-listing items to eBay, you may encounter an error like the one shown above stating that the package weight is invalid or missing. This happens when eBay does not have enough shipping information for the item, which is required to calculate shipping costs and delivery options.
Why this happens
This error usually occurs because:
The product data pulled from Amazon does not include weight or dimensions
eBay requires valid shipping details before allowing the listing to be published
The item may not have complete catalog data available through the eBay API
How to fix it
You have two options to resolve this:
✅ Option 1: Add the details manually (recommended)
In the listing window, scroll to Update Product Dimensions
Click the checkbox or section to enable it
Select Use Package Dimensions (Recommended)
Enter the following:
Weight (required)
Dimensions (Length, Width, Height)
Package Type (e.g., Letter, Box, etc.)
Save and proceed with listing
This is the quickest and most reliable way to fix the issue.
🛠 Option 2: Contact eBay Support
You can reach out to eBay and request that they update the missing product data in their catalog. If they add it, the information may automatically populate in AccelerList in the future.
💡 Tips
Always enter accurate weight and dimensions to avoid shipping issues or additional charges
Even if optional, adding dimensions helps prevent future listing errors
Books and media items typically use small package types like Letter or Parcel
One-line summary
This error occurs when eBay is missing required shipping details, and it can be fixed by manually adding the item’s weight and dimensions during listing.
