When creating an FBA shipment, Amazon may divide your inventory into multiple packing groups. This is a normal part of Amazon’s shipment workflow and helps organize inventory based on how it needs to be processed.
📦 What are Packing Groups?
Packing groups are categories Amazon creates to organize items within a shipment.
Each group may contain items with:
Similar handling requirements
Similar destination rules
Similar packaging or prep requirements
👉 Amazon uses these groups to streamline inbound processing.
🔍 Common Reasons for Multiple Packing Groups
1. Different Product Sizes
Amazon may separate:
Standard-size items
Oversized items
👉 These often require different handling and warehouse routing.
🏷️ 2. Different Prep Requirements
Items needing different prep may be grouped separately, such as:
Poly bagging
Bubble wrapping
Labeling requirements
⚠️ 3. Hazmat or Restricted Products
Hazmat or special-category products may require:
Specialized warehouses
Separate handling procedures
👉 These are commonly placed into separate packing groups.
📍 4. Different Warehouse Destinations
If Amazon creates a split shipment:
Each destination may generate its own packing group
👉 This is one of the most common reasons.
⚙️ 5. Inventory Type Differences
Amazon may separate items based on:
Product category
Fulfillment requirements
Seller settings
💡 Why Amazon Uses Packing Groups
Packing groups help Amazon:
Process shipments more efficiently
Reduce inbound errors
Route inventory correctly
Speed up receiving and fulfillment
⚠️ Important Notes
Multiple packing groups are normal
They do not always mean there are multiple warehouse destinations
Each group may require separate box content and labels
