If Amazon requires box content information for your shipment workflow, you should still provide box content even if you are only shipping one box.
Why Is Box Content Still Needed?
Box content tells Amazon:
Which items are inside the box
The quantity of each item
How inventory is organized within the shipment
Whether you send one box or one hundred boxes, Amazon still needs to know what inventory is arriving.
What Happens If You Only Have One Box?
The process is actually simpler because:
All inventory is assigned to a single box
There is only one set of box dimensions and weight to enter
No inventory needs to be split between multiple boxes
You will still provide:
Box dimensions
Box weight
The contents of the box
Are There Any Exceptions?
Amazon's requirements can vary depending on:
Marketplace (US, UK, CA, etc.)
Shipment workflow
Shipment type
Seller account settings
In some cases, Amazon may allow alternative methods of providing box content information, but if box content is requested during shipment creation, it should be completed even for a single box shipment.
