Please note that this guidance is for international freight and fulfillment.
Maximum Box and SKUs Size
All boxes inbounded into our network must meet the following dimensional requirements. Boxes greater than these dimensions present a safety hazard to receiving teams. This applies to all SKUs and boxes shipped whether by small parcel delivery, LTL (less than truckload), or FTL (full truckload) carrier.
- Longest side = 40" or less
- Median side = 30" or less
- Shortest side = 30" or less
- Gravitational weight = 50 lbs or less
Ship in Own Container (SIOC)
Items over 20 lbs or do not fit into a box that is 18" x 14" x 8" (oversized items) need to be sent in ready-to-ship. These are the maximum requirements for one SKU to be shipped using our supplied containers.
If they exceed these dimensions, they must be shipped using a merchant's own customer container (SIOC), which must follow the maximum dimensions listed above in the “Maximum Box and SKUs Size” section. This means we will not place these items in another box or envelope.
Additionally, at a minimum, the SIOC product needs to be able to fit a 4x6 shipping label.
Flexport also restricts certain products - please double-check this list so that you are in compliance with our guidelines. Failure to follow these requirements will result in non-compliance fees and the potential removal of your inventory.
Shipping Method Restrictions
When using Flexport rates, there are sizing restrictions for the various methods.
If your shipment is greater than 250lbs, you are recommended to use Freight instead of Small Parcel Delivery. This will also be cheaper for you to inbound.
International Shipping Dimension Requirements
There are additional separate requirements for shipping to Canada or other international countries.
Products shipping to Canada must meet the following requirements:
- Longest side = 40" or less
- Median side = 24" or less
- Shortest side = 15" or less
- Gravitational weight = 50 lbs or less
- Dimensional weight (length * width * height/166) = 50 lbs or less
Products shipping internationally to any other country (except Canada) must meet the following requirements):
- Longest side = 40" or less
- Median side = 24" or less
- Shortest side = 15" or less
- Gravitational weight = 44 lbs or less
- Dimensional weight (length * width * height/166) = 44 lbs or less
