I have of late been getting seriously over billed when I use Fedex Pak poly bag to ship things, they get the dimensions totally out, which hasn't always been the case. I end up getting billed on dimensions that are much bigger than the package inside the Fedex Pak poly bag and hence get billed 3 to 4 times what I should be. My Fedex account manager applies a credit after investigating but maybe I could do something differently to prevent it happening in the first place because its a pita to resolved. I use Fedex Pak poly bag for lightweight lower value items especially when shipping internationally because it offers cheaper rates than shipping in your own packaging.

Any help would be appreciated.

This is all I can find on the Fedex website regarding Fedex Pak poly bag:

FedEx Pak shipments exceeding 2.5kg will be charged at FedEx International Priority rates. ** Dimensional-weight pricing is applicable for FedEx Pak shipments exceeding 940 cubic inches or 15,400 cubic centimeters in volume.

EDIT : By Fedex Pak in terms of this post I mean the Large poly bags, the soft plastic bag mailers, I have updated the post to clarify that.

Apologies for a dumb question, but can't seem to confirm this anywhere:

Are there minimum dimensions for a self-packaged FedEx shipment? In other words, what's the smallest box they'll accept (using a prepaid label from vendor, if that matters)? Maybe no practical "lower limit", but wanted to confirm before packing up the item.

TIA!

Hi. I'm a business owner and do most of my shipments through the USPS. I'm looking to expand into FedEx Express 2Day and have some questions about the FedEx supplied packaging materials.

The first Google result for "fedex dimensional weight" is this site (yes I'm aware it is for FedEx india, but it is still the first result in the US). It states:

FedEx Express packaging offers you a practical and advantageous solution. Dimensional weight standards are not applied to this packaging, providing that the dimensions have not been changed.

Further, in the service guide is the following line:

FedEx Express applies dimensional weight to all shipments in customer packaging and may apply it to shipments in FedEx packaging.

So, question #1: Does dimensional weight apply to shipments using unmodified FedEx Express packaging materials?

If the answer is yes, question #2: Is it fine to modify FedEx Express packaging to lower the dimensional weight?

If the answer is no to question #1, question #3: What are the exceptions that do trigger dimensional weight to apply?

For example, on another FedEx page the following statement is made:

Dimensional-weight pricing is applicable for FedEx Pak shipments exceeding 940 cubic inches in volume.

Thanks for your time.
