Packaging materials type

Question

I want to make certain that I am following the eBay policies for shipping and packaging and that I absolutely CAN use USPS-branded boxes — but only if:

You ship via the matching USPS service
Example:
- Priority Mail box → must ship Priority Mail
- Priority Mail Express box → must ship Express
- Flat Rate box → must use Flat Rate pricing

I cannot mix:

❌ USPS Priority box + First-Class / Ground Advantage label
❌ USPS box + UPS or FedEx label

If you do, USPS can:

Upcharge you
Or return the package

Your assertions are correct. I would add on the flat rate boxes that you must use the corresponding flat rate pricing - a medium flat rate box needs a medium flat rate label, etc.

I don’t know that ups or fedex would really care if you reuse a usps box, as long as you take it to the correct carrier, but I would avoid it. USPS materials are meant for use with usps services only.
