Currently, Poshmark does not support cross-border shipping on the platform. There are a handful of sellers currently shipping from international locations as part of a test program, which we are targeting to roll-out more broadly soon.
For sellers with overseas product, you are welcome to first ship it to a U.S. based destination (seller serves as the importer of record), and then to a Poshmark buyer. However, bear in mind that this prolonged shipping period may result in violation of our shipping time SLAs.
If you are interested in signing up for cross-border shipping opportunities, feel free to reach out to the Enterprise Support team for details.
