We do not support region to region transfers at this time. Metals purchased in one region can only be stored in that region; however, you can take delivery from any region with minimal restrictions.
For example, if you buy bars for storage in Zurich, you must store them in Zurich until you sell or have them shipped to your address of record (and you may change your address of record if you'd like to take delivery at a different location, including an overseas location). You cannot buy bars in Zurich and have them shipped to London for storage.
