Which of the following items cannot be shipped via PMEI?

The item that cannot be shipped via PMEI (Priority Mail Express International) is coins, banknotes, and jewelry. This restriction is primarily due to the high value and potential for loss or theft associated with such items. Shipping regulations often impose stricter guidelines on precious materials or currency to safeguard against the risks involved in international shipping.

For example, mailing cash or valuable items like coins and jewelry poses significant security challenges, and carriers frequently discourage or outright prohibit the shipment of these items to reduce liability. On the other hand, electronics, documents, and clothing can be shipped as they typically fall within the accepted and regulated categories for international mail.
