Why Is My Shipment Prohibited

Shipping Safety

When it comes to sending and receiving mail, safety is always our number one priority. We owe it to our Kaeboxer’s to protect them from dangerous items or legal repercussions. Operating as a same day delivery service comes with guidelines imposed by the United States government. In order to securely fulfill mail shipments, all same day delivery services must abide by these laws and regulations.

There are many reasons an item is rejected from entering the mail stream. For example, sending a homemade dish to a relative across the country sounds like a lovely way to show appreciation for family. Depending on the estimated time spent in transit the item could spoil before it even reaches the destination. While you may feel confident that you safely packaged the compressed air can, batteries, fireworks, or any other item that has the potential to spontaneously combust, we cannot take that chance. Ensuring the safety of every single courier that fulfills a same day delivery service request is a responsibility that we do not take lightly.

Please consider the potential harm a dangerous item poses to the Kaeboxer or the employees fulfilling the shipment at the post office. Items are prohibited from shipping to keep us all safe. Not only does this help avoid unintentional injury or accidents, we also owe it to our Kaeboxer’s to keep them out of legal trouble. Sending a same day delivery service shipment with illegal goods in it will put your courier at risk for a crime they did not knowingly commit. Keep this in mind while considering placing an order for a same day delivery service for a prohibited item.

To ensure your same day delivery service is completed without issue, check our list of prohibited items prior to fulfilling your shipment. If you believe a shipment was fulfilled which contained items from this list, please contact Kaebox directly at so we may conduct a thorough investigation.
