why is my package stuck in customs A package can get stuck in customs for several reasons, including incomplete or incorrect documentation, customs duties or taxes that haven’t been paid, or an issue with the declared value of the item. Customs agencies inspect and clear shipments before they enter a country, and any discrepancies can delay the process. If your package is stuck in customs, it’s important to check the tracking information and contact the shipping carrier or customs office for updates on the status of your package.
