What document must be provided to show the contents of an international package?

A customs declaration is essential for any international package as it provides vital information regarding the contents of the package. This document specifies what items are being shipped, their value, and their purpose, which is necessary for customs authorities in the destination country to assess any applicable duties or taxes and ensure that the items comply with import regulations.

This declaration helps prevent complications during the customs clearance process, as it maintains transparency and provides a clear description of the contents. Without a customs declaration, packages may face delays, additional fees, or even rejection at customs.

The other documents mentioned serve different purposes: a shipping manifest outlines a list of items being transported, a waybill is essentially a contract between the shipper and carrier for transport, and a delivery receipt confirms the receipt of packages but does not detail their contents. While these documents are important in their contexts, they do not fulfill the requirement of disclosing the contents of an international shipment as accurately and comprehensively as a customs declaration does.
