The systems and methods described herein relate generally to the integration of a shipping label with a customs form to provide a single label having postage, addressing, customs, and other information for international shipping, and in particular, to managing landed cost and harmonization for international packages. In one embodiment, managing the landed cost and harmonization may comprise generating a unique self-validating postage indicium or mark in response to a request that includes a description of contents for a package onto which an international shipping label is to be placed and a destination country where the package is to be delivered. As such, the unique self-validating postage indicium or mark may indicate that landed costs for delivering the package to the destination country have been pre-paid, wherein the unique self-validating postage indicium or mark and a customs declaration form may be printed on the international shipping label.
The present invention is generally directed to online postage services and systems that have an online connection, and more particularly to systems and methods for enabling a shipping label service to be integrated with a third party application or website. One preferred embodiment includes a computer program product having a computer-usable medium with a sequence of instructions, which when executed by a processor, causes the processor to execute a process that provides an online postage and shipping label service. The computer program product is configured to be integrated into a third party application, and the process includes the steps of enabling a user of the third party application to purchase postage, and enabling a user to generate one or more images of one or more shipping labels via the third party application.
