Which of the following is not a component of an international shipping label?

The correct choice identifies that shipping method details are not a typical component of an international shipping label. International shipping labels primarily require essential information that ensures the package can be accurately delivered and tracked across borders.

Sender and recipient addresses are crucial as they show where the package is coming from and where it needs to go. Tracking information is equally important, as it allows both the sender and the recipient to monitor the package's journey through different logistics networks. Customs declaration is necessary for international shipments to clear through customs, detailing what is inside the package and any applicable duties or taxes.

In contrast, the shipping method pertains to the specific service or priority level chosen for shipping (like express, standard, or economy), which is typically found in the shipping documentation rather than on the label itself. Thus, shipping method details are not required on the international shipping label itself, making it the correct choice in this context.
