What type of warehouse is used for storing goods until their introduction into the U.S.?

A bonded warehouse is specifically designed to store goods that are imported into the United States until the customs duties are paid or until the goods are ready for distribution into the domestic market. These facilities are operated under customs supervision, which means that goods can be stored for an extended period without the payment of duties until they are officially cleared.

The purpose of a bonded warehouse is to facilitate trade while ensuring compliance with customs regulations. This allows importers to manage their cash flow better, as they do not need to pay duties on their goods until they are ready to move those goods into the U.S. market. In addition, these warehouses enhance the security of the goods stored within them since they are subject to specific regulations and oversight.

In contrast, distribution centers focus on the logistics of moving products through to retailers and consumers, and overseas warehouses primarily serve to store goods before they are shipped internationally. Public storage units are typically used for personal storage rather than commercial purposes. Thus, the nature and function of a bonded warehouse distinguish it as the correct answer in this context.
