Import-export clerks manage data for international shipments and provide support for many steps of the transportation process. They work with customs agents, warehouse staff, shipping companies, and clients. Clerks help with shipping, receiving, and record keeping for international transactions. Most of their working day is spent in an office atmosphere as they verify that all documentation adheres to import-export policies and laws. Entry-level positions are available to those with a high school diploma, although applicants with international trade experience are generally favored by employers.
