What documentation is required to ship customer material?

The correct documentation required to ship customer material is the DD Form 1149. This form, known as the Requisition and Invoice/Shipping Document, is crucial as it serves multiple purposes in logistics, including requisitioning, shipping, and as an invoice. It provides an official record of the item being shipped, ensuring there is clear communication regarding the contents, quantity, and destination of the shipment. The use of DD Form 1149 facilitates efficient processing and tracking of materials through the supply chain, making it indispensable for both the shipper and the recipient.

Other forms mentioned, such as the DD Form 1348-1A, while also used in shipping, are not specifically designed for customer material shipments in the same comprehensive manner as the DD Form 1149. SF 145 and NAVSEA 1221 have specific applications within different contexts but do not serve as the primary documentation for shipping customer material. Thus, the DD Form 1149 is the preferred form for this purpose in the U.S. Navy logistics framework.
