Which form is used to accompany material purchased from a commercial source?

The use of DD Form 1155 is essential when it comes to documenting the purchase of material from a commercial source. This form serves as a solicitation and contract for commercial items, providing a legal framework for the acquisition process. It is typically used to initiate purchase orders for a wide range of goods and services, facilitating the transaction between the government and commercial vendors.

The significance of the DD Form 1155 lies in its function as a standardized document that outlines the specifics of the transaction, including the items being purchased, their quantities, prices, and terms of delivery. This ensures that both the purchasing agency and the vendor have a clear understanding of the agreement, promoting efficiency and transparency in the procurement process.

In contrast, the other forms mentioned have different purposes: DD Form 1348 is primarily used for receiving and shipping items within the military supply chain, DD Form 250 serves as a material inspection and receiving report for contractor deliveries, and DD Form 2016 is utilized for annual sales reporting by Federal agencies, which does not relate to direct purchases. This distinction emphasizes why the DD Form 1155 is the correct choice for documenting purchases from commercial sources.
