7-11 REVIEW 1 QUESTIONS Q1. What is an NSN? Q2. What is the Afloat Shopping Guide and how does it help supply personnel? MATERIAL PROCUREMENT Learning Objectives:  Recognize  the  procedures  to requisition  supplies  and  material  through  the  Navy supply  system.  Recall  the  purpose  of  MILSTRIP. Recognize the documents used to order material. Recall the  purpose  of  UMMIPS.  Recall  how  the  priority designator is determined. Recognize the purpose of the various types of CASREPs. Recall the purpose of MTR items. Once you have determined that a replacement part is required and you have its NSN, you are ready to order the part. In the Navy, this process is called procurement. Procurement is the process of obtaining materials and services to support the operation of an activity. The two basic methods of procurement in the Navy are by requisition and by purchase. As a division supply petty officer or perhaps as a work center supervisor, you will play an important role in the procurement of materials and services. If you are in one of these positions, you will be required to decide the necessity of material requested by the work center supervisors    in    your    division    or    by    your    own subordinates. You also must know if the material is authorized for use by your command, division, or work center. In addition, you must determine the importance of the material over other material and properly assign a priority designation. As a supply petty officer or work center supervisor, you will be the principal adviser to your division leading chief petty officer and division officer on all matters of procurement at the division level. MILITARY STANDARD REQUISITIONING AND ISSUE PROCEDURE (MILSTRIP) A requisition is a request for materials or services. The most common method of requisitioning materials is through a DoD system known as the Military Standard Requisitioning and Issue Procedure (MILSTRIP). As the name implies, MILSTRIP is used for the requisitioning and issuing of materials. Many transactions  must  take  place  between  the  time  a requisition is submitted and the material is received. Some of these transactions include the furnishing of supply status information, follow-up requests, redistribution orders, referral orders, and cancellation requests. Such transactions are all an integral part of the MILSTRIP. With the exception of certain classes of material, MILSTRIP is used for ordering material through the Navy supply system. These exemptions are listed  in   Operating     Procedures  Manual     for MILSTRIP/MILSTRAP, NAVSUP P-437. Requisition Documents MILSTRIP  requisitioning  is  based  upon  coded, single line item (one stock number) documents. Several types of documents are used to order material. The most commonly used documents are as follows: 1. NAVSUP Form 1250-1 2. DD Form 1348 3. DD Form 1348-6 4. DD Form 1149 Under certain circumstances, requisitions may be submitted either by message or by letter. The following paragraphs describe the purpose and basic  requirements  for  the  forms  just   mentioned. Complete information concerning the preparation of these documents is contained in NAVSUP P-485. NAVSUP Form 1250-1 (fig. 7-9) is used as a consumption document by all forces and as a MILSTRIP requisitioning/issuing document by nonautomated ships of the submarine forces. The form is used primarily for procuring materials or services. Submarine tenders or
