(a) A person must use rated orders as necessary to obtain:

1. (1) Items that will be physically incorporated into other items to fill rated orders, including that portion of such items normally consumed or converted into scrap or by-products in the course of processing;
2. (2) Containers or other packaging materials required to make delivery of the finished items against rated orders;
3. (3) Services, other than contracts of employment, needed to fill rated orders; and
4. (4) MRO needed to produce the finished items to fill rated orders.

(b) A person may use a rated order to replace inventoried items (including finished items) if such items were used to fill rated orders, as follows:

1. (1) The order must be placed within 90 days of the date of use of the inventory.
2. (2) A DO rating and the program identification symbol indicated on the customer's rated order must be used on the order. A DX rating must not be used even if the inventory was used to fill a DX-rated order.
3. (3) If the priority ratings on rated orders from one customer or several customers contain different program identification symbols, the rated orders may be combined. In this case, the program identification symbol P4 must be used (that is DO-P4).

(d) For combining rated and unrated orders:

1. (1) A person may combine rated and unrated order quantities on one purchase order provided that:

   1. (i) The rated quantities are separately and clearly identified; and

   2. (ii) The four elements of a rated order, as required by § 789.12, are included on the order with the statement required in § 789.12(a)(4)(i) modified to read:

      This purchase order contains rated order quantities certified for national defense use, and you are required to follow all the provisions of the Agriculture Priorities and Allocations System regulation in 7 CFR part 789 only as it pertains to the rated quantities.

2. (2) A supplier must accept or reject the rated portion of the purchase order as provided in § 789.13 and give preferential treatment only to the rated quantities as required by this part. This part must not be used to require preferential treatment for the unrated portion of the order.
3. (3) Any supplier who believes that rated and unrated orders are being combined in a manner contrary to the intent of this part or in a fashion that causes undue or exceptional hardship may submit a request for adjustment or exception as specified in § 789.60.
