12.715—Evaluating offers.
        
        (a) 
         Unless the head of the grantee organization or a designee at a level no lower than the grantee's designated awarding official determines otherwise, the offered price of a domestic end product is unreasonable when the lowest acceptable domestic offer exceeds the lowest acceptable foreign offer (see  § 12.705 ), inclusive of duty, by—
    
    
        
        (1) 
         More than 6 percent, if the domestic offer is from a large business that is not a labor surplus area concern; or
    
    
        
        (2) 
         More than 12 percent, if the domestic offer is from a small business concern or any labor surplus area concern.
    
    
        
        (b) 
         The evaluation in paragraph (a) of this section shall be applied on an item-by-item basis or to any group of items on which award may be made as specifically provided by the solicitation.
    
    
        
        (c) 
         If an award of more than $250,000 would be made to a domestic concern if the 12-percent factor were applied, but not if the 6-percent factor were applied, the head of the grantee organization or a designee at a level no lower than the grantee's designated awarding official shall decide whether award to the domestic concern would involve unreasonable cost.
