(a) Authority to Establish Restrictions.—The Secretary of Defense may establish restrictions on the ability of eligible patrons of commissary and exchange stores located outside of the United States to purchase certain merchandise items (or the quantity of certain merchandise items) otherwise included within an authorized merchandise category if the Secretary determines that such restrictions are necessary to prevent the resale of such merchandise in violation of treaty obligations of the United States or host nation laws (to the extent such laws are not inconsistent with United States laws).
(b) Limitations on Use of Authority.—In establishing a quantity or other restriction, the Secretary—(1) may not discriminate among the various categories of eligible patrons of the commissary and exchange system; and
(2) shall ensure that the restriction is consistent with the purpose of the overseas commissary and exchange system to provide reasonable access for eligible patrons to purchase merchandise items made in the United States.
