As soon as practicable after the close of the two-year period beginning on the date on which any waiver under section
2511
(a) of this title first takes effect, the President shall prepare and transmit to Congress a report containing an evaluation of administrative practices under any provision of law which requires determinations to be made of the country of origin of goods, products, commodities, or other articles of commerce. Such evaluation shall be accompanied by the President’s recommendations for legislative and executive measures required to improve and simplify and to make more uniform and consistent such practices. Such evaluation and recommendations shall take into account the special problems affecting insular possessions of the United States with respect to such practices.
