    (a) In General.--If the provisions of section 1 require, the 
President--
            (1) may enter into a trade agreement with any foreign 
        country or instrumentality for the purpose of granting new 
        concessions as compensation in order to maintain the general 
        level of reciprocal and mutually advantageous concessions; and
            (2) may proclaim such modification or continuance of any 
        existing duty, or such continuance of existing duty-free or 
        excise treatment, as the President determines to be required or 
        appropriate to carry out any such agreement.
    (b) Limitations.--
            (1) In general.--No proclamation shall be made pursuant to

        less than 70 percent of the existing rate of duty.
            (2) Special rule for certain duty reductions.--If the rate 
        of duty in effect at any time is an intermediate stage under 
        section 1102(a) of the Omnibus Trade and Competitiveness Act of 
        1988, the proclamation made pursuant to subsection (a) may 
        provide for the reduction of each rate of duty at each such 
        stage proclaimed under section 1102(a) by not more than 30 
        percent of such rate of duty, and may provide for a final rate 
        of duty which is not less than the 70 percent of the rate of 
        duty proclaimed as the final stage under section 1102(a).
            (3) Rounding.--If the President determines that such action 
        will simplify the computation of the amount of duty computed 
        with respect to an article, the President may exceed the 
        limitations provided in paragraphs (1) and (2) by not more than 
        the lesser of--
                    (A) the difference between such limitation and the 
                next lower whole number, or
                    (B) one-half of one percent ad valorem.
