ad valorem

Whenever any limitation on the amount by which or to which any rate of duty may be decreased or increased pursuant to a trade agreement is expressed in terms of an ad valorem percentage, the ad valorem amount taken into account for purposes of such limitation shall be determined by the President on the basis of the value of imports of the articles concerned during the most recent representative period.
