A request/offer system for the achievement of tariff reductions in which the parties involved aim at reducing tariffs to zero (i.e. at eliminating tariffs) on a reciprocal basis in complete sectors.  During the Uruguay Round, some Members used this modality to liberalize several sectors including pharmaceuticals. The Information Technology Agreement is a recent example of this approach.
