This paper studies how Egyptian importing firms adjust when a product becomes subject to an anti-dumping investigation or duty. Using firm–product–origin customs data from 2005 to 2016, the analysis documents an investigation effect, with firms reducing quantities and facing higher import prices even before duties are applied. Enforcement generates similar but smaller adjustments. On the extensive margin, investigations slightly reduce entry and raise exit in the targeted product– origin pairs, pointing to a mild destruction effect and to reallocation rather than a collapse of trade. The results clarify how trade-remedy measures shape firm-level sourcing in developing economies.
