+# Import Restraint
+
+## Definition
+
+Government policies designed to limit or prohibit the entry of foreign goods into a domestic market, typically through tariffs, quotas, or outright bans. These measures were central to mercantile policy aimed at protecting domestic industries and preserving precious metals within the nation.
+
+## Source Chapter
+
+Book IV, Chapter 1
+
+## Context
+
+Smith identifies import restraints as the second major category of mercantile policy, alongside export promotion. He argues these restrictions harm national wealth by preventing access to cheaper or better foreign goods, raising prices for consumers, and disrupting the natural benefits of international division of labour.
