What were the major imports and exports during the 1940s in America?

During the 1940s, particularly during World War II, America's major exports included military equipment, machinery, and food supplies, as the country supported its allies through programs like Lend-Lease. Key imports included raw materials such as rubber, oil, and strategic metals, which were crucial for wartime production. The decade also saw a significant trade shift due to wartime needs, with many industries focused on supporting the war effort. Post-war, the U.S. began to expand its consumer goods exports as the economy transitioned to peacetime production.
