U.S. container imports dropped 5.5% in April as importers contend with trade policy uncertainty and geopolitical risks, supply chain technology provider Descartes Systems Group said on Friday. Containerized import volumes have been hit by U.S. President Donald Trump's shifting trade policies and Iran's closure of the Strait of Hormuz — a vital shipping corridor for energy supplies — following U.S.-Israeli strikes on the country. Import trends are seen as a measure of the health of the U.S. economy — rising when the economy is strong and falling when the economy is weak.
