The Port of Los Angeles moves ca. 8 million TEU every year; in other words, 8 million containers. Furniture, automobile parts, clothing and electronics are the major imports. The U.S. Army Corps of Engineers has made certain that even the largest ships in the world (e.g. the E and Triple E-class from Maersk) are able to sail into the 53-foot deep navigational channel.

For the record, 53 feet is 16 meters -- that's 3 meters deeper than the Elbe leading into Hamburg, even after the hypothetical and highly disputed "Elbvertiefung" (Elbe dredging).
