Baltimore is among the top 20 ports in the United States by tonnage and number of containers handled, according to the US Bureau of Transportation Statistics.
Last year, it handled a record 1.1 million 20-foot equivalent units (TEU) of containers — a measure of volume for shipping containers.
Container imports via Baltimore amounted to 2.1 percent of the total for all US ports, according to Allianz Trade.

Its private and public terminals handled 847,158 autos and light trucks last year, more than any other US port for the 13th year in a row, according to Maryland state figures.
