Port Laredo, Texas, was the No. 3-ranked U.S. trade gateway in March, totaling $31.3 billion in two-way commerce, a 13% year-over-year increase.

Port Laredo’s top imports from Mexico into the U.S. included auto parts ($2.4 billion), computers ($2 billion), passenger vehicles ($1.63 billion) and heavy-duty trucks ($963 million).
