The South Carolina Port Authority (SCPA) handled 152,917 20-foot equivalent units (TEUs) last month, an increase of 18 percent from January 2014.
January's container traffic drove the fiscal year TEU amounts past the 1 million mark, ending at 1,072,438.
Overall, TEU volume is up 14 percent fiscal year to date.
"While ship sizes grow, driving increases in the number of container moves per vessel, our port continues to work well," SCPA President and CEO Jim Newsome said. "Strong terminal productivity ensures trucks can efficiently move cargo in and out of our facilities without delays."
Non-containerized cargo were also up 7 percent from last year.
In addition to the increase in cargo in the state’s ports, the SCPA board recently passed a ruling that allows the authority to oversee the construction of a site operations center project on the BMW Manufacturing Co.'s campus in Spartanburg, South Carolina. The industrial site, which belongs to the SCPA, is leased by the carmaker. The new project will include a 60,000-square foot-center and adjacent parking lot.
