United Parcel Service said Monday it’s acquiring TNT Express, a Dutch shipping company, for $6.8 billion. The deal would increase the American company’s market share in Europe and open doors to the industry in China. About 36 percent of its combined revenues would come from outside the U.S. after the merger, compared with 26 percent right now. It’s the biggest acquisition in UPS’s 105-year history—it bought Overnite Corp. for $1.2 billion in 2005.
