U.S. exporters large and small scrambled on Tuesday to urge foreign customers not to abandon deals supported by the U.S. Export-Import Bank, which will be forced to halt new business at midnight as its charter expires.

There are about 195 pending transactions still in its approval pipeline that will be frozen by the lapse, with requested amounts totaling $9.14 billion, according to Ex-Im data circulated to Democratic lawmakers. The amounts include 14 loan guarantees worth $3.33 billion, and 137 trade insurance requests worth $163 million.

Companies affected range from giants including aircraft maker Boeing Co. and General Electric Co. to small exporters of specialty oilfield equipment.
