Washington: The administration of U.S. President Donald Trump has decided to add refrigerators, washing machines, dryers, and other items to the list of derivatives subject to a 50 percent steel tariff, a Commerce Department notice showed Thursday, a move likely to affect South Korean electronics firms.

According to Yonhap News Agency, the department's Bureau of Industry and Security published a notice on the Federal Register, indicating that the tariff will be assessed on these products based on the value of the steel content in each of them. The measure is set to take effect on June 23.

The list of affected items has expanded to include eight derivatives, which also consist of dishwashers; chest and upright freezers; cooking stoves, ranges, and ovens; food waste disposals; and welded wire racks.

This decision is expected to impact two major South Korean firms, Samsung Electronics Co. and LG Electronics Inc., both of which export home appliances to the U.S.
