Whirlpool has filed a complaint with U.S. authorities, alleging that Samsung and LG’s American subsidiaries manipulated internal “transfer pricing” to lower tariffs on imported appliances. By undervaluing goods shipped from overseas units, Whirlpool claims the companies reduced their tax burden unfairly.

The complaint was submitted to the White House and U.S. Customs in August, reigniting tensions in a market where Samsung and LG now hold a combined 36% share, compared to Whirlpool’s 20%.

Both Korean firms deny wrongdoing, citing compliance with U.S. tax laws and highlighting their investments in domestic manufacturing.

Whirlpool’s move could influence future tariff policies and intensify scrutiny of multinational pricing strategies.
