Decision to Extend the Taxable Period of Anti-Dumping Duty on Dipotassium CarbonateOriginating in the Republic of Korea
Today, a Cabinet Order was adopted to extend the taxable period of anti-dumping duties on dipotassium carbonate originating in the Republic of Korea.
The Cabinet Order will be made public on July 8, 2026, and the taxable period will be extended until July 7, 2031.
Background
● The Government of Japan has been imposing anti-dumping duties on dipotassium carbonate originating in the Republic of Korea (the rates of the anti-dumping duties: 30.8%) in accordance with provisions of the Customs Tariff Law and relevant orders. The taxable period is from March 25, 2021, to June 23, 2026.
● The investigating authority which consists of the Ministry of Finance and the Ministry of Economy, Trade and Industry initiated a review in August 2025, upon a request made in June by the domestic producers, namely AGC Inc., to extend the current taxable period of the anti-dumping duties on dipotassium carbonate originating in the Republic of Korea.
● The review results show that the expiry of the duty would be likely to lead to recurrence of dumping and injury caused by dumped imports to the domestic industry.
● On June 23, 2026, the Council on Customs, Tariff, Foreign Exchange and Other Transactions (the Trade Remedy Subcommittee of the Customs and Tariff Committee), reported to the Minister of Finance that it was appropriate to extend the taxable period of anti-dumping duties on dipotassium carbonate originating in the Republic of Korea for five years, based on the results of the review carried out by the Government.
