U.S. Revokes Antidumping Duty Order on Barium Carbonate from China
Estimated reading time: 3 minutes
On October 3, 2025, the U.S. Department of Commerce announced it is ending the Antidumping Duty (AD) Order on barium carbonate from the People’s Republic of China.
The Department of Commerce started the fourth review of the AD Order on July 1, 2025. This “sunset review” looked at whether the duty order should continue. In these cases, U.S. law allows for review every five years.
No company or party in the United States responded to Commerce’s notice about this review. According to section 751(c)(3)(A) of the Tariff Act of 1930, if no one responds, the Department of Commerce must revoke the order after 90 days.
Barium carbonate is covered by this order, no matter what form or grade it is. Its tariff code is 2836.60.0000 under the Harmonized Tariff Schedule of the United States. The written description of the product matches the legal definition given in the order.
Because no U.S. parties responded, the Department of Commerce is revoking the AD Order. This means the order will no longer apply starting from August 20, 2025. Entries of barium carbonate made before this date will still have to follow the earlier rules.
The Department of Commerce will instruct U.S. Customs and Border Protection to lift all suspensions for the period after August 20, 2025.
Any requests for reviews about imports before August 20, 2025, may still be considered.
Details of this decision are published in Federal Register Volume 90, Number 190, on October 3, 2025.
