Sunset Reviews of AD/CVD Orders on Magnesia Carbon Bricks from China and Mexico
What happened
On November 3, 2026, Commerce published final results in expedited third sunset reviews of the antidumping duty orders on magnesia carbon bricks from Mexico (A-201-837) and China (A-570-954), finding that revocation would likely lead to continuation or recurrence of dumping, at weighted-average margins up to 57.90 percent for Mexico and 236.00 percent for China, applicable November 4, 2026. In a separate final result the same day, Commerce found in the expedited third sunset review of the countervailing duty order on magnesia carbon bricks from China (C-570-955) that revocation would likely lead to continuation or recurrence of countervailable subsidies, at rates of 3.00% for RHI Refractories Liaoning Co., Ltd., RHI Refractories (Dalian) Co., Ltd. and Liaoning RHI Jinding Magnesia Co., Ltd. (collectively, RHI), and 232.63% for Liaoning Mayerton Refractories and Dalian Mayerton Refractories. Commerce conducted the expedited 120-day reviews after receiving no substantive response from any respondent interested party. The reports do not state the full scope of the subsidy rate for the Mayerton companies or any further procedural step.
