The U.S. Department of Commerce preliminarily determines that certain refractory brick samples tested by CBP do not constitute magnesia alumina carbon (MAC) bricks and fall under existing AD/CVD orders on magnesia carbon bricks from China (cases A-570-954 / C-570-955). Commerce also flags inconclusive results for additional samples and invites interested party comments.
