February 4th News On February 2nd, the U.S. Department of Commerce announced the initiation of the first sunset review investigation into anti-dumping duties on difluoromethane (R32) imported from China. Chempricehub Analysis on R32, Bull-Bear Score: -1 The U.S. initiation of the anti-dumping sunset review investigation may lead to the maintenance or increase of import tariffs on Chinese-produced R32, reducing export demand and exacerbating domestic oversupply pressure, thereby exerting a downward impact on the spot price of R32. Reason: This investigation typically signals the continuation of trade barriers, suppressing Chinese exports, increasing the risk of domestic inventory accumulation, and putting pressure on prices.
