长期以来，国际钛白粉产业持续向氯化法工艺转型。2018年以前，我国氯化法钛白粉产量占比为2%～ 5%。近年来，在低碳环保的发展趋势下，氯化法成为钛白粉主流生产工艺。 自2019年以来，龙佰集团（002601.SZ）、中信钛业、鲁北化工（600727.SH）等企业相继新建或扩建氯 化法项目。例如，龙佰集团目前已形成66万吨/年氯化法产能；鲁北化工2024年拟定增募资不超3亿元， 用于扩建年产6万吨氯化法钛白粉项目。 有关数据显示，2024年全球钛白粉有效产能约1080万吨，其中中国产能占比56%，达605万吨。然而， 国内硫酸法产能仍占主导，占比接近84%，而国外氯化法产能占比超过87%。2024年，我国钛白粉产量 约476万吨，同比增长14.57%;氯化法钛白粉产量约66.3万吨，占比13.93%，同比下降4%。 2025年12月30日，天原股份（002386.SZ）发布公告称，其全资子公司宜宾天原海丰和泰有限公司拟在 现有厂区预留场地内，投资建设年产10万吨氯化法钛白粉项目，总投资14.83亿元。 天原股份证券部人士在接受《中国经营报》记者采访时表示，此次产能扩张主要基于国内外钛白粉市场 需求相对稳定。公司 ...

Group 1 - The core message of the article indicates a shift in U.S.-China trade relations from confrontation to dialogue, as emphasized by U.S. Treasury Secretary Scott Bessenet, signaling a more favorable environment for domestic and foreign trade enterprises in the U.S. market [3] - The adjustment in tariff policies is seen as a necessary response to the significant reduction in the U.S. trade deficit with China, which decreased by 25.2% to $175.38 billion from January to September compared to the previous year, with a dramatic 51.7% drop in September alone [6] - The U.S. government has implemented a series of tariff exemptions, including a comprehensive list of nearly 1,000 products, which includes essential technology items like integrated circuits and semiconductors, facilitating exports from domestic tech companies [8][12] Group 2 - The recent tariff exemptions are characterized by their precision, allowing Chinese companies to benefit significantly, as all exempted products are clearly marked with HSUS tax numbers, simplifying the process for companies to confirm eligibility [13] - The electronic information industry is identified as the primary beneficiary of these tariff exemptions, with significant reductions in tariffs for laptops, smartphones, and core components like integrated circuits and printed circuit boards [13] - The chemical industry, particularly in the coatings sector, is poised for growth due to reduced import costs for key raw materials like titanium dioxide and epoxy resin, which will enhance profit margins and stimulate demand from downstream industries [14]
