As of March 1st China’s Yangtze River Protection Law has prohibited the transportation of acutely toxic chemicals and other dangerous substances by ship in the Yangtze River Basin, which includes the ports of Changshu, Jiangyin, Jingjiang, Ma An Shan, Nanjing, Nantong, Shanghai, Tiacang, Taizhou, Wuhan, Yibin Zhangjiagang and Zhengjiang.
The chemicals that are prohibited for transport are listed in the Catalogue of Hazardous Chemicals (2015);

and the Catalogue of Prohibited Dangerous Chemicals by Inland River (2019 edition).
Although the catalogues are in Mandarin, the targeted chemicals can be investigated by their unique Chemical Abstract Service (CAS) Registry Number.
American Club warned that members could face significant fines or other penalties, such as the revocation of their business license, if these requirements were violated. The Club said that members should ensure that they perform an appropriate level of due diligence to avoid the carriage of such cargoes. In addition, Members should consider any relevant clauses in their charter parties for carrying any chemicals though the Yangtze River Basin region.
