On 20 August 2018 China’s Ministry of Commerce started to implement anti-dumping duties ranging from 23.1 per cent to 75.5 per cent on synthetic halogenated butyl rubber from the United States, the European Union and Singapore.
The ministry, which had imposed temporary anti-dumping duties on the synthetic rubber from those countries in April, said the 75.5 percent tariff would apply to U.S. rubber made by Exxon Mobil (XOM.N) and other U.S. companies.
Arlanxeo Belgium faces a 27.4 percent tariff, while Exxon Mobil Chemical and other companies in the EU face 71.9 percent. Arlanxeo Singapore has been hit with a 23.1 percent tariff and other Singapore firms 45.2 percent.
