Chinese petcoke buyers turning to Russia, Mideast after US tariffs

Chinese importers of petroleum coke are buying more volumes from Russia and the Middle East due to a hefty tariff on shipments from the United States, previously one of China's main sources of the material used in aluminium and cement production.

China slapped a 25% tariff on US petroleum coke, a byproduct of oil refining, from August 23 as part of its escalating trade row with the United States.
