GENEVA: Saudi Arabia has filed a World Trade Organization complaint over EU anti-dumping duties on imports of a chemical compound used to make synthetic fibers and plastic bottles, according to a document published on Thursday. In the complaint, dated Aug. 17 but circulated to WTO members on Thursday, Saudi Arabia charges that the EU unfairly imposed provisional anti-dumping duties on imports of mono-ethylene glycol. The chemical compound is used in a variety of industrial processes, including to produce polyester fibers and components for manufacturing plastic bottles. It is also used in the production of engine coolant for the automotive industry, as antifreeze, solvents and a dehydration agent in natural gas pipelines, among other things.
