Import pricing for spot cargoes of polyethylene and polypropylene are expected to remain stable or slip further as availability improves and traders turn to short sales to move product in what had been a stagnant buying market for much of March, sources said. Many buyers from Brazil to South America’s Pacific Coast kept spot and contract volumes to a minimum last month with the expectation April would bring better availability from the US, sources said, adding that many PE traders opened the month motivated to move product before US producers potentially make more resin available for export in the second half of the month. PP buyers have talked the South American spot market as “oversupplied” after regional producers ramped up reduction in late February and throughout March on lower feedstock costs, sources have said. In the PVC market, West Coast South America buyers have seen import pricing fall much faster than their Brazilian counterparts, with availability from traditional trade partners serving as a key driver. As US export pricing has fallen, WCSA importers have enjoyed lower CFR pricing and similar pricing for Asian cargoes, while Brazilian importers have had to deal with limited exports from Europe, where production issues have hampered trade, sources said.
