US PVC: Negotiations for March polyvinyl chloride export pricing wrapped up last week with offers falling $30/mt compared with initial nominations that met market pushback. Offers that ranged between $920 and $935/mt FAS Houston settled between $890 and $905/mt FAS Houston, with market participants terming deals above $900/mt FAS Houston as unworkable, although settlement at $905/mt FAS Houston illustrated willingness to reach that level. However, multiple deals were heard done last week at $890/mt FAS. Producers had been bullish on seasonal PVC demand, with the spring construction season looming and expectations of limited export volume availability tied to Shintech’s turnaround at its 1.4 million mt/year PVC plant in Freeport, Texas. In addition, Westlake Chemical’s supply availability has thinned due to operational issues within its system, according to sources, further shrinking available export volumes. Even so, traders say weak global demand deflated initial price nominations to levels where deals were considered workable. Sources also said Formosa Plastics expects to produce 85-90% of its normal export volume in March after restarting a 681,000 mt/year cracker in Point Comfort, Texas, in mid-February after a two-month outage.
