An important trend since March 2016 has been record exports of polymers from China. Exports of PVC surged in March and continued high through August, as did exports of PET. Shipments of polyolefins were heavy from March through June/July, but slowed in August.
Nearly 800,000 tons of sheet and other flat products (film, foil and strip) made from PVC were traded globally in 2014, up 3% from the prior year. Trade volume through June of 2015 was down 3%, based on reporting countries. Global trade volume is an indicator of global demand.
