European production is estimated by consultancy DeWitt to have fallen to 600 000-650 000 tonne in 2001, from 730 000 tonne in 2000 (Cefic's estimate). The drop reflects two plant closures (BP in Hull, UK, and Driftal in Portugal), production interruptions at Sisas during its divestment process, and weak demand. BASF bought Sisas' Feluy, Belgium, unit and Proviron took the Ostend, Belgium, facility. Low production rates have also been partly due to the lack of export demand to Asia. However, DeWitt says Russia is now exporting to China, replacing Korean exports: Russia benefits from a 50% reduction in import duty and VAT.
