As reported in this blog on end of August, Japan lowered CVD (Counter Vailing Duty) rate from 27.2% to 9.1% based on the advice from WTO. The lowered rate was effective on Sept. 01.
On Sept 29, Hynix Korea requested to Japanese MOF to abolish CVD completely because the subsidy in question was no longer beneficial after 2003 which is the period for the investigation.
Japanese MOF and METI started re-investigation of the circumstance Hynix pointed out from October 15.
