Rain CII, which was displaced to Kingwood, Texas, after Hurricane Katrina in 2005, has opened its $5.6 million corporate headquarters in Covington.

Rain CII, which produces materials used in aluminum, steel and titanium dioxide, announced its plans to return to Louisiana in October 2013. A ribbon-cutting ceremony was held Thursday.

Its new headquarters is in the Northpark Business Park at 1330 Greengate Drive in Covington.

Until Katrina, the company, then called CII Carbon, occupied a building on the University of New Orleans campus. Most of the employees moved to Kingwood, near Houston, where there was available office space.

Rain CII’s operations include calcining plants at nine production sites in the United States, India and China.

The jobs based in Covington include commercial, operations and administrative positions.

The state provided a package of incentives to help ease the move, including a $3.6 million performance-based grant to offset relocation costs. The company will also be eligible for a $2 million modernization tax credit.
