The EU's chief negotiator, Ignacio Garcia Bercero, described the deal as the "most ambitious" the EU has negotiated with an external partner, Yonhap reported.
The talks between Asia's fourth-largest economy and the world's single-largest economic bloc began in May 2007, with auto trade and industrial tariffs posing initial roadblocks, according to Yonhap.
The two sides have tentatively agreed to abolish or phase out tariffs on nearly all goods within three years and on all industrial goods within five years, Yonhap reported.
The talks had been scheduled to last through Tuesday, but an official announcement of a deal hadn't been expected to be made until a worldwide economic summit early next month in London, South Korean officials had said.
