The title was only recently able to roll out the worldwide buy, after the New York Times bought out the Washington Post's share in the IHT last January.
IHT president and chief operating officer Richard Wooldridge said: "Following the buyout by the New York Times, we can now offer global buys - America, which is the New York Times, and Europe and the United States through the Tribune."
Companies which have so far signed up for the new package include ABN-Amro, Burberry and Maxmara.
Randy Weddle, IHT Asia-Pacific managing director, said the move now brings the newspaper up to par with the competition.
