The White House asked key lawmakers on the steel issue to return to Washington on Thursday, and a formal White House announcement was expected to come after they had been briefed.

White House officials refused to discuss details of the president's decision, but congressional and steel industry officials, who spoke Wednesday on condition of anonymity, said they expected Bush to remove the tariffs in order to avoid the imposition of retaliatory tariffs on a wide range of American products.

The 15-nation European Union has vowed to retaliate against $2.2 billion of American products by mid-December unless the United States removes the steel tariffs, which were ruled illegal by the World Trade Organization.

The EU carefully chose its target list to cover a range of products from oranges to pajamas that would inflict maximum political pain in key swing states that Bush is hoping to win in next year's presidential race.

That put Bush in the difficult position of being forced to choose between angering businesses in those states or steelmakers in West Virginia, Pennsylvania and Ohio, also considered crucial to Bush's re-election chances.

At the same time, Bush's original tariff decision in March 2002 had unleashed a barrage of criticism from steel consuming industries that claimed the higher prices they were forced to pay cost more jobs than were saved at U.S. steel plants.

Steel industry officials said the administration was reviewing a number of proposals to soften the blow of lifting the tariffs, which Bush had imposed at a time when the domestic industry was staggering from a string of bankruptcies and thousands of lost jobs that the industry blamed on a surge of foreign imports.

Among the proposals being considered by the administration was making permanent early reporting requirements to detect any big influx of steel into the United States.

The reporting program requires steel importers to apply for import licenses, giving the government a quicker way to detect possible import surges than waiting for Customs Service data when the steel arrives at U.S. ports.

The administration also was expected to pledge an aggressive use of U.S. antidumping laws to impose tariffs on specific steel products should imports surge once the tariffs are lifted.

The administration package also was expected to include pledges to continue pursuing global negotiations aimed at getting other countries to limit government subsidies for their domestic steel producers and to curb overcapacity in the steel industry.
