The amount of import taxes paid by businesses in October was the highest in U.S. history, hitting $6.2 billion, according to a new report from a pro-trade group.

The amount paid in tariffs was more than double the tariff expenditures in October 2017, the group said.

It also said retaliatory tariffs on U.S. exports were taking a bite out of U.S. competitiveness. Among goods subject to tariffs, the group said, imports dropped 0.6 percent in October, indicating they were not having a major effect on foreign exporters. Exports subject to retaliatory tariffs, however, fell 37 percent.

Trump agreed last weekend to put the trade war with China on hold for 90 days while the two countries negotiate a deal. Stock markets reacted well to the news, but then plummeted after Trump threatened new trade barriers, calling himself a "Tariff Man" on Twitter.

Trump has also said he would withdraw from the North American Free Trade Agreement as he tries to persuade Congress to adopt an updated version of the deal, which he dubbed the United States-Mexico-Canada Agreement.
