Tariffs on clothing and other imports from China went into effect on Sunday, escalating the trade war in a move expected to squarely hit consumers.

The U.S. tariffs of 15% on tools, apparel items, some footwear and many electronics will be charged on imports valued at $111 billion last year, according to an analysis by The Wall Street Journal. Additional tariffs of 15% on $156 billion of smartphones, laptops, toys, videogames and other products have been postponed until Dec. 15, after the period when goods are typically imported for the holiday season.

“Absolutely worth it, we don’t want to be servants to the Chinese!” President Trump said Sunday in a tweet, referring to the process of tariffs forcing American importers to look for other suppliers. The tariffs are “about American freedom,” he added in another tweet. “There is no reason to buy everything from China!”

Mr. Trump cited the views of economist Peter Morici, who was interviewed Sunday on Fox News and said the tariffs would impact average Americans “not as much as the critics say” due to shifts in exchange rates and supply chains.

Business groups and others criticized the tariffs as harmful for American companies and consumers.
