The Trump administration dialed down trade tensions further, cutting tariffs on lower-value packages from China and Hong Kong.

The WSJ’s Gareth Vipers and Jiahui Huang write that the White House late Monday ordered the “de minimis” duty on shipments from China and Hong Kong reduced to 54% from 120%. The de minimis exemption allows companies to avoid import taxes on international shipments with a retail value of less than $800. Before suspending it for China as of May 2, it had fueled the rise of Shein, Temu and other e-commerce companies. Its loss forced online retailers to raise prices and rethink their business models.

Importers, shipping companies and global markets welcomed the 90-day reprieve agreed to by the U.S. and China to roll back tariffs. Many companies said they would quickly get their goods onto ships destined for American ports, the Journal’s Suzanne Kapner, Ruth Simon and John Keilman report. But don’t count on a massive renewed surge of trans-Pacific container shipments, said Gene Seroka, the executive director of the Port of Los Angeles. Companies that supply critical goods such as healthcare products as well as toy makers and other seasonal-product purveyors might take this moment to restock, he said. The National Retail Federation also said some retailers might find some relief from the cut in the base tariff on Chinese goods to 30% from 145%, the WSJ Logistics Report’s Liz Young writes. However, the tariff cut is unlikely to spur frontloading of the sort that sent container shipments surging ahead of the “Liberation Day” duties, Seroka said. The effect of new tariffs has been stark, with Seroka saying he expects imports to the port to end May down 25% year-over-year.

The trade war has brought on boom times for the ultimate U.S.-based tariff refuges: Foreign-trade zones.

The WSJ’s Owen Tucker-Smith writes that companies can import products temporarily tariff-free while they are stored or used to assemble other goods at warehouses in these zones. Since Trump’s tariff blitz began, inquiries have quadrupled at the U.S.’s roughly 260 FTZs. One of these warehouses in Arizona is teeming with new business from companies stashing aluminum poles, ice picks, carabiners, firearm safes and other imported items. FTZs have been around since 1934, when they were allowed to ease some of the effects of the Smoot-Hawley tariffs. FTZ operators charge companies setup and storage fees, which are small compared with the upfront tariff bills some importers face.

The facilities don’t solve all tariff challenges: If duties go down, as they did with China on Monday, companies will still be on the hook for the amount assessed when their goods entered an FTZ.

President Trump sees future commerce and possible conflict in the Arctic. As countries race to access its thawing seas, he has called for the U.S. to make a new fleet of icebreakers. The Journal’s Daniel Michaels writes that engineers in Finland are lining up to help.

With much of its trade shipping via the ice-prone Baltic, Finland has mastered the tricky business of designing and building these specialized vessels. One Finnish company, Aker Arctic, uses a 246-foot-long ice-simulation tank to design ships for Canada, Sweden and other countries, and wants to play a role in U.S. plans, too. America could use the help after struggling to build icebreakers itself. Trump, after a recent meeting with Finland’s president, said in a social media post that he wanted to strengthen ties, and that includes the purchase and development of a large number of icebreakers.
