Last week, new developments continued to emerge in global tariff policies.

The Office of the United States Trade Representative formally launched a new Section 301 investigation on March 11, planning to investigate 16 trading partners, including China, over their manufacturing capacity and industrial policies. This will provide a basis for potential future tariff measures.

Meanwhile, following a previous ruling by the U.S. Court of International Trade that partially invalidated certain global tariffs, U.S. Customs stated that it is establishing an automated process and will begin refunding relevant tariff payments to businesses as early as the end of April.

Mexico officially implemented new tariff measures, imposing an additional 25% to 50% tariff on 1,463 tariff lines of goods imported from non-FTA countries such as China, India, and South Korea. The measures cover a wide range of industries including textiles and apparel, footwear, small home appliances, furniture, toys, and automobiles.

Global trade policies remain in constant adjustment, and future changes in tariffs warrant continued close attention.
