Washington, D.C. — In a dramatic escalation of his "America First" trade policy, U.S. President Donald Trump announced a new round of punishing tariffs on a range of imported goods, set to take effect on October 1st. The announcement, made on his social media platform Truth Social on September 25th (local time), targets pharmaceuticals, heavy trucks, and household furnishings, marking the administration's latest push to compel foreign companies to establish manufacturing operations within the United States.

Pharmaceutical Industry Targeted with 100% Tariff 

The most significant measure targets the global pharmaceutical sector. President Trump stated that his administration will impose a 100% tariff on "any branded or patented Pharmaceutical Product" imported into the U.S. The tariff, which effectively doubles the cost of these medicines, includes a critical exemption: it will not apply to companies that are "breaking ground" on or are "under construction" building drug manufacturing plants in America.

This move is seen as a clear ultimatum, compelling drug makers to onshore their production. The implications for consumers and healthcare costs are potentially massive, given that the U.S. imported approximately $233 billion in pharmaceuticals in 2024. For countries like South Korea, whose pharmaceutical exports to the U.S. totaled about $1.49 billion (approximately 2 trillion KRW) last year, companies exporting to the U.S. market are expected to face significant disruption and pressure to localize production.

Tariffs on Vehicles and Furnishings 

In addition to pharmaceuticals, the new tariffs will hit other major imported sectors:

Heavy Trucks: A 25% tariff will be imposed on all "Heavy (Big!) Trucks" manufactured outside the U.S. starting October 1st. The President explicitly stated the goal is to protect domestic manufacturers such as Peterbilt, Kenworth, Freightliner, and Mack Trucks from "unfair outside competition." The measure follows an investigation initiated under Section 232 of the Trade Expansion Act, which examines the impact of imports on national security.
Household Goods: Tariffs will also be applied to specific home goods, citing a "massive flooding" of foreign products:

Kitchen Cabinets and Bathroom Vanities: A 50% tariff will be applied.
Upholstered Furniture: A 30% tariff will be charged on furniture filled or covered with cotton.
These tariffs, according to the President, are necessary to protect American manufacturing processes "for National Security and other reasons."

Economic Impact and Outlook 

The announcement has injected a fresh wave of uncertainty into the global economic outlook. While the administration argues the tariffs will cut deficits and boost domestic manufacturing and jobs—a core tenet of the "America First" agenda—critics and economists warn of potential consequences. Concerns include heightened inflation, as the cost of the tariffs is largely passed to American consumers and businesses, and slowed economic growth. Industry analysts suggest the tariffs could force major shifts in global supply chains and lead to immediate price increases for everything from critical medicines to home furnishings, posing a new challenge for the U.S. economy.
