President Trump’s decision to double tariffs on imported steel and aluminum — raising them from 25% to 50% — is generating strong reactions across the supply chain, manufacturing, and logistics industries. The move, announced at a rally in Pennsylvania, is intended to support the U.S. steel industry and domestic production. However, many experts warn that the tariffs could drive up costs, strain supply chains, and invite retaliatory measures from key trading partners.

The new tariffs, which will take effect on June 4, follow recent tensions over global steel production and trade imbalances. The policy also comes at a time when industries that rely heavily on steel and aluminum—including automotive, construction, and packaging—are already facing rising costs and supply chain disruptions.

Supply chain voices are raising concerns about the new steel and aluminum tariffs. Here are some of their reactions:

Michael Knight, President & CEO, Endries International Inc: “The doubling of Section 232 tariffs on steel and aluminum is hard to wrap my head around. For industrial fastener suppliers and the OEMs that rely on us, this means headaches turn into full-blown migraines.”

Jason Miller, Supply Chain Professor: “Raising steel and aluminum tariffs to 50% is, simply put, horrible economic policy. This makes exports of goods containing steel and aluminum less competitive and may be the final straw that encourages EU retaliation.”

Andrea Lisi, CFA, Founder, Lisi Quant Analysis LLC: “We anticipate that companies impacted by these tariffs will likely pass the increased costs onto consumers. Affected industries, including automotive, construction, energy, and consumer goods, face heightened input costs.”

Dan P. Owens, Strategic Business Leader: “Another round of potential tariff hikes is on the horizon. Whether or not it happens, one thing is certain—uncertainty is the only constant in our space.”

Ajay Srivastava, Trade Policy Analyst: “Higher tariffs hit costs hard and may slow down growth in steel-related industries. It’s important for India to carefully weigh retaliation without escalating trade wars further.”

The new tariffs are hitting at a time when global supply chains are already dealing with a lot of change and uncertainty. Many companies are now watching to see how higher prices and possible retaliation from other countries could shake up the economy even more.
