Steel’s Domino Effect: US Tariffs Now Threaten Entire EU Manufacturing Chain

A trade policy once confined to steel mills is now threatening to topple dominoes across the entire European manufacturing chain. The United States’ decision to apply punitive tariffs to a growing list of “derivative” products—goods that contain steel—is creating a crisis that extends far beyond the metal industry, hitting everything from heavy machinery to consumer electronics.
The expansion is already significant. In August, the US added 407 product categories to its tariff list, including wind turbines, bulldozers, and mobile cranes. With a new consultation underway, European leaders fear that this is just the beginning and that the list will continue to grow ad hoc, adding items like window frames and doors.
This policy creates a climate of extreme unpredictability. Luisa Santos of the industry confederation BusinessEurope stated the relationship with the US is “becoming quite turbulent” because of this power to unilaterally expand the tariff lists. This robs businesses of the stability they need to invest, hire, and plan for the future.
The practical difficulties are immense. Bernd Lange, a senior German MEP, highlighted the absurdity of the situation by describing how a motorcycle factory is forced to overstate the steel content of its vehicles. This is done to avoid the risk of a 200% penalty for misdeclaration, a telling example of the dysfunction the policy has created.
Faced with this domino effect, European industry is pushing back. Eurofer, the steel trade association, is calling for strong new trade measures to protect not only steel producers but the millions of manufacturing jobs they sustain across the continent. The fear is that without intervention, the damage from these tariffs will be widespread and severe.
