The Trump administration is reportedly evaluating a proposal to reduce tariffs on auto parts.

This consideration comes as a deadline of May 3, 2025 approaches.

The proposal could exempt car parts from China-related tariffs, originally meant to curb fentanyl production.

Additionally, it would allow parts manufacturers to bypass tariffs on steel and aluminum, a process known as “destacking.”

Despite these potential exemptions, a 25% tariff on all foreign-made cars and auto parts is still set for May 3, 2025.

The White House has not commented on this matter.

🧠 Food for thought

1️⃣ The North American auto industry operates as a deeply integrated ecosystem, making tariffs particularly disruptive

The modern automotive industry relies on a complex cross-border supply chain, where parts regularly cross borders multiple times before becoming finished vehicles.

Research from the Chicago Fed shows that 38% of the value added in vehicles produced in Mexico for the US market actually originates from the United States, demonstrating how intertwined production has become across North America1.

This integration developed over decades following agreements like the 1965 Canada-US Automotive Products Agreement and later NAFTA, creating an interdependence that makes isolated tariff policies particularly challenging to implement without widespread consequences.

When components cross borders multiple times during manufacturing, tariffs can compound, creating what industry experts call a “cascade effect” where the same part might be taxed repeatedly at different stages of production.

The potential exemption for auto parts reflects an acknowledgment of this reality, as disrupting the supply chain can affect production across all three North American countries simultaneously.

2️⃣ Tariffs create clear winners and losers across the automotive ecosystem

Historical evidence shows that automotive tariffs produce complex economic tradeoffs, helping some industry segments while harming others.
