The signal

Honda and other automakers are sounding alarms over pending tariff increases set to take effect January 1 on Canadian steel and automotive imports. Jennifer Thomas, Honda's senior vice president of corporate affairs, called the potential doubling of tariffs "catastrophic" for the industry during talks at the Reuters Automotive USA conference.

The threat centers on renegotiations of the trilateral trade agreement between the U.S., Mexico, and Canada, with the Trump administration pushing for stricter "rules of origin" requirements that would increase North American content mandates to 82 percent. These dynamics directly threaten Honda's plans to build an eighth assembly plant in North America, signaling that manufacturers may redirect capital investment elsewhere if trade conditions deteriorate.

The situation underscores how tariff policy functions as a critical lever in supply chain strategy, affecting not just import costs but also facility location, capacity planning, and regional competitiveness.

What if tariffs on Canadian steel and autos double on January 1?

Model the impact of tariffs increasing from current rates to 50 percent on Canadian steel and 25 percent on Canadian autos, effective January 1. Simulate effects on component sourcing costs, vehicle assembly economics in Mexico and Canada, and total landed costs for North American auto production. Include secondary effects on supplier profitability and capacity utilization across the North American auto supply base.

What if rules of origin are enforced at 82 percent North American content?

Model the supply chain reconfiguration needed to achieve 82 percent North American content across vehicle production. Simulate sourcing constraints, identify components that cannot currently meet content thresholds, calculate required supplier base expansion in the U.S., Mexico, and Canada, and estimate timing and cost impacts for compliance. Include effects on vehicle pricing and competitiveness.

What if manufacturers shift investment away from North America to other regions?

Simulate a scenario where major automakers reduce capital expenditure in North America by 15-25 percent and redirect facility investments to alternative regions (Southeast Asia, Eastern Europe). Model impacts on regional capacity, lead times for North American sourcing, supplier utilization rates, and availability of key components currently sourced from Mexico and Canada.
