The Tariff Ripple Effect: How a 10% Tariff on Canadian Heavy Oil Could Drive Up U.S. Trucking Costs
Exploring the Impact on Diesel Prices, Supply Chains, and the Broader Economy

Key Refined Products from Canadian Heavy Oil:
Diesel Fuel: Vital for trucking, rail, and industrial machinery.
Gasoline: Used primarily for personal and commercial vehicles.
Jet Fuel: Powers commercial and cargo aviation.
Asphalt: Essential for road construction and maintenance.
Petrochemicals: Feedstocks for plastics, chemicals, and synthetic materials.
Heavy Oil Imports and Key Refineries:
Import Volume: The U.S. imports approximately 4 million barrels of Canadian heavy oil daily.
Main Refineries Using Heavy Oil:
Motiva Port Arthur Refinery (Texas): One of the largest U.S. refineries, optimized for heavy crude processing.
Marathon Petroleum's Garyville Refinery (Louisiana): Major user of Canadian heavy crude.
Phillips 66 Refinery (Wood River, Illinois): Processes significant volumes of heavy crude.
Valero Energy Refineries (Multiple Locations): Depend heavily on Canadian heavy crude.
BP Whiting Refinery (Indiana): Specifically upgraded to handle heavy crude.
Alternative Sources for Heavy Oil:
Venezuela: Significant reserves but hampered by sanctions and infrastructure issues.
Mexico: Declining heavy crude output.
Middle East: Limited supply of heavy crude, more focused on light sweet crude.
U.S. Domestic Production: Primarily light crude, requiring blending for certain refinery configurations.
Is Canadian Heavy Oil Key?
Yes. The U.S. is heavily reliant on Canadian heavy crude due to:
Proximity and cost-effectiveness.
Existing infrastructure (pipelines and refineries optimized for Canadian blends).
Stable political and trade relations (historically).
Key Impacts on U.S. Consumers:
Higher diesel and gasoline prices.
Increased transportation and shipping costs.
Potential rise in consumer goods prices due to supply chain cost increases.
Strain on industries dependent on fuel-intensive logistics.
Most Impacted: U.S. trucking industry with significant cost hikes.
