Ford builds over 80% of its US-sold vehicles domestically. However, this scale requires importing the most parts, so US tariffs on parts penalize Ford more heavily than companies that import whole vehicles at a lower effective tariff rate, creating a competitive disadvantage.

Tariffs on foreign goods, combined with 'Buy America' provisions for a port modernization project, had the unintended effect of massively increasing costs. Even though the project used domestic steel, tariffs on foreign steel allowed U.S. suppliers to raise their prices, contributing to the project's budget ballooning from $400 million to $2.5 billion.

A law requiring the US military to source its clothing domestically provides a crucial, stable revenue stream for American factories. This allows them to stay afloat and produce consumer goods, especially in the technical outdoor gear sector, that would otherwise likely move overseas.

Building hardware compliant with US defense standards (NDAA) presents a major cost hurdle. Marine robotics company CSATS notes that switching from a mass-produced Chinese component to a US-made alternative can increase the price by 8x to 15x, a significant economic challenge for re-shoring manufacturing.

The Jones Act, a protectionist law, mandates that only US-built and crewed ships can transport goods between US ports. This creates bizarre inefficiencies and high costs. Suspending it would immediately improve maritime transport efficiency and lower prices, especially for states like California.

A flat tariff on imports makes complex manufacturing with numerous cross-border steps prohibitively expensive. It becomes cheaper to move domestic production steps out of the tariff zone and import the finished good only once, leading to the deindustrialization of high-skilled jobs.

Flexport's CEO highlights the huge, untapped potential of U.S. river systems for container shipping. Increased trade with Latin America could make New Orleans a premier port, but union contracts prevent the development of this cheaper, greener, and more efficient alternative to road and rail transport.

Companies offshore production because it's cheaper. Forcing manufacturing back to the US via policy results in more expensive or lower-quality goods. While it improves supply chain resilience, this should be viewed as an insurance premium—a cost, not a productive investment.

US policy fetishizes a return to manufacturing, which employs 11% of the workforce. However, protectionist policies like tariffs actively harm the higher-margin, larger tourism industry, which employs 12%. This represents a sclerotic and irrational trade-off that damages a more valuable sector of the economy.
