consumption and 31 percent of U.S. aluminum consumption (statista) (Bray, 2018) (U.S. Census Bureau,
2015).
In 2017, the U.S. imported USD 27.7 billion of iron and steel products and USD 22.2 billion of aluminum
products. With the exemptions granted to imports from Argentina, Australia, Brazil, and South Korea,
the steel and aluminum tariffs apply to USD 27.8 billion of steel and aluminum imports (U.S.A. Trade
Online). If consumption by industry does not differ across imported and U.S.-sourced steel, and
aluminum, 26 percent of the tariff applied to imported steel and 31 percent of the tariff applied to
imported aluminum becomes a cost increase for the by vehicle and vehicle parts industries. This
approach yields an indirect tax on U.S. auto and auto parts manufacturing equal to USD 1.4 billion. As
higher material costs increase the costs of U.S. manufactured automotive parts, which are used in
vehicles assembled throughout North America, the U.S. tariffs on steel and aluminum impact vehicle
manufacturing in the U.S., Canada, and Mexico. Accounting for North American vehicle parts trade, this
implies a cost increase of 0.43 percent for vehicles assembled in the United States, 0.28 percent for
vehicles assembled in Canada, and 0.15 percent for vehicles assembled in Mexico. Note that these
estimates do not account for retaliatory measures, such as Canada’s tariffs on U.S. steel and aluminum,
nor does CAR consider opportunistic pricing actions taken by U.S. producers of steel and aluminum. As a
result, while CAR’s estimates suggest the steel and aluminum tariffs have added approximately USD 130
per vehicle assembled in North America, Ford and General Motors have each announced $1 billion in
additional costs due to the steel and aluminum tariffs – USD 700 per vehicle produced in North America
(Carey & Shepardson, 2018) (Carey & Klayman, 2018). In announcing 2018 year-end financial results,
Ford’s CFO attributed USD 750 million in increased costs due to tariffs (Klayman, 2019).
Section 301 Tariffs on Imports from China
Review of additional data specific to imported vehicle parts arriving from China suggests that,
specifically for imports from China, far more than this 25 percent share is destined for aftermarket use.
Estimates of the value of Chinese materials used in the production of new vehicles in the United States
were developed, primarily following the “Trade Data Approach.” While total imports of automotive
parts and tooling were valued at USD 15 billion in 2017, many of these items are destined for
aftermarket use (U.S.A. Trade Online). At the 10-digit HS code level, certain products are differentiated
by whether they are new, used, or remanufactured items. Once imports of used or remanufactured
vehicle parts have been removed, the total import value falls below USD 12 billion (U.S.A. Trade Online).
For many of the remaining imports – for example, “wiring sets for vehicles, aircraft, or ships” – use is
split across light vehicle manufacturing, the light aftermarket, and several other industries. For these
items where it is not possible to both identify the appropriate value of content imported for light
vehicles and differentiate between original equipment and aftermarket use, CAR researchers developed
boundary scenarios, considering either the full value of these imports to be used in U.S. light vehicle
production, or all of these imports to be destined for either the aftermarket or non-light vehicle use. The
results of this exercise suggest that between 1 percent and 3 percent of the value of U.S.-assembled
light vehicles stems from parts imported from China. For the evaluation of the potential impacts of
Section 301 tariffs, CAR used the mid-point of this range, 2 percent, as the share of Chinese content in
U.S.-assembled vehicles. With items covered by the first and second tranches of tariffs against import
