A 25% tariff being considered on vehicles and auto parts imported to the US would be broadly credit negative for the global auto industry, Moody's Investors Service said in a report.

"Tariffs on imported vehicles and parts would be negative for nearly every group in the industry — automakers, parts suppliers, car dealers and even transportation companies – as it rippled across the globalised supply chain, which we forecast will produce about 96.7m light vehicles this year," said Moody's senior vice president Bruce Clark.

US automakers Ford and GM are vulnerable to import tariffs, as both import a significant number of vehicles into the US. GM in particular depends on imports from Mexico and Canada to support its US operations (30% of its US unit sales compared to Ford's 20%), and sources a significant portion of its high-margin trucks and SUVs from those two countries.

"Both GM and Ford would need to absorb the cost of scaling back Mexican and Canadian production and shifting some back to the US," noted Clark.

"They would also likely need to subsidise sales to offset the tariffs during the near term, and could eventually pass on the higher costs to consumers."

Moody's said non-US auto manufacturers would suffer even more from tariffs than their US counterparts. European automakers without US plants, for example, including Jaguar Land Rover, would be hit particularly hard.

Japanese carmakers that export a meaningful proportion of domestically produced cars to the US, such as Toyota (22%) and Nissan (31%), would need to significantly adjust their production.

Korean automakers Hyundai and Kia Motors' plans to increase US production and reduce imports will be insufficient to fully offset the potential negative effects of tariffs.

Chinese auto manufacturers, on the other hand, have minimal exports and thus will be largely unaffected.

Meanwhile, a 25% tariff would hurt both Mexico's car production and the country's economy as a whole, as numerous automakers have built assembly
plants in Mexico to service the US market, resulting in the auto industry representing 2.9% of Mexico's GDP in 1Q 2018.

Major auto parts manufacturers could struggle to adjust to supply chain shifts resulting from tariffs, noted Moody's.

Suppliers' efforts to optimise production cost and time for completed parts often results in multiple cross-border trips for finished goods which could incur multiple tariff charges, and avoiding those costs could disrupt the supply chain.

On the retail side, US auto dealers, which are typically heavily weighted towards imports, would also suffer significantly. Auto-parts retailers, however, would generally be unaffected as they are insulated by replacement part demand for the 260m vehicles currently on the road.
