President Donald Trump is considering a delay of auto tariffs. A temporary pause won’t be enough for automakers to adjust their vast global supply chains but exemptions on parts could be key to the industry.

Trump imposed 25% car import tariffs in April. Car part tariffs start May 3. Analysts say no car uses all US parts.

The United States' recent protectionist turn – spearheaded by tariffs that former President Donald Trump imposed or threatened on Mexican automotive exports – has cast a long shadow over Mexico's vital auto industry.
