(CNN) President Donald Trump wants to give America's farmers $12 billion to shield them from losses in his global trade feuds. But if he bailed out every industry affected, it would cost more than triple that, a new report found.

Providing aid to all US sectors hurt by other countries' retaliatory tariffs would cost $39 billion, according to the US Chamber of Commerce.

Auto part manufacturers would receive $7.6 billion, and iron and steel producers would get $4.6 billion. An array of other industries — from fishing to furniture-making — would also need multimillion-dollar packages.

The chamber's analysis was prompted by the Trump administration's announcement last week that it would provide up to $12 billion in aid to certain farmers, dairy and pork producers.

Several key US trading partners, including China, Canada, Mexico and the European Union, have levied tariffs on a variety of agricultural products in response to Trump administration tariffs on their exports.
