President Donald Trump's tariffs on America's three largest trading partners have led to questions about how tariffs work and who pays for them when goods are imported.
One reason governments use tariffs is to protect domestic industries. However, tariffs can have downsides, including reducing the purchasing power of consumers.
Tariffs typically come in the form of taxes or duties levied on importers, and they're eventually passed on to consumers. They're commonly used in international trade as a protectionist measure.
