How Tariffs Actually Work
Who pays them, how they move through supply chains, and why the effects can show up far from the border.
The basic mechanism
A tariff is a tax imposed on imported goods. The importer generally pays the tariff when the goods enter the country, but the economic cost can be shared across importers, suppliers, retailers and customers depending on market conditions.
Why prices may change
Companies may absorb part of the cost, negotiate lower supplier prices, switch suppliers, reduce margins or raise customer prices. Different products therefore respond differently to the same tariff rate.
Why governments use tariffs
Tariffs can be used to protect domestic industries, raise revenue, respond to another country's trade practices or create leverage in negotiations. They can also trigger retaliation or shift trade toward other countries.
