What is the tariff escalation pattern Why does it exist in many countries?

Tariff escalation refers to the practice of imposing higher tariffs on processed goods compared to raw materials. This pattern exists in many countries to protect domestic industries by encouraging local processing and value addition, thereby fostering job creation and economic development. It can also be a means for governments to generate more revenue from higher-value products. However, such policies can distort trade by making it more expensive for countries to import processed goods.
