No, the purpose of tariffs is to make domestically-produced goods cheaper than imported goods, not to raise the price for the consumer.

How exactly do you make local prices decrease by making imported goods more expensive? It does not make any sense. If the global market price of a product get artificial higher, one do not lower the local prices. The local prices get increased to match what ever the effective global market price (price + tariff) is.

Of course. The purpose of tariffs is neither to increase nor lower the prices of goods. The purpose of tariffs from the government point of view is to increase self-production, value generating, and self-sustainability. But the practical effect of an tariff is a higher priced product for the consumer. In the word of wikipedia: Typical analyses find that tariffs tend to benefit domestic producers and government at the expense of consumers.
