I'm going to rephrase your position to make sure I understand it correctly. Please feel free to correct anything I get wrong below.

Tariffs result in higher costs to consumers in the short term due to the additional tax consumers have to pay. This extra tax is harmful to the economy. The reduction in economic growth is deflationary and sufficient to counter inflationary pressure from higher prices on tariffed goods. As a result, tariffs should lead to deflation or have at most a neutral effect on inflation.

Did I sum that up correctly?
