This is not correct. The cost of tariffs are shared by the distributor and customer. The proportion is determined by the elasticity of demand. By this I mean that for goods and services which people rely on, like gas, they will pay almost all of the cost of the tariff because they need the gas to survive. For luxury goods and services, like Louboutin shoes, most of the cost of tariffs is paid by the distributor. This is because customers are willing to substitute for other options, or simply not buy that item. They don't need it.

The downstream effects are quite complex to calculate. For this reason, neoliberals prefer to avoid any tariffs at all. For example, the U.S. is a net gas exporter, meaning that total net local consumption can be satisfied without imports. In a perfect market, there would be no change to the cost of gas. However gas is a commodity, and there is the risk that cartels abuse their market positions to exploit the fact that locals must buy gas from them if they wish to avoid the tariff. For other goods like imported food, locals can substitute. They don't have to buy imported avocados. There are plenty of other affordable and nutritious foods available locally. However, the loss of avocados is, by some metric, a loss of quality of life. This isn't generally captured in economic data. Further still, some of these additional costs are offset by the fact that local businesses become more profitable thanks to said tariffs, and this ends up in the pockets of consumers. Because so much menial labour is currently offshored, the primary benefactor of tariffs is expected to be the poor and working classes.
