After all, it is the US consumer that is paying for all the envro regs & monitoring as well as the ports for shipping (channel dredging), etc. w/ our domestic consumption.
Taxes and tariffs charged on both ends of any transaction are determined by the applicable trade agreement with the receiving country. If any product is so burdened with additional taxes then all products should be so burdened; or so any lawsuit would hold. The cost of regulatory compliance is built into the products (including gas) as an expense. To that extent they are represented in the export price. But if tomatoes are exported from the same port, should they not also be subject to a dredging tax?
Additional taxes would interfere with existing trade agreements and the ramifications would be far ranging. Why not tax oranges and tomato exports because they must also use roads and follow environmental regulations? Would this not drive down the price of oranges and tomatoes?
Im in favor of letting the market work. The freer the market the lower the consumer price.
