Unironically, depending on how the supply chain is arranged for your industry, it may actually be cheaper to move your manufacturing off shore and eat the tariff once instead of getting nickeled and dimed for every single item you need to assemble on shore.

And that's not even accounting for forecasting, which is still necessary in the stupid-frail JIT approach. Noone will want to sign a long-term supply contract when they could get screwed by sudden tarrifs and the JIT people have to rely on luck to avoid subjecting customers to sticker-price whiplash.

It's all just so fucking stupid.

Edit: Not sure what my auto-correct meant there. To be clear I was intending to state that JIT logistics is stupidly frail because it is unable to smooth out uncertainties in supply chains and a single distribution or price swing in a necessary component can result in the material costs of the product going so high that the business either has to sell at unpredictable prices, eat the difference, or set the base price higher and pocket the difference when favorable.
