Really the risk sounds more like a job for insurance and warranties tied to product specs than tarrifs.

I don't see a connection between tarrifs and risk in a supply chain. Infamously US autos which refused to adopt Tailorism or other cousin methodologies for reliability wound up being expensive crap compared to Japanese car makers. It is a peripheral variable at best or an irrelevant one at worst.

Tarriffs as a solutio resemble opportunistic timing to not let a crisis go to waste rather than addressing a root cause.
