How critical it is to rely only on one country for critical supplies?

Relying on a single country (e.g. China) for critical supplies is a concentration risk. Recent years have shown how quickly conditions can change, with policy shifts, tariff swings, border slowdowns, and health emergencies (e.g. COVID) disrupting otherwise stable plans. The next disruption could arrive with little notice (new escalations and wars are increasing every year), and cost, lead time, and compliance can all shift at once. The answer is not the cheapest quote; it is risk management: qualify backup suppliers in multiple markets, dual-source key SKUs, mirror quality and testing, secure alternative logistics lanes, and keep continuity plans ready. Diversify now to protect timelines and margins, and to keep operations running when the environment shifts again.
