Treat the two risks separately, because they are mitigated by different things. Logistics risk is concentration risk: a single supplier, a single port or a single corridor is one disruption away from stopping your supply, so dual-source critical lines across two countries, keep buffer stock on anything with a long lead time, and model corridor reliability rather than only freight price — a cheaper quote out of a congested corridor is not cheaper once demurrage lands. Payment risk is exposure risk: every method decides who is exposed while goods are in transit, so use funds held until confirmed delivery for first orders, stagger payments across suppliers so no single failure takes a whole cycle, fix one settlement currency across quotes rather than comparing across an exchange rate you have not fixed, and require a second approver above a threshold you set. Two disciplines cut across both: keep documentation identical in structure between countries, since a per-country improvisation is where errors enter; and record every duty assumption with its HS code and the date it was checked, because tariff schedules change and AGOA runs to 31 December 2026 with a Senate-passed extension to 31 December 2028 still awaiting the House. Verify each counterparty independently in its own national registry — a supplier being reliable in one country tells you nothing about a different company in another.
