Humanitarian supply chain: strategic procurement, stock and total cost

1Why the supply chain is a leadership issue

It is commonly estimated that logistics and procurement account for a major share of humanitarian spending, often cited at around 60 to 80% (van Wassenhove, 2006). A 5% gain on that spending is often worth more than all efforts to cut headquarters costs. The supply chain also determines the speed of the response, the quality of the aid and a large part of the fraud risks.

The central tension is speed versus cost: emergency air freight often costs 5 to 10 times more than sea freight, but delivers in days instead of weeks. Leaders must set the rules of the game in advance: which categories are prepositioned, when air freight is justified, which lead times are acceptable for each type of intervention.

Key indicators to track at country level: processing time of purchase requests (from request to delivery), on-time in-full delivery rate, share of purchases under framework agreements, stock turnover and expiry, logistics cost per tonne delivered and the compliance rate of procurement files at audit.

2Procurement strategy: Kraljic and framework agreements

The Kraljic matrix (1983) classifies purchasing categories by their financial impact and their supply risk:

Framework agreements are the most powerful tool for reconciling speed and compliance: competition takes place once, in advance, and orders are then placed within a few days during the crisis. Donor procedures (for example the rules applicable to the European Commission's humanitarian partners, or the thresholds set by each organisation) provide thresholds above which the procedure becomes heavier: direct purchase, consultation of several suppliers, local open tender, then international tender. They also provide emergency procedures (justified direct negotiation), which must be documented with a waiver note.

For the manager: every waiver from the normal procedure must be justified in writing, approved at the right level and filed. A real but undocumented emergency becomes, at audit, an ineligible cost.

3Stock management: formulas and decisions

Three calculations cover most stock decisions:

• Safety stock (simple approach): average daily consumption × lead-time margin, or more precisely z × standard deviation of demand during the replenishment lead time.
• Reorder point = average daily consumption × replenishment lead time + safety stock.
• Economic order quantity (Wilson formula): EOQ = √(2 × D × S / H), where D is annual demand, S the fixed cost of an order and H the annual cost of storing one unit.

Example. A nutrition programme consumes 40 cartons of therapeutic food per day. The replenishment lead time is 60 days; a safety stock of 20 days of consumption is chosen. Reorder point = 40 × 60 + 40 × 20 = 2,400 + 800 = 3,200 cartons: as soon as stock reaches 3,200 cartons, an order must be placed. If the lead time rises to 90 days because of a port disruption, the reorder point rises to 40 × 90 + 800 = 4,400 cartons.

The FEFO rule (first expired, first out) is a must for medicines and food. Physical inventories must be at least quarterly, and unannounced for sensitive stock, with reconciliation against stock cards and the system.

4Transport, Incoterms and total cost of ownership

The total cost of ownership (TCO) adds to the purchase price all costs up to use: transport, insurance, duties and taxes (often waived for registered NGOs, but with administrative delays), storage, losses, maintenance and disposal. A cheaper international supplier can cost more than a local supplier once all costs and lead times are counted; conversely, a local product of insufficient quality is costly in losses and reputational damage.

The International Chamber of Commerce's Incoterms 2020 define how costs and risks are shared between seller and buyer. The most used: EXW (the buyer takes charge of everything from the factory), FCA (the seller hands the goods, cleared for export, to the carrier named by the buyer), CIF (the seller pays freight and insurance to the port of destination, but risk passes to the buyer at loading), DAP (delivered at the agreed place, not cleared for import), DDP (delivered cleared, duties paid). Choosing the wrong Incoterm can leave the NGO carrying a risk it thought had been transferred.

TCO example. 10,000 tarpaulins: international offer at USD 9.50 per unit FCA, plus USD 2.80 freight and insurance, USD 1.20 clearance and inland transport, lead time 10 weeks; regional offer at USD 12.60 delivered DAP warehouse, lead time 3 weeks. International TCO: USD 13.50; regional: USD 12.60 plus about USD 0.40 clearance = USD 13.00. The regional offer is cheaper and faster, provided that quality meets the specifications (inspection and samples).

5Risks, localisation and sustainability of the supply chain

Mapping supply chain risks covers: dependence on a single supplier or corridor, price and exchange-rate volatility, road insecurity, import restrictions, seasonal access and fraud. The responses: several qualified suppliers, alternative corridors, regional prepositioning, indexation clauses, insurance, and coordination through the Logistics Cluster (information sharing on access, common transport and storage services).

Cash transfers shift part of the supply chain to local markets: the decision is made with a market analysis (traders' capacity to absorb demand, integration, prices) and continuous price monitoring. They do not remove risks: they shift them to payment providers and data protection.

Environmental sustainability is becoming a donor requirement: the Climate and Environment Charter for Humanitarian Organizations (2021) commits signatories to reducing their emissions, particularly from transport and procurement. Levers: prefer quality local or regional purchases, reduce air freight through prepositioning, reduce packaging, manage waste and plastics, and choose more durable products.
