Sixty-Eight Per Cent from One Supplier, Through One Port, on One Shipping Route

The managing director of a Caribbean pharmaceutical distributor had built the company into the territory’s second-largest supplier of branded and generic medications to hospitals, pharmacies, and clinics. The business distributed over 1,200 product lines from approximately forty international manufacturers, serving healthcare providers across two Caribbean territories from a single climate-controlled warehouse facility.

The company’s procurement manager had flagged a concern in three consecutive quarterly reports that the managing director had acknowledged but not acted upon: sixty-eight per cent of the company’s product lines, by revenue, were sourced from a single international pharmaceutical manufacturer based in India. The manufacturer produced a broad range of generic medications at competitive prices, maintained the quality certifications that Caribbean regulators required, and had been a reliable supplier for nine years. The relationship was the foundation of the distributor’s competitive positioning — the manufacturer’s pricing and product range enabled the distributor to offer the widest selection at the lowest cost in its market.

The supply chain that connected the manufacturer to the distributor was equally concentrated. Products shipped from the manufacturer’s facility in Gujarat to a consolidation port in Colombo, Sri Lanka, then on a single shipping line’s service to the Caribbean through the Panama Canal. Transit time was approximately twenty-eight days. The distributor maintained approximately six weeks of inventory for fast-moving lines and four weeks for slower-moving products. The inventory buffer had been calculated based on normal transit times and had never been stress-tested against disruption scenarios.

The disruption arrived in three stages across four months, each compounding the impact of the last.

Stage one: the manufacturer experienced a regulatory inspection at its Gujarat facility that identified quality control deficiencies. The Indian pharmaceutical regulator issued a remediation order that required the manufacturer to suspend production of approximately thirty per cent of its product lines until the deficiencies were corrected. The affected lines included fourteen products that were among the distributor’s highest-volume items. The manufacturer estimated a twelve-week production suspension for the affected lines.

Stage two: a major container shipping disruption, triggered by geopolitical tensions affecting a key maritime chokepoint, caused the shipping line that served the manufacturer’s route to reroute vessels around the longer alternative passage. Transit times increased from twenty-eight days to approximately forty-five days. The distributor’s inventory buffer, designed for twenty-eight-day transit times, was insufficient for the extended transit. Products that were in transit took seventeen additional days to arrive, and reorders placed after the disruption would not arrive for six to seven weeks.

Stage three: the combination of the production suspension and the shipping delay created stockouts across the distributor’s product range. Within eight weeks of the initial regulatory action, approximately 340 of the distributor’s 1,200 product lines were out of stock. Hospitals and pharmacies that depended on the distributor for essential medications were forced to source from competitors — competitors who, while smaller, had diversified their supplier base and were not dependent on the same manufacturer or the same shipping route.

The managing director’s attempts to mitigate the crisis were hampered by the concentration that had created it. Alternative manufacturers could not be qualified overnight — pharmaceutical supplier qualification required regulatory approval, quality documentation review, and pricing negotiation that took months. Alternative shipping routes existed but were more expensive and unfamiliar to the company’s logistics team. And the customers who had switched to competitors during the stockout period were not guaranteed to return when supply was restored.

The financial impact over the four-month disruption period: approximately US$3.1 million in lost revenue, US$280,000 in expedited shipping costs for emergency supply through alternative channels, and the permanent loss of three hospital supply contracts that represented approximately eleven per cent of annual revenue. The hospitals that switched cited not just the stockout itself but the distributor’s inability to provide reliable information about when supply would be restored — a communication failure that compounded the supply failure.

The managing director’s post-crisis reflection echoed the procurement manager’s warnings: “We knew we were concentrated. We knew sixty-eight per cent from one supplier was a risk. We chose the risk because the pricing was competitive and the relationship was comfortable. We did not understand that supply chain concentration is not merely a procurement decision. It is a strategic vulnerability that can threaten the enterprise’s survival.”

The Caribbean Supply Chain Vulnerability

Caribbean enterprises operate at the end of supply chains that are among the longest, most concentrated, and most vulnerable in the global economy. The Caribbean’s geographic position — island economies dependent on imported goods, distant from major manufacturing centres, and served by a limited number of shipping routes and carriers — creates structural supply chain risks that Caribbean enterprises must manage proactively.

Import Dependency: Caribbean economies import the vast majority of the goods they consume: food, fuel, pharmaceuticals, building materials, manufactured goods, and the inputs for the industries that drive their economies. This import dependency means that supply chain disruption is not merely an inconvenience — it is a threat to the availability of essential goods and the continuity of business operations. The pharmaceutical distributor’s stockout of essential medications illustrates the human consequence of supply chain concentration in an import-dependent economy.

Shipping Route Concentration: Caribbean territories are served by a limited number of shipping lines operating on a limited number of routes. The concentration of shipping capacity means that disruptions to a single carrier or a single route can affect the availability of goods across entire product categories. The geopolitical shipping disruption that extended the pharmaceutical distributor’s transit times affected not just one enterprise but every importer whose goods travelled through the affected chokepoint.

Supplier Concentration: Caribbean enterprises frequently concentrate their procurement with a small number of suppliers — sometimes a single supplier — because the supplier offers the best combination of price, quality, product range, and willingness to serve the Caribbean market. This concentration is commercially rational in normal conditions but creates catastrophic vulnerability when the supplier experiences disruption. The pharmaceutical distributor’s sixty-eight per cent concentration on a single manufacturer is extreme but not unusual in Caribbean procurement.

Port and Logistics Infrastructure: Caribbean ports and logistics infrastructure have limited redundancy. Most territories have one or two commercial ports, and the capacity of those ports to absorb surge volumes during disruption is constrained. The logistics company in Article 3 of this series experienced the consequences of port concentration directly. Enterprises whose supply chains depend on specific port facilities face concentration risk that extends beyond their own operations to the shared infrastructure they rely upon.

Limited Buffer Capacity: Caribbean enterprises typically maintain minimal inventory buffers because storage is expensive, capital is constrained, and just-in-time practices reduce working capital requirements. These lean inventory strategies work well when supply chains operate normally but provide no cushion when disruptions extend lead times or interrupt supply. The pharmaceutical distributor’s six-week inventory buffer was adequate for twenty-eight-day transit times but insufficient when transit extended to forty-five days.

Supply Chain Risk Assessment: Seeing the Vulnerabilities

Supply chain risk cannot be managed if it is not first made visible. Most Caribbean enterprises have an intuitive understanding of their supply chain dependencies but have never systematically assessed them.

Supplier Concentration Analysis: Map every supplier by the percentage of the enterprise’s procurement it represents, the criticality of the products or services it supplies, and the availability of alternative suppliers. Any supplier representing more than twenty per cent of the enterprise’s procurement, or any supplier that is the sole source for a critical product or service, represents a concentration risk that must be evaluated and mitigated.

Geographic Risk Mapping: Map the geographic origins of the enterprise’s supply chain: where products are manufactured, where they are consolidated, what shipping routes they travel, what ports they transit through, and what geopolitical, regulatory, or natural disaster risks exist at each point. The pharmaceutical distributor’s supply chain traversed India, Sri Lanka, the Panama Canal, and the Caribbean — four geographic risk zones, each with distinct vulnerabilities that the enterprise had never mapped.

Lead Time Stress Testing: Stress-test the enterprise’s inventory buffers against extended lead times. What happens if transit times increase by fifty per cent? By one hundred per cent? What happens if a key supplier suspends production for twelve weeks? What is the inventory runway for each critical product line, and what happens when that runway is exhausted? The pharmaceutical distributor’s inventory buffer had never been stress-tested — a twenty-minute exercise that would have revealed the vulnerability that the four-month disruption exploited.

Single Point of Failure Identification: Identify every point in the supply chain where a single failure would interrupt the flow of goods: a single supplier, a single shipping line, a single port, a single customs broker, a single warehouse, or a single transport provider. Each single point of failure is a vulnerability that supply chain resilience planning must address.

Tier-Two Supplier Risk: The enterprise’s direct suppliers have their own suppliers — the tier-two supply chain that is typically invisible to the enterprise but that can create disruptions that cascade through the supply chain. The pharmaceutical manufacturer’s regulatory issue was a tier-one risk that the distributor could see. But if the manufacturer’s raw material supplier had failed, the disruption would have been equally severe and even less visible. Supply chain risk assessment should extend beyond the enterprise’s direct suppliers to the critical dependencies in the upstream supply chain.

Building Supply Chain Resilience

Supplier Diversification: The most direct mitigation for supplier concentration is diversification: qualifying alternative suppliers who can provide the same or comparable products and services. Diversification does not mean replacing the primary supplier — it means ensuring that the enterprise has qualified alternatives that can be activated when the primary supplier is disrupted. The pharmaceutical distributor’s inability to qualify alternative manufacturers quickly was the direct consequence of never having invested in alternative supplier relationships during normal operations. Supplier diversification is an investment that pays no visible return until disruption occurs — at which point it pays returns that dwarf the investment.

Strategic Inventory Management: For critical products and services, the enterprise should maintain inventory buffers that are calibrated to disruption scenarios, not just normal operating conditions. The buffer calculation should incorporate the stress-tested lead times, the production suspension scenarios, and the time required to activate alternative supply. The additional working capital cost of maintaining a larger buffer for critical items is the insurance premium the enterprise pays for supply continuity.

Logistics Route Diversification: Where feasible, the enterprise should establish relationships with multiple shipping lines, identify alternative shipping routes, and maintain the customs clearance and logistics capability to receive goods through alternative ports. The pharmaceutical distributor’s dependence on a single shipping line through a single route was a concentration risk that logistics diversification would have mitigated.

Supplier Relationship Management: The enterprise should maintain active, informed relationships with its critical suppliers that provide early warning of potential disruptions. The pharmaceutical manufacturer’s regulatory inspection was not a sudden event — regulatory trends and inspection patterns could have been monitored, and the manufacturer could have been asked about its quality assurance processes and regulatory status as part of ongoing supplier management. Enterprises that engage with their suppliers as partners rather than merely as vendors are more likely to receive early warning of potential disruptions.

Contractual Protections: Supply agreements for critical products and services should include provisions that protect the enterprise during disruptions: minimum inventory commitments, production priority during allocation, advance notification of potential supply interruptions, and the right to qualify and maintain alternative suppliers. These contractual protections do not prevent disruptions, but they provide the enterprise with rights and information that improve its ability to respond.

Supply Chain Monitoring: The enterprise should monitor its supply chain continuously for signals of potential disruption: geopolitical developments affecting shipping routes, regulatory actions in supplier countries, natural disaster risks along the supply chain, and the financial health of critical suppliers. Modern supply chain monitoring tools and services provide real-time intelligence on global supply chain risks — intelligence that enables proactive response rather than reactive crisis management.

The Price of Concentration

The fictional pharmaceutical distributor’s US$3.1 million revenue loss and permanent loss of three hospital contracts was not caused by an unforeseeable event. Every element of the disruption was foreseeable: the manufacturer’s regulatory risk was inherent in its operating environment, the shipping route’s geopolitical vulnerability was a known and publicly discussed risk, and the inventory buffer’s inadequacy under extended lead times was a calculation that a single stress test would have revealed.

The managing director’s acknowledgement that the company “chose the risk because the pricing was competitive and the relationship was comfortable” captures the fundamental tension in supply chain risk management: concentration is commercially attractive in the short term and strategically dangerous in the long term. The pricing advantage of a single dominant supplier, the convenience of a single established shipping route, and the simplicity of a single logistics arrangement all create short-term efficiency at the cost of long-term resilience.

Caribbean enterprises cannot eliminate supply chain risk. They operate in an environment where import dependency, geographic distance, and limited infrastructure create structural vulnerabilities that no single enterprise can fully mitigate. But they can manage these risks: through diversification, through strategic inventory, through logistics flexibility, through supplier engagement, and through the continuous monitoring that provides the early warning necessary to respond before disruption becomes crisis.

The cost of supply chain resilience is visible and ongoing. The cost of supply chain fragility is invisible until it materialises — and then it is catastrophic.
