The pandemic exposed the fragility of single-supplier supply chains for businesses of every size. Supplier concentration is a risk that needs to be managed deliberately.

Assess Your Current Concentration

Map what percentage of your product cost comes from each supplier. If any single supplier represents more than 50% of COGS, you have a concentration risk that warrants attention.

Develop Backup Suppliers for Key SKUs

For your top-selling SKUs, identify at least one backup supplier who can produce to your specifications. Qualify them through a sample process and understand their lead times, MOQs, and pricing.

Geographic Diversification

Single-country manufacturing creates geopolitical and logistical concentration risk. Developing relationships with suppliers in alternative countries — even for a portion of volume — provides optionality when tariffs or disruptions affect your primary source.

The fix: Identify your top three SKUs by revenue. For each, confirm whether you have a qualified backup supplier. If not, make qualifying one a Q1 priority.

Map where the business is actually concentrated

Review spend, units, revenue dependency and lead time by supplier, factory, country and critical component. Two suppliers are not true diversification if they rely on the same upstream source or logistics route.

Prioritize the risks worth diversifying

Consider single-source components, long tooling lead times, geopolitical exposure, capacity limits, quality instability and products with no practical substitute. Diversification has cost, so start where a disruption would materially affect the business.

Qualify the backup before you need it

Collect specifications, samples, quality expectations, commercial terms, capacity information and lead-time assumptions. A supplier that has never produced or shipped the product is not yet a usable contingency.

Decide how to keep the alternative viable

Some businesses split ongoing volume; others maintain tooling, approved samples or a contingency agreement. Document what must stay current so the backup does not become obsolete.

Create a supplier-risk scorecard

Score critical suppliers on concentration, lead-time variability, quality history, financial exposure, geography, tooling ownership and substitutability. Use the score to decide which relationships need contingency work first.

Document transfer requirements

For products that may need a second source, identify tooling, specifications, approved materials, testing, certifications and packaging assets that would be required to move production. Diversification is much faster when those dependencies are known in advance.

Estimate the cost of diversification

Second sources can require tooling, qualification, smaller production runs, duplicate packaging or more complex planning. Compare that cost with the financial impact of a plausible disruption to the primary source.

Protect intellectual property and specifications

Know who owns tooling, artwork, molds, test methods and product files. A backup supplier is less useful if critical assets cannot legally or practically be transferred.

Run a readiness test

Periodically confirm that backup contacts, capacity assumptions and specifications are still current. A supplier qualified two years ago may no longer have the same materials, lead time or commercial terms.

Use diversification selectively

Critical high-margin products may justify dual sourcing, while low-volume items may be better protected with safety stock or alternative products. Match the strategy to the risk.
