The challenge

The solution

Requirements

• Define product scope, applications, performance requirements, and critical-to-quality characteristics.
• Specify material type, grade, compound, hardness, color, tolerances, and regulatory needs.
• Identify usage volumes, demand forecast, service levels, and sourcing regions.
• Shortlist suppliers by proven experience in rubber/elastomers for your industry.
• Check manufacturing capabilities: compounding, mixing, molding, extrusion, calendaring, bonding, and testing.
• Verify quality systems: ISO 9001, IATF 16949, ISO 14001, PPAP/APQP, traceability, and SPC.
• Assess raw material sourcing, formulation control, and supply continuity for key polymers, fillers, and additives.
• Review technical support: material selection, design input, prototyping, and troubleshooting.
• Evaluate compliance: REACH, RoHS, FDA, food contact, medical, automotive, fire, and country-specific rules.
• Confirm testing capability: tensile, elongation, compression set, abrasion, aging, ozone, oil/fuel, and temperature resistance.
• Audit capacity, lead times, MOQ, scalability, and contingency plans.
• Assess commercial terms: pricing structure, indexing, payment terms, tooling ownership, and warranty.
• Evaluate logistics: packaging, shelf life, storage conditions, Incoterms, and delivery reliability.
• Run sample approval and validation against performance and fit requirements.
• Complete supplier risk review: financial health, geopolitical exposure, single-source dependency, and business continuity.
• Agree onboarding documentation: specs, drawings, control plans, COA/COC, change notification, and escalation paths.
• Set KPIs: quality ppm, on-time delivery, responsiveness, cost, and claim closure time.
• Define governance: review cadence, scorecards, corrective actions, and continuous improvement plan.

Best practices

• 1. Define exact application requirements: temperature, chemical exposure, pressure, abrasion, UV, ozone, and lifecycle.
• 2. Specify performance rather than generic material names whenever possible.
• 3. Match the elastomer grade to the operating environment and compliance needs.
• 4. Request full material data sheets, test reports, and certifications before purchase.
• 5. Verify supplier quality systems, traceability, and batch consistency.
• 6. Evaluate total cost of ownership, not just unit price.
• 7. Standardize specifications across sites to reduce variation and waste.
• 8. Validate samples and prototypes in real operating conditions before scaling up.
• 9. Confirm dimensional tolerances, hardness, compression set, and other critical properties.
• 10. Check regulatory and industry compliance for safety, food, medical, automotive, or industrial use.
• 11. Assess supplier capacity, lead times, and continuity-of-supply risk.
• 12. Establish clear inspection criteria for incoming goods and acceptance testing.
• 13. Require packaging, storage, and handling guidelines to prevent degradation.
• 14. Build contingency plans for substitutes, alternate sources, and critical inventory.
• 15. Review supplier performance regularly on quality, delivery, responsiveness, and corrective action.
