This reflects the company’s ability to continuously serve customers in the future.

4. Supply Chain and Delivery Capabilities

Even the best products cannot sustain long-term cooperation if they cannot be delivered on time.

4.1 Inventory Management

Focus on:

• Safety stock level
• Raw material reserve capacity
• Finished product inventory turnover rate

Reasonable inventory can reduce the risk of stockouts.

4.2 Delivery Cycle

Key areas to consider:

• Standard product delivery time
• Customized product delivery time
• Emergency order response capability

Mature suppliers typically have clear delivery commitments.

4.3 Logistics System

Understand their:

• Domestic transportation network
• International export experience
• Port resources
• Logistics partners

For export-oriented customers, international logistics experience is crucial.

4.4 Risk Management Capability

Assess whether the supplier possesses:

• Multi-channel raw material procurement system
• Emergency production plan
• Energy security plan
• Contingency response mechanism

This determines their supply stability during periods of market volatility.

5. Industry Experience and Customer Cases

Long-term cooperation is often built on rich industry experience.

5.1 Service Industry Coverage

Understand whether the supplier has served:

• Packaging industry
• Film industry
• Injection molding industry
• Pipe industry
• Automotive industry
• Home appliance industry

The more extensive the industry experience, the better the understanding of customer needs.

5.2 Key Client Cases

During the audit, you may request to know:

• Scale of cooperating clients
• Years of cooperation
• Product application cases

Long-term service to well-known clients usually indicates that their products and services have been validated by the market.

5.3 Customer Satisfaction

This can be assessed through the following methods:

• Client testimonials
• Third-party evaluations
• Client follow-up records

This information helps determine the supplier’s true service level.

6. Service and Communication Capabilities

Suppliers should not only provide products but also become technical partners to their clients.

6.1 Technical Service Capabilities

Excellent masterbatch manufacturers should be able to provide:

• Formula optimization suggestions
• Processing parameter guidance
• Product application support
• On-site technical services

Helping clients reduce production costs and improve product performance.

6.2 Response Speed

Focus on:

• Pre-sales response time
• Efficiency of technical consultation response
• Quality complaint handling time
