Key Criteria for Selecting a Reliable Enzyme Supplier

Choosing the right supplier goes beyond price—it involves assessing technical capability, operational stability, quality systems, and long-term reliability. Below are essential factors every procurement manager should evaluate.

1. Manufacturer vs. Trader: Prioritize Direct Producers

Always verify whether the supplier is a manufacturer or a trading company. Direct producers typically offer better control over formulation, batch consistency, and customization options. Look for indicators such as factory size, staff count, and R&D investment.

For example, Sunson Industry Group Co., Ltd. employs over 180 personnel and operates a large-scale facility, signaling deep vertical integration. In contrast, newer or smaller entities like TEAM ONE BIOTECH have fewer than 10 employees, indicating potential limitations in scalability.

2. Certifications and Regulatory Compliance

Ensure suppliers meet globally recognized standards:

• GMP (Good Manufacturing Practice): Ensures hygienic and controlled production environments.
• ISO 9001: Validates systematic quality management processes.
• GRAS Status: Required for U.S. market entry; indicates safety for consumption.
• Country-Specific Registrations: Essential for legal import into target markets (e.g., EU Novel Food, Chinese Ministry of Agriculture approvals).

Suppliers like Bivigro Animal Health and Sunson Industry Group hold verified certifications, reducing compliance risk for buyers.

3. Quality Verification Processes

To ensure product efficacy, implement a multi-step verification strategy:

1. Certificate Review: Request up-to-date GMP, ISO, and assay reports.
2. Sample Testing: Conduct third-party lab analysis to confirm enzyme activity levels (e.g., IU/g for cellulase).
3. Production Audits: Schedule virtual or on-site visits to assess fermentation, drying, and packaging lines.
4. Performance Metrics: Analyze historical data such as on-time delivery rates and reorder frequency.

For instance, Bivigro Animal Health Limited boasts a perfect 100% on-time delivery rate and a 22% reorder rate—both strong indicators of customer satisfaction and operational excellence.
