• Check if they hold patents or proprietary technology.

Certifications and Compliance Standards

Ensure your supplier meets international benchmarks such as ISO 9001 (quality management), CE (European safety), and food-grade certifications (e.g., 304/316 stainless steel usage). These validate not only safety but also durability under continuous use.

Suppliers like Henan Kunteng Machinery Manufacturing Co., Ltd. often highlight these credentials prominently, signaling commitment to export-quality standards.

Production Capacity and Scalability

Assess whether the supplier can meet current and future volume demands. Key indicators include:

• Factory size (e.g., Foshan Ike’s 59,000 m² plant supports large batch orders)
• On-time delivery rate (aim for ≥97%)
• Reorder rate (high rates indicate customer retention)

Price Comparison and Value Analysis Among Top Suppliers

While upfront cost is a consideration, total value—including after-sales service, spare parts availability, and energy efficiency—should drive decision-making.
