To ensure supplier credibility, prioritize those with established industry certifications such as ISO 9001, IEC-60317 compliance, UL certification, and RoHS adherence. Request detailed company profiles, including production capacity, export history, and client references in your region. Conduct virtual audits or request factory visits if feasible. Additionally, review third-party inspection reports and customer testimonials. Engaging with suppliers who participate in international trade associations or have long-standing market presence reduces risks, ensuring product quality and reliable delivery for your projects.
