The Hidden Data Field That Reveals Unauthorized Sellers on JD.com

JD.com's hybrid retail model—where it fulfills certain products while marketplace merchants handle others—creates a critical blind spot for brands monitoring distribution. The `isJdSelfRun` flag combined with seller type classification provides the cleanest signal for detecting unauthorized resellers, making it essential for brand protection in China's largest e-commerce ecosystem. Without this data intelligence, brands competing on JD.com lack visibility into gray-market activity affecting their pricing and reputation.
