Supplier typeThe supplier is identified as Qingdao Stone Rubber Products Co., Ltd., a China-based limited company established in 2004. Its stated product scope covers PU and rubber wheels, carts, wagons, electric wheelbarrows, mini dumpers, and wheel chocks, indicating a combined manufacturing and export-oriented supplier profile.

CertificationsThe supplier reports holding an ISO9001:2015 certificate. This is explicit certification evidence, although no additional certification details are provided.

After-Sales capabilityThe supplier has written procedures and followed records for customer complaint handling, corrective and preventive actions, and service-capability assessment. However, it has no overseas warehouse, showroom, agent, or branch, while its stated peak- and off-season lead times are both one month.

R&D capabilityThe supplier reports new products within the past year and provides ODM services, demonstrating product-development activity. However, it reports no available SDK, so the evidence supports general R&D capability but not SDK-based innovation support.
