SummaryChangsha Weichuang Chemical Co., Ltd. is a China-based limited trading company established in 2007 with nine employees. It offers several chemical products and holds an ISO9001:2015 certificate. Service procedures for corrective actions, customer complaints, supplier approval, and service assessment are documented and followed, while overseas service coverage is absent. The supplier reports ODM, OEM, and sample/design customization capabilities, but no new products were developed in the past year and no SDK is available. Export sales represent 71%–90% of total sales, with self-managed import/export rights, although exporting began only one year ago. Lead times are stated as within 15 working days in both peak and off-season periods. Financial records are identified for 2022–2024, but no financial results are provided. Production capacity, raw-material traceability, and customer-specific cases are not sufficiently documented.

CertificationsThe supplier holds an ISO9001:2015 certificate. A BV audit report is listed with validity from September 30, 2025 to September 29, 2026, but the audit result is recorded as “0” without an explanation of its meaning.

After-Sales capabilityDocumented and followed procedures exist for corrective and preventive actions, customer complaints, supplier approval, and service-capability assessment. However, the supplier has no overseas showroom, overseas agent or branch, or offline trade-show participation, and reports service coverage in zero countries.

R&D capabilityThe supplier reports one year of total R&D-engineer experience, no new product development in the past year, and no available SDK. It does offer ODM services, indicating some design-development support, but the evidence does not demonstrate strong ongoing innovation.
