Supplier typeThe supplier is a limited company with eight employees and is classified as both a trading company and manufacturer/factory. Its primary offered product is chemical, and its stated location is Qingdao, Shandong, China.

CertificationsThe supplier reports ISO 9001 certification and an SGS audit conducted from July 18, 2024 to July 17, 2025. However, the audit evaluation is recorded as “0” without an accompanying interpretation, so the SGS result cannot be treated as a positive qualification.

After-Sales capabilityThe supplier states that it has a clear customer-complaint procedure with follow-up records, provides professional after-sales service, and aims to provide solutions or responses within 24 hours of inquiries. These statements provide explicit evidence of an established service process.

R&D capabilityThe supplier has no available SDK and reports one R&D engineer. These facts indicate limited documented development resources, while no broader evidence of product innovation or technical development capability is provided.

Customization capabilityThe supplier explicitly describes its design-service capability as flexible customization. This directly supports the presence of customization capability, although the scope, technical process, and limits of customization are not specified.
