Supplier typeThe supplier is explicitly described as both a trading company and manufacturer/factory, while its industry is identified as manufacturing and its listed products and factory location support manufacturing involvement. However, one record also classifies the company nature as a trading company, indicating a mixed or inconsistent classification.

CertificationsThe supplier explicitly states that it holds ISO 9001:2015 and API certificates, and ISO 9001 is separately listed under supplier management-system certification. This provides direct evidence of formal quality-management certification and an API-related certification claim.

R&D capabilityThe supplier describes itself as an enterprise integrating science and technology, offers technical solutions, and reports 6–10 R&D engineers with fluid-sealing technology expertise. These statements support the existence of R&D capability, although no specific patents, new-product records, or measurable innovation outcomes are provided.

These details directly support substantial production capacity, though the full annual capacity for some products is not specified.
