Supplier typeThe supplier is identified as a limited company with a combined company type. Its stated business scope covers manufacturing, processing, and sales of valves, flanges, and accessories, plus import and export activities, while its offered product scope is valves and flanges.

CertificationsThe supplier states that it holds API 6D, API 607/6FA fire, and TÜV SIL functional safety certifications. It also reports participation in national standard formulation and drafting 13 industry standards, but the certification evidence is limited to the stated company description.

After-Sales capabilityThe supplier reports no overseas warehouse, showroom, overseas agent, or branch, and indicates zero countries with overseas services. It has a customer-complaint handling procedure, but no written records, so the available evidence does not demonstrate strong after-sales execution.

Production capacityThe supplier reports six production lines and a one-month average lead time in both peak and off-season, with 15 experienced export staff supporting trade operations. Against this, it reports no inventory capability and no valid manufacturing contract with related subcontractors, so production capacity is evidenced but operational resilience has stated gaps.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, and flexible customization, and also provides ODM and OEM services, including OEM service for well-known brands. It does not provide 3D software design services, but the stated manufacturing and customization options support a positive assessment.
