AI-Powered supplier vetting

SummaryHenan Fireramo Industrial Co., Ltd. is a China-based limited company operating as both a trading company and manufacturer/factory, supplying refractory bricks, refractories, castables, fire bricks, and fire mortar. It reports broad customization and ODM/OEM services, but no new products in the past year and no available SDK. The supplier states that its personnel have more than 30 years of industry experience and maintains technical cooperation relationships with refractory and steel research organizations. However, evidence of formal service-management procedures is weak: no written procedures or records were provided for supplier assessment, corrective actions, or complaint handling. The supplier has no overseas warehouse, showroom, agents, or branches, although it has participated in a 2025 offline trade exhibition. Audit information identifies CTI as the auditing organization, with a report covering January 2026 to January 2027, but the stated audit evaluation result is 0.

Supplier typeThe supplier is identified as both a trading company and manufacturer/factory, organized as a limited company in Henan, China. Its stated business scope includes refractory-material sales and related technical services, while its product scope covers refractory bricks, refractories, castables, fire mortar, and related items.

After-Sales capabilityThe supplier reports no written procedures or records for effective complaint handling, service-capability assessment, or corrective and preventive actions. It also has no overseas warehouse, showroom, agents, or branches; its stated service support is therefore limited in the provided evidence, despite accepting several quotation and payment terms and reporting a one-month lead time in both peak and off-season periods.

Customization capabilityThe supplier explicitly reports customization from samples, designs, full customization, minor customization, and flexible customization. It also states that ODM services are available, providing direct evidence of broad customization support.

Client casesThe supplier reports providing OEM services for well-known brands and describes technical cooperation with Luoyang Institute of Refractories Research Co., Ltd., an Iron and Steel Research Institute, and Chongqing Iron and Steel Co., Ltd. These statements indicate named business or cooperation references, but no detailed customer projects, order results, or independently verified case outcomes are provided.
