AI-Powered supplier vetting

SummaryHricc Industrial Equipment (Shandong) Co., Ltd. is a China-based combined company established in 2023 with five employees. It reports manufacturing equipment including laser cutting, shearing, painting, bending, shot blasting, laser welding, drilling, and milling machines, along with 100% finished-product inspection and one quality inspector. The supplier states that it provides OEM services for popular brands and offers broad customization, but it has no SDK availability. Service support includes inventory capability, multiple quotation and payment terms, and stated lead times of within 15 working days in both peak and off-season periods. However, it has no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse, showroom, agent, branch, or offline trade-show participation.

After-Sales capabilityThe supplier describes a pre-sale and after-sales service system and reports inventory capability, written service procedures with follow-up records, and lead times within 15 working days in both peak and off-season. Conversely, it has no overseas warehouse, showroom, agent, branch, or overseas-service coverage, limiting the evidence for localized after-sales support.

Production capacityManufacturing resources include laser cutting, shearing, painting, bending, shot blasting, laser welding, drilling, and milling equipment. The supplier reports 100% finished-product inspection, one quality inspector, inventory capability, and lead times within 15 working days; however, it has no valid contract with related subcontractors, which creates a documented manufacturing-management limitation.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, minor customization, full customization, and flexible customization. This directly supports a broad customization range.

Client casesThe supplier states that it provides OEM services for popular brands and has customers in more than 100 countries and regions, listing examples including the United Kingdom, France, Italy, Spain, South Africa, Japan, and South Korea. These are supplier-provided claims, and no named customer identities, project details, or independently verifiable case documentation are included.
