AI-Powered supplier vetting
SummaryQingdao Libang Industry Products Co., Ltd. is identified as a China-based manufacturer/factory and limited company engaged in manufacturing and processing machinery, with a stated product range covering rubber and related equipment. The supplier reports ISO 9001 certification, quality assurance, raw-material traceability, flexible customization, and 90% export sales. Its stated production information is 100 rubber machines annually, with a one-month average lead time in both peak and off-season periods. However, the supplier reports no OEM service for popular brands, no available SDK, no in-stock or overseas warehouse capacity, no overseas agents or branches, and no offline trade-show participation. Quality and supplier-management procedures are partly documented but lack records, while corrective and preventive action procedures are absent. Financial information is limited to year labels without substantive financial metrics, and no customer cases are provided.
Supplier typeThe supplier is described as a manufacturer/factory and limited company in China, engaged in manufacturing and processing machinery. Another record labels it a trading company and states that its scope includes processing, sales, and import/export, indicating a mixed manufacturing and trading profile rather than a purely manufacturing-only structure.
CertificationsThe supplier reports holding ISO 9001 certification. This is explicit evidence of a formal quality-management certification, although no certification scope, issuing body, or validity period is provided.
After-Sales capabilityThe supplier accepts multiple quotation and payment terms and reports a one-month average lead time in both peak and off-season periods. However, it has no overseas warehouse, showroom, overseas agent, or branch, and its complaint-handling procedure has no written records; corrective and preventive action procedures or records are absent.
Production capacityThe supplier is identified as a machinery manufacturer and lists rubber-processing equipment among its products. It reports annual productivity of 100 rubber machines, a one-month average lead time in both seasons, and six total employees in one company-information record; quality staffing is reported inconsistently as either 1 inspector or 6–10 quality-control staff. Production capability is therefore evidenced, but the scale and staffing data require verification.
Customization capabilityThe supplier explicitly offers flexible customization, customization from samples and designs, full customization, and minor customization. These stated service options indicate broad customization coverage for customer requirements.
