AI-Powered supplier vetting

SummaryJilin Carbon New Material Co., Ltd. is a China-based combined business entity established in 2023, with 16 employees and one production line. It reports annual calcined petroleum coke productivity of 40,000 tons and indicates quality assurance, raw-material traceability, R&D activity, ODM services, OEM experience for well-known brands, and broad customization capabilities. However, the supplier has one listed quality assurance and quality control inspector, lacks written records for finished-product inspections and corrective actions, and has no written complaint-handling procedures or records. No valid manufacturing-capacity contract with affiliated subcontractors, inventory capability, overseas warehouse, overseas showroom, overseas agent or branch, or offline trade-show participation is reported. Financial records are identified for 2021–2023, but their results are not provided. Environmental and fire-drill status is unknown.

After-Sales capabilityThe supplier supports multiple quotation and payment terms and reports lead times of within 15 workdays off-season and one month during peak season. However, it has no overseas agents or branches, warehouses, showrooms, or inventory capability, and its complaint-handling process has no written procedures or records; corrective-action procedures also lack written records.

R&D capabilityThe supplier reports a new product during the past year, provides ODM services, and has OEM capability for popular brands. It also reports one R&D engineer with total experience information, while SDK availability is explicitly absent; the evidence supports product-development and design capability but not SDK-based development.

Production capacityThe supplier reports one production line and annual calcined petroleum coke productivity of 40,000 tons, with stated peak-season and off-season lead times. However, it has no inventory capability and no valid manufacturing-capacity contract with affiliated subcontractors, which limits the evidence for broader capacity flexibility and control.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its ODM and OEM capabilities further support the stated ability to provide customized product development and manufacturing.
