AI-Powered supplier vetting

SummaryShenzhen Etross Telecom Co., Ltd. is a Shenzhen-based limited company with 18 employees, focused on communication equipment and electronic products, including fixed wireless phones and terminals. It reports production capacity of up to 1,000 sets per day, 17 years of export experience, sample-based customization, and R&D activity including new products in the past year and ODM services. Some products are stated to have passed CE, FCC, and RoHS certification, but specific products and certificate records are not provided. Service-control documentation is weak: there are no written procedures or records for corrective actions or complaint handling, and overseas service infrastructure is absent. Financial-related records are identified for 2021–2023, but no substantive financial results are provided. No customer cases are presented.

Supplier typeThe supplier is Shenzhen Etross Telecom Co., Ltd., a combined, privately structured limited company located in Shenzhen, China, with 18 employees. Its licensed scope covers manufacturing communication equipment and electronic products, and it is not identified as part of a larger group.

CertificationsThe company states that some products have passed CE, FCC, and RoHS certification. However, the slices do not identify the certified products or provide certificate details, so the evidence supports stated certification coverage but not comprehensive verification.

After-Sales capabilityThe supplier has no written procedures or records for customer complaint handling or corrective and preventive actions. It also reports no overseas warehouse, showroom, agent, branch, or offline trade-show participation; therefore, documented and international after-sales support appears limited.

R&D capabilityThe supplier reports an R&D center with experienced engineers, new products developed during the past year, and ODM services. It does not provide an SDK and does not serve popular brands through OEM, so innovation capability is demonstrated but limited in the stated areas.

Production capacityThe supplier states production capacity of up to 1,000 sets per day, has listed production and testing equipment, and reports peak- and off-season lead times within 15 working days. Its 18-employee workforce and the absence of further capacity records limit the breadth of verification, but the stated operating capability is positive.

Customization capabilityThe supplier supports customization from samples and provides ODM services, directly indicating both sample-based customization and original design manufacturing capability. No broader customization scope or SDK support is stated.
