AI-Powered supplier vetting

SummaryShenzhen Okerda Technology Co., Ltd. is identified as both a trading company and manufacturer/factory in Shenzhen, China, supplying electronic components including transformers, inductors, power supplies, Litz wire, motors, UPS products, adapters, and chargers. It reports more than 10 production lines, exports to a broad range of global markets, and has exported since 2005, with exports representing 71%–90% of total sales. ISO 9001 and ISO 14001 certifications are stated, while the company background also references ISO 45001. The supplier states that OEM orders are welcome and describes custom production of transformers and inductors. However, many operational, service, traceability, audit-result, and customer-reference fields are marked unknown, limiting verification of several capabilities.
Supplier typeThe supplier is described as a trading company in its company profile and as both a trading company and manufacturer/factory in its entity classification. Its Shenzhen address and stated manufacturing activities support a mixed trading-and-manufacturing profile.
CertificationsISO 9001 and ISO 14001 are explicitly listed, and the company background additionally states ISO 45001 certification. An SGS audit is recorded with a validity period from April 8, 2025 to April 7, 2026, but the audit evaluation result is coded as “0,” so the detailed audit outcome cannot be interpreted from the provided data.
Production capacityThe supplier reports more than 10 production lines, off-peak lead times within 15 working days, and peak-season fulfillment within one month. Its classification as both trading company and manufacturer/factory supports production involvement, although actual capacity and output figures are not independently verified here.
Customization capabilityThe company states that it offers custom production of transformers and inductors and welcomes OEM orders. This is direct evidence of customization and OEM willingness for at least these product categories.
