AI-Powered supplier vetting

SummaryShenzhen Ansorl Technology Co., Ltd. is a China-based trading company established in 2016, focused on security and fire-protection products. It reports 90% export sales, self-operated import and export rights, and exports beginning in 2006. The supplier lists seven production lines, two R&D engineers, six to ten quality-control staff, a 120.0 m² manufacturing area, and stated standard-item delivery within 15 working days in off-peak periods and one month during peak periods. Its description mentions ODM services, product upgrades, a 12-month warranty, and multiple delivery terms. However, the certification information is recorded only as “Others,” and the available trade records show limited documented transactions with one named buyer. Financial strength cannot be assessed because monetary figures are excluded from this analysis.

Supplier typeThe supplier is explicitly identified as a trading company and a limited company, operating from Shenzhen, Guangdong, China. This supports classification as a trading-oriented supplier rather than a clearly documented manufacturer.

After-Sales capabilityThe supplier explicitly states a 12-month warranty guarantee and welcomes customer inquiries and visits. This provides evidence of a stated warranty and customer-support commitment, although no detailed service process or support coverage is given.

Production capacityThe supplier reports a 120.0 m² manufacturing area, seven production lines, six to ten quality-control staff, and stated delivery capacity of within 15 working days off-peak and one month during peak season. These figures support an operational production capability, although the supplier is classified as a trading company and production scale is relatively limited in the provided record.

Customization capabilityThe company description explicitly offers ODM services and states that it can handle other customer requests. This directly supports customization capability, though no details are provided about engineering scope, tooling, or minimum order requirements.

Client casesTrade records identify AGNI DEVICES PRIVATE LIMITED as a buyer for CO detectors, heat detectors, and standalone smoke detectors, with records dated February and August 2025. This confirms at least one documented customer relationship and product-related transactions, but the narrow buyer base and limited transaction count provide only modest case evidence.
