It has self-operated import and export rights, reports that exports comprise 90% of total sales, and is located in Tianjin with service proximity to Tianjin Port. Its stated service infrastructure is limited: no overseas showroom, agents, branches, or reported offline trade-show participation.

Complaint handling, corrective/preventive action, and approved-supplier-list procedures are not documented in the provided data. Certification, production facilities, customer cases, raw-material traceability, and quality assurance remain unverified.
