QUALITY ASSURANCE
To avoid "no-return" damages to the supply project, the risks should be estimated so carefully and characterized in detail. Thus, importance of such quality-based approach makes a comprehensive quality management compulsory, not only for the production but also for the loading and shipment as well. Specifically determining the most appropriate production plan, inspiring our manufacturer partners to innovation and common senses for caring about the quality.Appointing (independent) "third party inspection" (TPI) organizations and coordinating the inspection plan of the production and loading steps.
These all assure the premium quality of our strategically project management.
