What makes us special?

Some Asian-based service providers try to do a little bit of everything and end up not doing any one thing particularly well. At TOPWIN, we focus exclusively on Quality Control services (audits, inspections and testing) and nothing else. This specialization allows us to ensure that our inspectors are screened, well trained and regularly monitored. Our on-line client support and project management system sets the industry benchmark. We are fully committed to ensuring Quality and Customer Satisfaction by collecting accurate information at the factory floor.
