Laboratory testing & Quality Control
When sourcing from Asia—especially for products like food, chemicals, and textiles—quality control is essential. At Topquin, we work with leading European-certified laboratories based in China to ensure your products meet international standards. This helps eliminate the risk of non-compliant, unsafe, or unsuitable goods, protecting your reputation in global markets.
Our testing and inspection services cover every stage of production: from pre-production checks and inspections during manufacturing, to final pre-shipment evaluations, container loading supervision, and even on-site sorting when needed. You’ll have full visibility of your order status and test results throughout the entire process.
Sourcing & Supplier investigation
Access a wide range of qualified suppliers in China. Know your market trajectories, their business models, and human resource management.
Our experience shows that best price is not always the only important indicator; product quality and delivery time are also key factors in a cost-benefit equation. In Topquin Ltd. we focus on companies that can maximize all these variables in order to offer our customers a superior result.
Order Follow-up
Topquin Ltd. has the ability to regularly verify the status of any order. This information is also available to our customers online, 24 hours a day, 7 days a week.
Once an order is entered in our database, Topquin Ltd. regularly updates its status. This tool is very useful to our customers because it provides accurate information about the state of an order. Further, in case a customer has accounts with several factories, this system facilitates their monitoring.
As a result of this system implemented by Topquin Ltd., our customers can be alerted to any problems that stand in risk delivery times.
