Each product sold by our company has a unique traceability code, which can be identified and traced back to the production batch, time, incoming batch, testing records and other information. Our products are independently developed and designed, and 90% of the products are exported under our own brand. The appearance, labels and packaging of the products are all recognizable by the TOPSFLO Logo. Our products have their own unique design features, and are mainly for the middle and high-end market, which can be easily identified from the appearance and performance of product parts.
