Another upgrade! The United States announced that it will raise the tariff rate on Chinese goods imported into the US from 84% to 125%! In the face of the "tariff war" launched by the United States, China has adopted equivalent retaliatory tariffs and a series of countermeasures, raising the tariff rate on imported goods from the US from 34% to 84% 。

Many companies in the IVD industry rely on imported raw materials and equipment. The further escalation of this tariff policy will have the most direct impact on the IVD industry, which is the production cost of reagents may double. The surge in costs will not only reduce the short-term profit margins of enterprises, but will also weaken their market competitiveness.

Shouldering responsibility, staying calm in the face of challenges >>

In recent years, China has introduced a number of policies to support the development of the IVD industry and accelerate the process of domestic substitution. Liding Medical has always adhered to independent innovation, dared to break through technological barriers, and successfully built an independent R&D and production system for core raw materials such as nano-microspheres, natural antigens, and antibodies 。

At the same time, market verification shows that choosing Liding Medical's independently developed nano-microspheres as a substitute for imports can help reduce reagent production costs by more than 70%, and significantly enhance the market competitiveness of enterprises.

Liding Medical solemnly promises: In the face of fluctuations in US-China tariffs, prices of all products remain stable ! We will work alongside our IVD industry partners to share the pressure, optimize costs and empower technology to accelerate core technology breakthroughs, promote domestic substitution, and jointly build a solid foundation for independent and controllable industries.
