Ningbo Kaiton International Trade Co., Ltd. and Ningbo Kaiton Resource Co., Ltd. are state-owned integrated commodity trading service providers, mainly engaged in domestic and foreign trade of non-ferrous metals such as copper, zinc, aluminum, and nickel. As wholly-owned subsidiaries of Ningbo Development & Investment Group Co., Ltd., Kaiton plays a leading role in the commodity trading sector of the Group and has the largest business scale among all state-owned trading companies in Ningbo. The total annual revenue of the two companies has exceeded 40 billion Yuan with registered capital of 400 million Yuan.    

Relying on its significant advantages in shareholder background and abundant working capital, Kaiton has gradually formed a two-wheel-driven development model of “Industry+Finance” based on the traditional physical trading pattern. With the robust development over the past years, Kaiton has established a solid network with hundreds of large smelters, trading houses as well as manufacturing and processing companies from across the country, and has taken the lead in regional non-ferrous metals trading.  

During the 14th Five-Year Plan period (2021-25), guided by the "dual circulation" development paradigm proposed by the CPC Central Committee--with domestic circulation as the mainstay and domestic and international circulations reinforcing each other, Kaiton will continuously focus on the core varieties of non-ferrous metals. It is committed to building an integrated supply chain service system that can have access to overseas superior resources, consolidate domestic industrial chain and serve regional economic development, and is making great strides towards a 100 billion-scale supply chain conglomerate.
