Established in 1998 with 320 staff members and a registered capital of $1.5 million, Ningbo Hui Hesing Advanced-tech Material Co. Ltd is specialized in manufacturing and selling all kinds of permanent magnetic products. Our products are exported to North and South America, Western Europe, Australia, and Africa, and we have an annual sales volume exceeding $9.6 million. Our target customers are import traders and wholesalers. Some big names have been cooperating with us for over eight years. Our two major advantages over our competitors are that we own raw material factories, and we are located very close to the port for ease of transportation and trading. As such, our prices are competitively priced compared to those of other suppliers. We're also an ISO 9001:2000-certified manufacturer and able to produce up to 1,000 tons of DfES magnets, 8,000 tons of ferrite magnets and over 10 million magnetic assemblies annually.
