China-Base Ningbo Foreign Trade Co., Ltd.

China-Base Ningbo Foreign Trade Co., Ltd. is located in Ningbo, Zhejiang Province, China and lists twelve active products under the magnet and magnetic product umbrella. The catalogue includes a PMDC motor, educational magnetic toys and a magnetic flat floor sweeper, the latter recorded under HS code 8505.19 and built with permanent ferrite or NdFeB magnets combined with a steel frame. Additional entries cover stainless steel hexagon bars (HS 7222.20) and a series of permanent magnets such as arc‑bonded NdFeB, ferrite ring, sintered SmCo, sintered Alnico and various NdFeB grades, all classified under HS codes 8505.11 or 8505.19. Materials mentioned span strontium and barium ferrite ceramics, rare‑earth NdFeB alloys ranging from N35 to N52, samarium‑cobalt alloys (Sm2Co17, SmCo5) and Alnico compositions with defined percentages of aluminum, nickel, cobalt, iron, copper and titanium. The product list therefore comprises both raw magnetic material forms and finished magnetic components used in industrial and consumer applications.

The supplier’s magnetic product portfolio includes permanent magnetic chucks, magnetic frame filters, and dense magnetic rings, each described with specific material grades such as ferrite grade 8, NdFeB N52, or SmCo Sm2Co17. HS codes 8505.11 identify solid permanent magnets while 8505.19 covers magnetic articles and assemblies, reflecting standard customs classification for such goods. Typical product specifications in this segment involve magnetic flux density values between 0.3 and 1.5 Tesla, coercivity ranging from 800 kA/m for ferrite to over 1500 kA/m for high‑grade NdFeB, and operating temperature limits up to 150 °C for SmCo alloys. Packaging is commonly in wooden crates or steel pallets with anti‑corrosion coating to protect the magnets during transport.

The catalogue presents a mix of raw magnet materials and finished magnetic devices. Products such as arc‑bonded NdFeB magnets, ferrite ring magnets, sintered SmCo, sintered Alnico and NdFeB sintered blocks are listed with grades that correspond to industry standards: ferrite grade 8, NdFeB grades N35‑N52, SmCo grades Sm2Co17 and SmCo5, and Alnico compositions defined by alloy percentages. In practice, buyers of these magnets often request data sheets that include residual induction (Br) values, coercive force (Hc), maximum energy product (BHmax) and temperature coefficients. Magnetic components like the circular dense permanent magnetic chuck or magnetic frame filters typically incorporate a mild steel or stainless steel housing, and the flat floor sweeper combines a ferrite or NdFeB core with a steel frame for durability. Standard industry coatings include nickel‑copper‑nickel (Ni‑Cu‑Ni) plating, epoxy resin or rubber encapsulation to improve corrosion resistance and handling safety.

Industry practice for these categories emphasizes compliance with IEC 60404 safety standards for magnetic devices and ISO 9001 quality management for manufacturing processes. Rare‑earth magnet exporters from China frequently certify RoHS and REACH conformity to meet European Union requirements, while magnetic assemblies destined for automotive or renewable‑energy applications may also need UL or CE marking depending on the target market.
