About Chongqing Seatrend Technology & Development Co. Ltd. - Magnets & Magnetic Products Supplier in China

China, operating a catalogue of 10 active products, Chongqing Seatrend Technology & Development Co. Ltd. lists items under Magnets & Magnetic Products, Industrial Supplies and Electric Sockets & Plugs. The catalogue includes a high‑quality sintered hard ferrite magnet, several decorative fridge magnets, and an EU‑standard smart socket. Products such as the Cute Toy High Technology Magnetic Floating Ball are classified under HS code 9503.00 and combine a neodymium NdFeB core with an ABS plastic shell and electronic control unit. Additional fridge‑magnet variants use EVA foam or PVC vinyl with ferrite or strontium‑ferrite backing and fall under HS codes 8505.19. The supplier’s product set therefore spans magnetic materials, plastic‑encapsulated toys, and electrical accessories.

Product Range and Specialties of Chongqing Seatrend Technology & Development Co. Ltd.

Chongqing Seatrend’s catalogue covers three sub‑categories. In the magnet segment, products range from bulk sintered hard ferrite blocks to small decorative fridge magnets with ferrite or neodymium cores. Industry standards for ferrite magnets specify a density of 4.8 - 5.0 g/cm³ and a coercivity of 80 - 120 kA/m, while neodymium NdFeB magnets used in the floating ball typically meet N35‑N42 grades and require a protective coating. The smart socket is designed for EU markets and follows IEC 60884‑1 specifications for voltage rating (250 V AC) and current (10 A), with CE marking as a common compliance requirement. EVA foam magnets are produced with a foam density of 0.03 - 0.07 g/cm³ and are often supplied in packs of 50 - 100 pieces per 20‑ft container.

Trade and Export Information - Chongqing Seatrend Technology & Development Co. Ltd.

China is a leading exporter of magnetic components and plastic‑encapsulated toys, with the majority of shipments destined for Europe, North America and Southeast Asia. HS code 8505.19 for ferrite magnets and 9503.00 for magnetic toys are subject to customs inspections that verify magnetic content, material safety data sheets and, where applicable, CE or FCC compliance. Buyers typically request certificates such as ISO 9001 for quality management, CE for electrical accessories, and RoHS declarations for products containing neodymium. Packaging for magnets often uses anti‑static bags or wooden crates to prevent breakage, while plastic toys are shipped in sealed cartons of 500 units per 20‑ft container. Common Incoterms for these exports are FOB Chongqing or CIF European ports, with freight forwarders handling bulk handling due to the weight of magnetic material.

Sourcing from Chongqing Seatrend Technology & Development Co. Ltd. - Buyer Guidance

Purchasers should obtain a material safety data sheet and a magnetic performance test report that lists residual flux density (Br), coercivity (Hc) and temperature stability for each magnet type. For the smart socket, request a CE test certificate, an IEC 60884‑1 conformity report and a RoHS declaration to confirm compliance with European regulations. Sample orders of 100 - 200 fridge magnets are standard for evaluating print quality and magnetic strength before scaling to container loads. Verify the HS code on the commercial invoice matches the product description to avoid customs delays. Confirm packaging details, such as anti‑static lining for ferrite magnets or sealed plastic wrap for EVA toys, to ensure product integrity during sea transit.

What HS codes are used for the magnetic products?

The sintered hard ferrite magnet falls under HS chapter 85, typically coded 8505.19; decorative and EVA fridge magnets also use 8505.19, while the magnetic floating ball toy is classified under HS code 9503.00.

Which certifications are commonly required for the EU‑standard smart socket?

Buyers usually request CE marking, an IEC 60884‑1 conformity test report, and a RoHS declaration to demonstrate compliance with European electrical safety and hazardous substance limits.

What magnetic performance specifications should I check for the ferrite magnets?

Key parameters include residual flux density (Br) around 0.3 - 0.5 Tesla, coercivity (Hc) of 80 - 120 kA/m, and a density of approximately 4.9 g/cm³; test reports should provide these values at 20 °C.

How are the EVA foam fridge magnets typically packaged for export?

They are commonly packed in sealed cardboard cartons, with 500 - 1,000 units per carton and anti‑static lining for the magnetic layer, then stacked on pallets for 20‑ft container loading.

What sample quantity is practical for evaluating the decorative fridge magnets?

A sample batch of 100 - 200 pieces, representing the full design range, allows inspection of print accuracy, magnetic strength, and durability before placing larger orders.

Which markets import Chinese magnetic components most frequently?

Europe, the United States and Southeast Asian countries such as Vietnam and Thailand are the primary destinations for Chinese ferrite and neodymium magnetic products.

What documentation is needed to clear customs for products with HS code 9503.00?

Exporters should provide a commercial invoice, packing list, material safety data sheet, and, when required, a test report confirming the toy complies with the relevant safety standard (e.g., EN 71).
