About Ningbo Maxim Magnetic Industry Co., Ltd. - Magnets & Magnetic Products Supplier in China

China‑based Ningbo Maxim Magnetic Industry Co., Ltd. lists fifteen distinct magnetic products across the categories “Magnets & Magnetic Products” and “Machined Components.” The catalogue spans permanent disc magnets, arc‑shaped motor magnets, block magnets, name‑badge magnets, and custom Halbach arrays, all classified under HS 8505.11 or HS 8505.19, with one badge type under HS 8306.30. Materials are specified as sintered Neodymium‑Iron‑Boron (NdFeB) alloys, with grades ranging from N35 to N52, and some items incorporate steel or ABS housings for durability.

The product list includes a Super Strong Rare Earth Permanent Magnet Disc (HS 8505.11, NdFeB sintered), Arc Shaped Magnets for Electric Motors (HS 8505.19, NdFeB N42/N52), and a Super Strong Neodymium Pot Magnet (HS 8505.11, NdFeB N42/N52 with steel housing). Additional items such as Magnetic Name Badges combine NdFeB discs with iron or ABS bases, while the Halbach Array variants use NdFeB grades N35‑N52. All items are described by material composition rather than coating, size, or weight, reflecting the supplier’s focus on raw magnetic performance.

Product Range and Specialties of Ningbo Maxim Magnetic Industry Co., Ltd.

The catalogue concentrates on NdFeB permanent magnets in disc, block, and custom array forms. Typical industry grades for NdFeB magnets range from N35 (≈1.2 T remanence) up to N52 (≈1.45 T), with coercivity values from 800 kA/m to 1 500 kA/m. Buyers often require compliance with IEC 60404‑2 for safety and ASTM B555 for material certification. In addition to raw NdFeB, manufacturers frequently offer nickel‑copper‑nickel plating, epoxy coating, or polymer encasement to improve corrosion resistance, especially for automotive or industrial motor applications.

Chinese magnet exporters usually ship products in 20‑ft or 40‑ft containers, using wooden crates or reinforced cardboard boxes with individual units wrapped in anti‑static film. Standard packaging dimensions for disc magnets are often 100 mm × 100 mm × 5 mm, while block magnets may be supplied in 50 mm × 50 mm × 20 mm sizes. Bulk orders of custom Halbach arrays are typically quoted per kilogram, with typical densities of 7.5 g/cm³ for NdFeB alloys.

Trade and Export Information - Ningbo Maxim Magnetic Industry Co., Ltd.

Exporters of NdFeB magnets from China commonly target automotive manufacturers in the United States, Europe, Japan, and South Korea, as well as electronics assemblers requiring high‑energy‑product components. The HS 8505.11 code covers sintered rare‑earth magnets, while HS 8505.19 applies to other permanent magnet assemblies; both codes are subject to standard customs valuation and may trigger anti‑dumping duties in certain jurisdictions.

Typical certifications requested by importers include ISO 9001 quality management, CE marking for EU market compliance, and RoHS for restriction of hazardous substances. Inspection agencies such as SGS or BV often perform magnetic property testing (remanence, coercivity, BHmax) and dimensional checks before shipment. Common Incoterms are FOB Ningbo Port or CIF destination, with freight forwarding handled through major Chinese ports and consolidated container services.

Sourcing from Ningbo Maxim Magnetic Industry Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request a detailed material test report that lists grade designation (e.g., N52), remanence (Br), coercivity (Hc), and maximum energy product (BHmax). Verify the coating type - if corrosion resistance is required, ask for certification of nickel‑copper‑nickel plating thickness or epoxy coverage. Confirm packaging specifications, such as individual magnet wrapping and container palletization, to prevent breakage during transit.

Typical due‑diligence steps include checking the supplier’s ISO 9001 certificate, requesting a third‑party inspection report for magnetic performance, and clarifying the minimum order quantity (often 500 pcs for standard discs or 50 kg for bulk blocks). Lead times for standard NdFeB discs are usually 15‑25 working days, while custom Halbach arrays may require 30‑45 days depending on design complexity.

What HS codes are used for the magnets offered by Ningbo Maxim Magnetic Industry?

The disc, block, and custom array magnets are classified under HS 8505.11, while the arc‑shaped motor magnets use HS 8505.19. The iron‑base badge magnet falls under HS 8306.30.

Which NdFeB grades are available in the product list?

Grades span from N35 up to N52, with specific items noting N42, N52, and a range N35‑N52 for custom Halbach arrays.

What material certifications should a buyer request?

Buyers should request an ISO 9001 quality management certificate, a material test report showing grade, Br, Hc and BHmax, and any relevant CE or RoHS compliance documents.

Are coating options available for the magnets?

The catalogue mentions steel or ABS housings for badge magnets, but does not specify coating. Buyers should ask the supplier to confirm if nickel‑copper‑nickel plating or epoxy coating can be applied.

What are typical packaging methods for these magnets?

Standard practice is individual anti‑static wrapping, placed in reinforced cardboard boxes, and pallets stacked in 20‑ft or 40‑ft containers for ocean freight.

What are common minimum order quantities and lead times?

Standard disc magnets often have an MOQ of 500 pieces, while bulk block magnets may start at 50 kg. Lead times range from 15 to 25 working days for standard items and 30‑45 days for custom Halbach arrays.

Which markets commonly import Chinese NdFeB magnets?

Major importers include the United States, Germany, Japan, South Korea, and the United Kingdom, primarily for automotive motors, wind‑turbine generators, and consumer electronics.

What Incoterms are typically used for shipping?

Suppliers usually quote FOB Ningbo Port or CIF to the buyer’s destination, with freight handled by major container lines.
