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

Sinomake Industry Co., Ltd is based in China and currently lists five active magnet products. The catalogue covers neodymium iron boron (NdFeB) magnets designated NDFEB, ferrite magnets, alnico magnets, samarium cobalt (SmCo) magnets, and rubber magnets. All five items fall under HS chapter 85, specifically HS code 8505.11 for permanent magnets. The NdFeB entry specifies alloy grades N45 to N52, while the ferrite entry notes sintered ceramic composition of iron oxide with barium or strontium carbonate. The alnico and SmCo entries describe their respective alloy systems, and the rubber magnet entry is listed without a material description.

In addition to the magnet line, the supplier includes a secondary category for labels, stickers and logos, indicating capability to produce printed adhesive products, although detailed specifications are not enumerated in the catalogue. The combination of magnetic components and printed labeling solutions suggests a focus on components for assembly and identification in industrial applications. The product set is positioned for export from China, where the majority of rare‑earth and specialty magnet production is concentrated. The supplier’s trust tier is listed as “harbor,” reflecting a moderate level of verification in trade platforms. Buyers can reference the HS code 8505.11 when arranging customs documentation for the magnet items.

Product Range and Specialties of Sinomake Industry Co., Ltd

The catalogue lists four alloy‑based permanent magnets with explicit material descriptions: NdFeB magnets in grades N45‑N52, sintered ferrite ceramics, AlNiCo alloy magnets, and SmCo magnets (SmCo5 or Sm2Co17). In the magnet industry, NdFeB grades N45‑N52 correspond to residual flux densities of roughly 1.2‑1.4 Tesla and coercive forces above 800 kA/m, suitable for high‑performance electronics and automotive motors. Ferrite magnets are typically ceramic grade with a maximum energy product around 0.35 Tesla and are valued for corrosion resistance and cost efficiency. AlNiCo magnets offer high temperature stability up to 550 °C but lower energy product (~0.15 Tesla), while SmCo magnets provide high temperature tolerance (up to 350 °C) and excellent corrosion resistance with energy products near 0.5 Tesla. The rubber magnet, though not detailed, is usually a flexible composite of ferrite powder bound in a rubber matrix, used for sealing and low‑strength applications. The supplier’s secondary label and sticker category generally involves printed adhesive media such as paper, vinyl or polymer films, offered in standard dimensions (e.g., A4, roll widths of 300 mm) and common finishes like matte or gloss, which are typical for industrial branding and safety markings.

Trade and Export Information - Sinomake Industry Co., Ltd

China accounts for over 80 % of global rare‑earth magnet output, and exporters of HS 8505.11 products commonly ship to regions including North America, Europe, Southeast Asia and the Middle East for use in electric vehicles, renewable‑energy turbines, consumer electronics and automation equipment. Buyers typically require compliance with IEC 60404‑5 for magnetic safety, as well as RoHS and REACH declarations for hazardous substances. Standard export packaging for NdFeB and SmCo magnets includes anti‑corrosion coating, individual poly‑bagging and bulk packing in wooden crates or 20‑ft containers, with a typical load of 2 000 - 3 000 kg per container depending on magnet size. Importing countries often request test reports showing BH curves, residual flux density (Br), intrinsic coercivity (Hci) and temperature coefficients, and may ask for ISO 9001 or ISO 14001 certification from the supplier. For ferrite and AlNiCo magnets, IEC 60404‑1 and ASTM B221 are common reference standards, and bulk shipments may be palletized on Euro‑pallets with shrink‑wrap. The label and sticker segment follows graphic‑industry standards such as ISO 12647 for colour management and may need FDA or EU‑specific approvals when used on food‑contact packaging.

Sourcing from Sinomake Industry Co., Ltd - Buyer Guidance

When sourcing magnets from Sinomake Industry Co., Ltd, buyers should request material certificates confirming the exact alloy composition and grade (e.g., NdFeB N48, SmCo5). Test reports should include magnetic performance data such as residual flux density (Br) in Tesla, coercive force (Hci) in kA/m, and temperature‑stability curves. For the rubber magnet, a formulation sheet detailing ferrite loading and rubber type helps assess suitability for sealing or vibration‑damping uses. Buyers are advised to verify that the supplier can provide RoHS, REACH and IEC safety documentation, and to ask whether ISO 9001 quality‑management certification is in place. Confirm packaging details - individual anti‑corrosion coating, poly‑bagging and crate dimensions - to ensure safe transport, and clarify the minimum order quantity, which for specialty alloys often starts at 500 pieces per grade. Requesting a pre‑production sample with a full test report is a standard practice to validate magnetic properties before committing to larger volumes.

What magnet types does Sinomake Industry Co., Ltd list in its catalogue?

The catalogue includes neodymium iron boron (NdFeB) magnets, sintered ferrite magnets, aluminum‑nickel‑cobalt (AlNiCo) magnets, samarium cobalt (SmCo) magnets and rubber magnets, all classified under HS code 8505.11.

Which HS code applies to the magnets offered by this supplier?

All five magnet products are assigned HS code 8505.11, the standard code for permanent magnets of iron alloys, rare‑earth alloys or ferrites.

What material grades are specified for the NdFeB magnets?

The NdFeB entry mentions alloy grades ranging from N45 to N52, which correspond to residual flux densities between approximately 1.2 Tesla and 1.4 Tesla.

Are certifications such as ISO 9001 or RoHS confirmed for this supplier?

The supplier’s facts do not list any certifications; buyers should request copies of ISO 9001, RoHS or REACH compliance certificates before placing an order.

What typical specifications should a buyer verify for SmCo magnets?

Buyers should verify the alloy type (SmCo5 or Sm2Co17), the intrinsic coercivity (Hci) above 1 MA, and the maximum operating temperature, which can reach 350 °C for SmCo alloys.

What documentation is generally required for importing these magnets?

Importers normally ask for a material certificate, magnetic performance test report (including Br and Hci), RoHS/REACH declarations and a commercial invoice referencing HS 8505.11.

How are the magnets typically packaged for export?

Standard export packaging includes anti‑corrosion coating, individual poly‑bagging and bulk packing in wooden crates or 20‑ft containers, with pallets shrink‑wrapped to protect against mechanical damage.
