Wholesale whiteboard magnets

Buyers should distinguish between Neodymium (NdFeB) magnets, which offer high strength in small sizes, and Ferrite (Ceramic) magnets, which are more cost-effective for bulk utility. Ensure the magnetic grade (e.g., N35, N52) is clearly specified, as this determines the holding power. For plastic-encased magnets, prioritize ABS plastic shells over cheaper recycled plastics to ensure impact resistance and color vibrancy.

Compliance is critical, especially for educational or office supplies. Ensure products meet EN71 (Part 1-3) for the EU market and ASTM F963 for the US, specifically regarding small parts and magnet ingestion hazards. For industrial or office use, verify RoHS and REACH compliance to ensure the absence of hazardous substances like lead or cadmium in the coatings and plastic components.

A premium magnet must have a scratch-resistant base, often achieved through a smooth epoxy coating or a felt/rubber padding to protect the whiteboard surface. The ergonomic design (such as a push-pin or pawn shape) is essential for ease of handling in fast-paced office environments. Additionally, check the pull force rating; a standard office magnet should reliably hold at least 5-10 sheets of A4 paper without sliding.

Most professional suppliers on Made-in-China.com offer OEM/ODM services. This includes custom logo printing (silk screen or pad printing), bespoke color matching via Pantone codes, and specialized packaging such as blister packs or tin boxes for retail readiness. For high-volume orders, you can also request custom magnetic flux density to meet specific industrial requirements.

Magnets are classified as 'Dangerous Goods' for air freight if their magnetic field strength exceeds specific limits (0.00525 gauss at 15 feet). You must ensure the supplier provides Magnetic Shielding Packaging and a Non-Magnetic Inspection Report from recognized bodies like DGM. For large wholesale quantities, sea freight is the most economical and less regulated method, though proper moisture-proof packaging is still required to prevent oxidation of the magnet cores.

Always request a pre-production sample and a Third-Party Inspection (TPI) before final payment. Use the Secured Trading services on Made-in-China.com to protect your funds until the goods are verified. Specifically, ask for a salt spray test report for the nickel or zinc plating to ensure the magnets won't rust in humid climates, which is a common failure point in low-quality batches.

Magnet prices are highly sensitive to the market price of Rare Earth elements (like Neodymium and Dysprosium). Negotiate based on a tiered pricing model linked to raw material indices. To secure better rates, offer a forecasted annual volume rather than a one-off spot buy, and consider standardizing sizes to utilize the supplier's existing molds, which eliminates tooling costs.

Verify the supplier's Audit Reports and Business Licenses directly on their Made-in-China.com profile. Ensure the Incoterms (e.g., FOB, CIF, or DDP) are clearly defined in the Proforma Invoice. Avoid using untraceable payment methods; instead, utilize Letter of Credit (L/C) for very large volumes or Telegraphic Transfer (T/T) with a clear milestone-based payment schedule (e.g., 30% deposit, 70% against B/L copy).
