Magnetic therapy

Buyers must focus on Magnetic Flux Density (measured in Gauss or Tesla) to ensure therapeutic efficacy. For static magnets, a surface strength of 1,000 to 4,000 Gauss is standard for consumer goods. Additionally, verify the polarity alignment (unipolar vs. bipolar) and the material composition, such as Neodymium (NdFeB) for high strength or Ferrite for cost-effectiveness. Ensure the housing material is biocompatible (e.g., medical-grade silicone or 316L stainless steel) to prevent skin irritation.

Since these are often classified as medical devices or wellness products, they must meet ISO 13485 (Medical Devices Quality Management Systems). For the US market, FDA Registration is crucial, while the EU market requires CE Marking (MDR 2017/745). Furthermore, ensure products comply with RoHS and REACH to guarantee they are free from hazardous substances like lead or cadmium.

Request third-party lab reports that confirm the magnetic field stability after repeated use. For wearable items like braces or jewelry, perform salt spray tests to check for corrosion resistance and tensile strength tests for fabric durability. It is essential to verify that the magnets are securely encapsulated to prevent them from becoming choking hazards or losing their position during washing cycles.

Magnetic therapy products are widely used in physiotherapy clinics, sports recovery centers, and home wellness. Functional requirements include ergonomic design for targeted pain relief (e.g., lumbar belts or knee sleeves) and breathability of the carrier material. For electronic Pulsed Electromagnetic Field (PEMF) devices, ensure adjustable frequency settings and overheat protection are integrated into the circuitry.

Magnets are classified as 'Dangerous Goods' for air freight because they can interfere with aircraft navigation systems. You must ensure the supplier provides a Magnetic Inspection Report and uses shielded packaging (iron sheets or specialized foam) to neutralize the external magnetic field. Failure to do so can lead to shipment rejection or heavy fines at customs.

Always utilize the Secured Trading Service on Made-in-China.com to protect your payments. When negotiating, request a detailed Proforma Invoice (PI) that specifies the Gauss rating, material grade, and certification numbers. For bulk orders, negotiate a 30% deposit and 70% balance payment only after a successful pre-shipment inspection (PSI) by a third-party agency like SGS or Intertek.

Before importing, conduct a patent search in your target market to ensure the magnetic design or PEMF technology does not infringe on existing patents. When sourcing from Made-in-China.com, prioritize Audited Suppliers who hold their own R&D patents and can provide OEM/ODM authorization letters to prove their right to manufacture and export the specific design.

Be aware of Anti-Dumping Duties (ADD) or specific tariffs on rare-earth magnets (like Neodymium) which fluctuate based on trade relations. Check the HS Code (typically 8505.11 or 9019.10) against your country's tariff schedule. To optimize costs, consider DDP (Delivered Duty Paid) terms if the supplier has a robust logistics network in your region, as this simplifies the tax and customs clearance process.
