China’s National Medical Products Administration (NMPA) Class II medical device registration represents a significant quality benchmark for therapy patches. For overseas distributors evaluating which patch products to stock, understanding the differences between far-infrared, magnetic, and traditional herbal patches is essential for making the right purchasing decision.
What NMPA Class II Means
NMPA Class II medical devices are defined as products requiring controlled management to ensure safety and effectiveness. For therapy patches, Class II registration requires:
- Clinical efficacy data — Proof that the product delivers its claimed therapeutic benefits
- Biocompatibility testing — Skin safety validation for prolonged contact
- Sterile manufacturing — Production in Class 100K (ISO Class 8) cleanroom facilities
- Quality management system — Full compliance with medical device QMS standards
- Post-market surveillance — Ongoing safety monitoring and adverse event reporting
This regulatory rigor gives overseas buyers confidence in product safety and quality that unregistered patches cannot match.
Far-Infrared Therapy Patches
Registration: 鄂械注准 20252095452 (valid 2025-03-17 to 2030-03-16)
How It Works
Far-infrared ceramic powder embedded in the patch matrix emits therapeutic wavelengths (4-16 μm) that penetrate the skin to a depth of 3-5cm. This gentle thermal effect promotes local blood circulation, reduces inflammation, and provides pain relief without external heat sources.
Best For
- Chronic pain management — Cervical, lumbar, and joint pain
- Post-injury recovery — Muscle strains and soft tissue injuries
- Elderly care — Non-invasive pain relief for sensitive populations
- Physical therapy clinics — Professional treatment complement
Available Models
5 specialized shapes for different body parts: neck, shoulder, lumbar, leg, and joint patches.
Magnetic Therapy Patches
Registration: 鄂械注准 20242095328 (valid 2024-12-26 to 2029-12-25)
How It Works
Integrated magnetic pieces create a static magnetic field (typically 100-200mT) that interacts with iron-rich blood components. This magnetic stimulation is believed to enhance local circulation, accelerate tissue repair, and provide analgesic effects.
Best For
- Sports medicine — Athletic injury recovery and performance support
- Acute pain relief — Sprains, strains, and impact injuries
- Wellness retail — Consumer-friendly format with “magnetic therapy” appeal
- Tissue healing support — Post-surgical recovery (with physician guidance)
Available Models
4 specialized shapes: neck, shoulder, lumbar, and leg patches.
Traditional Herbal Patches
How It Works
Formulated with traditional Chinese medicine herbal extracts, these patches deliver active compounds through transdermal absorption. Common ingredients include mugwort, angelica, safflower, and other warming herbs that promote circulation and relieve discomfort.
Best For
- TCM market segment — Customers familiar with traditional Chinese medicine
- Sanfu patch treatments — Seasonal wellness therapy (summer application)
- Wellness centers — Holistic health and alternative therapy markets
- Cultural communities — Asian diaspora markets with TCM familiarity

Selection Strategy by Market Segment
For Pharmacy Chains
Stock far-infrared patches as the primary product — the clinical evidence and NMPA registration provide strong selling points. Add magnetic patches as a premium option for sports-minded customers.
For Wellness Centers
A combination of magnetic and traditional herbal patches offers the broadest appeal. Magnetic patches attract wellness enthusiasts, while herbal patches serve customers seeking traditional medicine solutions.
For Physical Therapy Clinics
Far-infrared patches are the clinical workhorse. Their non-invasive nature and proven efficacy make them ideal for professional treatment protocols.
For E-commerce / DTC Brands
Lead with magnetic therapy patches — the “magnetic therapy” concept has strong consumer marketing appeal. Bundle with far-infrared patches for a complete product line.
