Hello everyone, I’m an employee at Hanyao, mainly responsible for international business development. Having been deeply involved in the medical device manufacturing industry for many years, we deeply understand the pressures and concerns that buyers face when selecting a good and reliable OEM partners. This isn’t simply a purchase; it’s a process where buyers place their trust in us.
Thus, through this article, I’d like to share some of the fundamental reasons we firmly believe global buyers ultimately choose Hanyao as their supplier of medical heat patches — lies in our deep understanding of this industry and partnerships.
1. Our First Principle: Not Just “Meeting Standards,” But “Exceeding Them”
I know every OEM supplier will say they have the ISO certification. But at Hanyao, our team adheres to one principle: our standards must exceed even the minimum regulatory requirements.

- Our Understanding of “Medical”: We believe that since a medical heat patch is used, it must have the clinical-grade stability. We invest significant resources to ensure our product’s performance remains consistent across batches. Using medical-grade adhesive and skin-friendly, soft non-woven fabric is key to ensuring patient safety and efficacy.

- Our attitude to regulations: We don’t want our customers to feel anxious when entering a new market. Therefore, we’ve established a strong regulatory documentation system to ensure that when you need MDD or MDR compliance documentation, we can provide it immediately and completely. Our goal is to allow you to focus 100% on marketing, while leaving the manufacturing and compliance risks entirely to us.
2. Our Relationship: From Supplier to Co-Developer
In our view, OEM collaboration shouldn’t be a one-on-one relationship, but rather a co-development partnership.
- Listen and To do: We understand your brand’s need for uniqueness. If your goal is to develop a heating patch for sensitive skin with a 12-hour or longer heating duration, our engineers won’t say, “We only have an 8-hour version.” We’ll sit down together, adjust the formula, and try new medical adhesives until we achieve your goal together.

- Addressing the concerns about supply chain security and stability: Supply chain disruptions are a nightmare for many customers. We understand this deeply. Therefore, we’ve established a flexible production scheduling system and maintain strategic reserves of critical raw materials. This means that even with unexpected large orders, you’ll never hear us say, “We can’t do it.”

3. The Final Guarantee: Our Commitment to Product Responsibility
When you choose HanYao, you’re getting more than just a batch of heating patches; you’re also getting a team dedicated to quality.
We believe quality is the best marketing. Here I invite you to meet us at the MEDICA Trade Fair in Düsseldorf, Germany next month(Nov. 17-20). Let’s discuss how HanYao, through our commitment to medical-grade standards, can become the strongest and most reliable support for your brand.
We look forward to establishing a long-term partnership with you!
