Medical Device Classification Consulting and Japan JMDN Code Research

ANSWERED ON THIS PAGE:

  • How are medical devices classified in Japan?
  • How are IVDs classified?
  • What are JMDN codes?

Before you can legally sell your product in Japan, you must comply with the regulatory requirements of the Pharmaceutical and Medical Device Agency (PMDA), within the Japanese Ministry of Health, Labour and Welfare (MHLW). Classification dictates the regulatory procedure for your device, so it is vitally important to determine the correct medical device classification and product code for your product before beginning the registration process.

How medical devices are classified in Japan

Medical devices in Japan are classified based on risk to the human body. The PMDA uses a tiered classification system for medical devices as shown below. Have an IVD? See this page.

  • General – CLASS I (low risk)
  • Specified Controlled – CLASS II (low/medium risk)
  • Controlled – CLASS II (medium risk)
  • Highly Controlled – CLASS III (medium/high risk)
  • Highly Controlled – CLASS IV (high risk)

Your device's risk level determines your approval route. Pre-market Certification (PMC, or Ninsho) is for Specified Controlled – Class II devices. Pre-market Approval (PMA, or Shonin) is required for Controlled – Class II, Highly Controlled – Class III, and Highly Controlled – Class IV devices.

Japan Medical Device Nomenclature (JMDN codes)

The MHLW maintains a database of generic medical device descriptions with associated Japan Medical Device Nomenclature (JMDN) codes. This system is similar to the US FDA system of product codes or Global Medical Device Nomenclature (GMDN) system. Familiarity with the JMDN database and fluency in Japanese are essential to determine your device's code.

If your device's code does not exist, products must go through a new device pathway, and classification is determined by risk according to the classification rules in Yakusyokuhatsu No. 0720022. However, final determination of your device classification would be made by the MHLW.
