MAH・DMAH

In Japan, a Marketing Authorization Holder (MAH) is required to place medical devices on the market and is legally responsible for regulatory submissions as well as post-market quality and safety management.

As a licensed medical device MAH, Micron provides comprehensive, end-to-end support covering the entire lifecycle of medical devices—from regulatory submissions to post-market quality and safety management.
We support both Marketing Authorization Holders (MAH) and Designated Marketing Authorization Holders (DMAH).

Marketing Authorization Holder (MAH)

A Marketing Authorization Holder (MAH) is the legal entity responsible for placing medical devices on the Japanese market.
The MAH assumes full legal responsibility for the product, including regulatory approval, post-market safety management, and quality management.

Designated Marketing Authorization Holder (DMAH)

A Designated Marketing Authorization Holder (DMAH) structure is used when an overseas company acts as the business owner.
In this arrangement, a designated MAH in Japan assumes the legal responsibility for regulatory approval and post-market activities on behalf of the overseas client.
