History and differences MAH and DMAH
In 2005 , the Japanese Ministry of Health, Labour and Welfare (MHLW) implemented the new Pharmaceutical Affairs Law (PAL) and this referred to as a Marketing Authorization Holder (MAH) system. In the past, foreign manufacturer of medical devices without a local office in Japan utilized an In-Country Caretaker (ICC) as their agent to import their medical devices to Japan.
Under the new PAL now called the PMDL (Pharmaceuticals and Medical Devices Law) all foreign manufacturer have to appoint a MAH. Usually the foreign manufacturer appointed his distributor as a MAH. This could cause some trouble in the business if the manufacturer want to change the distributor, or add other distributor, due the MAH is the license holder of the product license. The MHLW has recognized this challenge for foreign manufacturer and included in the new PMDL an opportunity to select an independent ‘designated‘ MAH (DMAH). This is called the ‘Foreign Special Approval System ‘under PMDL.
Differences between MAH and DMAH
(MAH : Marketing Authorization Holder / DMAH : Designated Marketing Authorization Holder)
The MAH controls the product license of the medical device, he is the applicant and becomes the owner of the license.
The MAH need no signature from the foreign manufacturer if a supplement application or transfer application of the product license is submitted, the MAH is the owner of the product license, so he can submit the application under their responsibility.
In a DMAH case, the foreign manufacturer is the applicant and becomes the owner of the product license. He controls the registration of the medical device.
Foreign manufacturer cannot easily obtain the license of MAH, so the manufacturer must appoint a stationed company based in Japan, who has the appropriate MAH license, and designated it as DMAH.
The DMAH act as the representative for the foreign manufacturer during and after the product registration process.
The application will be submitted from the DMAH to the authorities, but requires the signature of the foreign manufacturer.
Every change or supplement application or transfer application of the product license require the signature of the representative person of the foreign manufacturer. Submitted via the DMAH to the authorities.
Change of the DMAH is much easier compare to the case of MAH. Tasks of the MAH and DMAH are almost the same, such as responsibility for GVP and GQP.
A foreign manufacturer should determine carefully, by considering the environment, his business partner and the situation of his own company.
