A license Holder, or Authorized Marketing Holder, is a Company authorized to Import products subject to authorization/license/registration on behalf of foreign companies.
Mainly used for Healthcare products like Dietary Supplements, Cosmetics and Medical Device, License holding allow the manufacturer to keep the control of Intellectual property and of the market strategy for his product. A local distributor won;t have any right on the licenses and then can be easily changed in case of underperformance without any consequence.
