Manufacturer Code

Each Member (except interested parties) will be assigned on their request a Manufacturer Code that shall be used to uniquely identify their products.   

In order to avoid Manufacturer Codes being unnecessarily assigned, (e.g. in the case of a Member that is not yet active in the market), a Member shall only apply for its Manufacturer Code shortly before it intends to actually launch products on the market.
