On the basis of what parameters will the manufacturer release the production batch? Who will be responsible for marketing the product?
Very often too, the manufacturer and the brand must clearly establish their respective responsibilities. A manufacturer's role is to produce your product in accordance with good manufacturing practice. It does not replace your responsibility for marketing the brand. Just because a product is of high quality does not mean that it complies with the legislation of the country in which it is marketed.
As regards the parameters for releasing the batch, it is up to the brand to establish these with the manufacturer. Here again, the manufacturer cannot know your quality or regulatory requirements for you.
What services are provided by the manufacturer?
Is the cost of analyses included, as well as that of the regulatory files?
The cost price is another point that needs to be clarified. What does it include?
Are development costs included? For example, does it include the cost of storing pallets between production runs? Is the cost of analyses or regulatory files taken into account? These questions need to be raised.
