Private labeling is precisely what it sounds like; you go up to a manufacturer and ask them to give you pre-developed and pre-tested products, which you must take to market with your brand name and packaging. The manufacturer controls the development (Specification, formulation) in this process. When buyers procure a product using private label manufacturing, they are typically putting their name on a product that the manufacturer has already designed and built. In this case, the manufacturer usually has control of the development, specifications, and manufacturing.
