I want to know details about the percentage taken by different players in the supply chain
Every player in supply chain takes a commission out of goods passing through him/her. This is how the channel remains self-sustaining. The extent of commission depends upon many factors such as how many players, kind of goods (e.g. perishable that require special storage), which market etc. However, there is an industry consensus on range of commission for players in a distribution channel including distributors (pl note, there may be more players than distributors in a supply channel)
Please read following article describing range of commission for various players. Please consult an experienced distribution trade professional for advice
Hope the above helps. Please feel free to contact us and follow us for more information on distribution trade.
