The price of a organic substance such as Royal Jelly depends on several factors. First of all, the quality of Royal Jelly is the most important factor in determining its price. The higher quality equals the higher price.
Second factor is which country has produced this product and what is the production capacity of that country. For example, the price of China Royal Jelly is much cheaper than Iran.
The price of Royal Jelly in world markets is variable and last year was the highest price of this product.
So the price depends on these things, but if you want to sell Royal Jelly in the global market, the quality of your product must be within the standard to get a good price and be welcomed.
