Factors that make Zakaat compulsory

Value of zakaatable goods

Q: I own a textile mill. I first import the yarn from which the material is manufactured. I supply certain companies material at the manufacturing cost plus ten percent profit. I also wholesale fabric at the wholesale price which is approximately my cost plus twenty percent. I am also a retailer and supply the public at the retail price. When calculating my zakaat, which market am I obligated to take into consideration? Should I evaluate my wealth in accordance to the retailer’s market, wholesaler’s market, or the manufacturer’s market?
