Offtake refers to the process by which a buyer or user agrees to purchase or take delivery of a commodity, product or service from a producer, supplier or seller. In other words, it is an agreement between two parties where one party (the off taker) commits to purchasing all or part of the output produced by another party (the producer). This term is commonly used in industries such as agriculture, mining and energy production, where there are often long-term contracts for the sale of raw materials or finished products.
