What is an offtake agreement?
A long-term contract under which a buyer commits to purchase an agreed share of a project’s future production. For a mine, an offtake is often what makes financing possible, because it converts uncertain future output into contracted revenue.
Key points
- Converts uncertain future output into contracted revenue.
- Often precedes the financing decision rather than following it.
- Take-or-pay and best-efforts are very different instruments.

What it commits both sides to
An offtake agreement is a long-term contract under which a buyer undertakes to purchase an agreed proportion of a project’s future output, and the producer undertakes to supply it. Terms of five to ten years are common, sometimes running to the life of the mine.
It is a commercial contract, but its real function is often financial: it converts uncertain future production into contracted revenue a lender can underwrite.
Why financing depends on it
Project lenders are not equity investors and do not want commodity price exposure or marketing risk. An offtake with a creditworthy buyer removes the question of whether the product can be sold and narrows the question to whether it can be produced.
For that reason a signed offtake frequently precedes a financing decision. It is also why a developer’s choice of offtaker matters beyond price — an offtake with a counterparty a bank will not accept has little financing value.
How the pricing usually works
Most offtakes are index-linked rather than fixed: a published reference price for the commodity, plus or minus a negotiated adjustment for grade, location and terms. Fixed-price offtakes are rare because neither side wants a decade of price risk.
The terms that decide whether an offtake is good or bad are the volume flexibility, the quality specification and penalties, the pricing period, and what happens if the mine underproduces. A take-or-pay obligation and a best-efforts obligation are very different instruments.
Frequently asked questions
- Why do mines need offtake agreements?
- Because lenders will not usually finance a project with unsold future production. An offtake converts uncertain output into contracted revenue that can be underwritten.
- Are offtake agreements fixed price?
- Rarely. Most are linked to a published index with adjustments for grade, location and delivery terms, because neither party wants to carry a decade of price risk.
- What is the difference between an offtake and a prepayment?
- An offtake is a commitment to buy future production. A prepayment is capital advanced against that commitment and repaid in product. A prepayment normally sits on top of an offtake rather than replacing it.
