An offtake agreement is a purchase contract in which a buyer commits to take a producer's output, usually lot by lot, under terms fixed in advance. In Bolivia, where mineral supply comes from a mix of private producers, cooperatives and state companies, the offtake agreement is often the most practical way for an international buyer to secure physical material. This article explains how that works in practice: who you are actually contracting with, what has to be defined before signing, and what remains uncertain.
It is written for buyers and investors who are new to the country. We are INBEIN LTDA, a private advisory firm based in Tarija. We do not sell minerals and we do not promise outcomes. We describe how the process is built so you can judge it yourself.
What an offtake agreement means in the Bolivian context
In general terms, an offtake agreement separates two questions that are often confused: who produces the material and who buys it. The producer gets a committed buyer. The buyer gets access to supply without owning the mine. The contract describes the product, the way it is measured, the delivery point and the payment mechanism.
Bolivia has a wide mineral base: gold, silver, tin, zinc, lead, copper, tungsten, antimony, bismuth, lithium, borates (ulexite), iron, manganese and gemstones such as bolivianita. Each of these has a different producer landscape. A tin offtake and a lithium arrangement are not the same kind of conversation, and they do not involve the same counterparties. That is why a single template contract rarely fits.
Who sits on the other side of the table
The counterparty depends on the mineral and on the deposit. In practice, direct access to output means one of three groups:
- Private producers that operate their own concessions and sell their concentrate or metal.
- Cooperatives, which are an important part of Bolivian mining and often hold the actual production.
- State companies of the sector, which matter most where the State controls a resource or wants to be a party to the arrangement.
Knowing which of these you are dealing with changes everything: who signs, which permits apply, how fast decisions are made and what documents the counterparty can realistically provide. Lithium is a clear example of why this matters. Bolivia holds 9 Mt of lithium according to the USGS, the second-largest known concentration in the world. Yet the lithium contracts signed by the state company YLB with CBC (China) and Uranium One (Russia) in late 2024 remain unratified by the Legislative Assembly as of 2026. A buyer who ignores that kind of institutional detail may build a plan on a foundation that is not yet in place.
Building an offtake agreement by lot
The structure we work with is a direct purchase contract by lot. A lot is a defined quantity of a defined product, delivered and settled as a unit. Working by lot has a practical advantage: both sides can test the relationship on a limited scale before committing to a longer program.
A contract of this kind normally needs to settle the following points:
- Product definition: which mineral, in what form (ore, concentrate, metal), and with which quality parameters.
- Sampling and assays: how the material is sampled and which laboratory results both parties accept.
- Delivery point and logistics: where title and risk pass from seller to buyer.
- Payment terms: currency, timing and conditions tied to the assay results.
- Documentation: the permits and certificates the producer must supply with each lot.
- Dispute handling: what happens when assays differ or a shipment is delayed.
We do not publish volumes, prices or ticket sizes. They are quoted per lot, after the opportunity has been mapped, because they depend on the mineral, the producer and the moment.
Shared assays: how both sides trust the numbers
The most common source of friction in mineral purchases is the quality of the material. A buyer wants to know what is in the lot; a producer wants to be paid for what is really there. The answer is to share laboratory assays, so that both parties work from the same data and not from each other's claims.
In our process, assays are shared between buyer and seller. If results diverge, the contract should say in advance how the difference is resolved, for example through a third laboratory. We would rather see that clause written down before the first shipment than negotiated after a disagreement.
Logistics and shipment through Panama
Bolivia is landlocked, so every export has a transit leg. Our logistics route for shipments runs through a port in Panama. For a buyer, this means the delivery terms in the offtake agreement should state clearly where responsibility changes hands, and what documents accompany the cargo along that route.
We do not claim that logistics are simple. Timelines depend on the mineral, the origin within Bolivia and the paperwork on both sides. What we can do is map these steps before you sign, so that the contract reflects the real route and not an assumption.
Permits, timelines and risks to map first
Before any contract, we prepare what we call an opportunity map: sector, players, permits, timelines and risks. This is where an offtake agreement is either made workable or stopped early. Questions that belong in the map include:
Does the producer hold the rights and permits to extract and sell this mineral? Is the counterparty a company, a cooperative or a state entity, and who has authority to sign? Which institutions decide on the transaction, and are any decisions still pending, as with the unratified lithium contracts? Where timing or conditions are not decided, we say so plainly instead of filling the gap with a guess.
This is also where our role is useful. We open the table with the level of government that decides, whether ministries, state companies or governorates, prepare the file and accompany meetings. We hold a direct relationship at the highest level of the Government of Bolivia. We are private advisors, and that relationship is a way to reach the right decision-maker, not a substitute for the due diligence you should do.
From an offtake agreement to other structures
A direct purchase is only one route. Investors who prefer exposure to the operation rather than a single contract can consider a stockpiling fund or a stake in the operation. With the State, tokenized instruments backed by physical metal or future production are also possible, with audited reserves and a regulated listing. Bolivia's regulatory framework for this is recent: BCB Resolution 082/2024 lifted the ban on virtual assets, D.S. 5384/2025 created fintech companies licensed by ASFI, and ASFI Resolution 540/2025 created the registry of virtual assets. You can read more on our minerals page and on the opportunities section of the site.
The process itself is the same whichever route you choose: interest, opportunity map, NDA and data room when applicable, due diligence in which we answer in writing without invented figures, then vehicle and closing with KYC, using stablecoins (USDT or USDC) or fiat depending on the vehicle. Sanctioned jurisdictions are excluded. Reporting continues periodically in public.

FAQ
What is an offtake agreement for Bolivian minerals?
It is a purchase contract in which a buyer commits to take material from a producer, cooperative or state company, usually by lot. Quality, delivery and payment terms are fixed in advance.
Who are the sellers in a Bolivian offtake agreement?
They can be private producers, cooperatives or state companies of the sector. Which one applies depends on the mineral and the deposit, and it determines who signs and which permits are needed.
How are quality and shipment handled?
Laboratory assays are shared between buyer and seller, and the contract should define how differences are resolved. Shipment is organized through a port in Panama, with delivery terms stated in the contract.
Do you publish prices or volumes?
No. Volumes, prices and tickets are quoted per lot after the opportunity has been mapped, because they differ by mineral, producer and timing.
