September 18 Robusta Market Snapshot: Why a Futures Quote Is Not a Fine Robusta Offer

September 19, 2026. Historical market analysis, not a live quote or Origin Coffee Cambodia (OCC.) price.

Two price references can appear in the same coffee conversation without describing the same product. A September 18 StoneX report discussed a relatively quiet Robusta session and reported a level of 3,391. Separately, an auction scheduled for September 23–24 lists a Vietnamese anaerobic-natural Robusta with a US$5.75-per-pound opening bid. Neither number establishes what a buyer should pay for a Cambodian Fine Robusta lot; the auction has not concluded as of publication.

A price without time, instrument, quality, quantity and delivery terms is not yet a purchasing comparison. That is the essential lesson for importers and roasters evaluating an unfamiliar coffee origin.

Read the market reference precisely

StoneX's dated report described limited volatility and cited 3,391 in its Robusta discussion. It is useful as a professional historical reference, not as today's streaming quote. Separate historical price pages show different values depending on delivery month, data series or timing. Do not assume every visible number is the same settlement.

Before repeating a futures figure, record the exchange, product, delivery month, trading date, timestamp and whether it represents a settlement or a last trade. If a publication omits a field, acknowledge the gap rather than presenting the figure as a universal price. Consult the exchange's contract specifications for standardized units and expiry.

An auction is another kind of price event

Grounds for Health lists a Great Cherry Vietnamese Robusta with a US$5.75-per-pound starting bid, a stated 86 cupping score and a 132.28-pound bag in New Jersey. The catalog describes ex-warehouse pricing; shipping is excluded. Bidding is scheduled to begin September 23 and end September 24. On September 19, the opening number is not evidence of a completed sale.

A charity auction with one identifiable bag differs from commodity futures. Its eventual bid can reflect taste, rarity, the charitable purpose and specific buyer requirements. A completed result would apply to that transaction, not every Robusta or every Cambodian producer.

Quantity changes the comparison

Futures contracts are standardized products with exchange-defined specifications. A charity-auction bag is a small physical lot in a named warehouse. A Cambodian producer may have a different quantity, packaging or shipment readiness. Even a correct pounds-to-tonnes conversion can mislead when one reference excludes transport and the other reflects a distinct contract structure.

Normalize the comparison first: date, currency, quantity, delivery location, quality and transaction type. If you cannot match these elements, use the figures as separate context rather than calculating a supposed premium.

Coffee economics extend beyond green-bean price

A roaster must consider sampling, sorting, roast loss, freight, storage, labor, packaging, working capital and expected customer demand. A high nominal purchase price may work for a limited tasting release; a cheaper bag may become costly if quality variation increases waste or customers reject the profile.

Fine Robusta is not defined by being a cheaper Arabica substitute or an automatic premium over every commodity lot. The economic question is whether this particular coffee produces a repeatable result in a specified application.

What belongs in a comparable supplier quotation?

Identify the coffee's country, growing region, producer or processor where documented, harvest, lot code, species, process and offered quantity. Include a dated physical specification and representative sensory evaluation when available. State packaging, currency, price validity, warehouse or origin, delivery basis, freight responsibility, sample status and payment terms.

This information allows a buyer to compare two genuine offers. It also helps a supplier avoid disputes when the approved sample and shipping lot differ. An unknown should be marked 'not confirmed', never filled with an attractive estimate.

What the auction cannot prove for Mondulkiri

The Vietnamese auction bag is already in the United States. Its opening price says nothing about current Origin Coffee Cambodia (OCC.) inventory, Cambodian export logistics, a Mondulkiri cupping score or US demand for Origin Coffee Cambodia (OCC.) Cambodia's own product requires local documents and a sample tied to the offered lot.

Ask three separate questions: Does the coffee satisfy the intended sensory and physical requirements? Can the supplier deliver the described product under agreed conditions? Does landed cost suit the product and buyer? A market benchmark informs context without answering these questions.

Price transparency is an editorial responsibility

Readers searching for a current Fine Robusta price expect a dated, verifiable answer. A stale futures figure misrepresented as a live offer damages trust. Market-intelligence pages should identify the historical reference, explain its limitations and route procurement visitors toward lot-specific documentation or a formal enquiry.

For Origin Coffee Cambodia (OCC.), this article is not a live price feed, inventory declaration or export quote. A useful educational page can remain trustworthy after its news cycle if the date is visible and the claims are kept within their documented scope.

A buyer worksheet

Write down the benchmark's source, trading date and contract. Alongside it, record the proposed coffee's seller, harvest, lot ID, representative sample, quality method and quantity. Add the commercial offer's delivery point, shipping responsibility, price validity and currency. Ask for missing fields before calculating delivered costs.

For a small supplier, a technical sheet, reliable sample and clear statement of what is available are more persuasive than quoting an unrelated auction price. For a buyer, a documented gap is a reason to request information rather than reject an origin outright.

Frequently asked questions

Is 3,391 an Origin Coffee Cambodia (OCC.) wholesale quote? No. It is an external figure reported in a dated market commentary.

Did the Vietnamese auction lot sell for US$5.75 per pound? No completed sale was verified on September 19; this is the opening bid.

Does a futures number establish a Fine Robusta premium? Not alone. The lot, application, quality and delivered terms must be evaluated.

What should a buyer request first? Lot identity, a representative sample, specifications and dated commercial conditions.

Origin Coffee Cambodia (OCC.) takeaway

The goal is to let a buyer move from market curiosity into an evidence-based offer without confusing one price mechanism with another. Read the Fine Robusta pricing framework and see Wholesale Coffee Supply for the commercial pathway.
