Cambodia Robusta Pre-Shipment Sample vs Contract Sample: What Should Match

Green coffee buyers often approve one sample and receive another representation of the lot before shipment. The terms can become confusing unless the buyer defines what each sample represents. For Cambodia Robusta, the most important rule is simple: the commercial shipment should remain traceably connected to the coffee and specification that the buyer approved.

Understand the sample roles

An offer sample helps the buyer decide whether a lot is interesting. A contract sample may document the quality agreed at purchase. A pre-shipment sample is used to check the prepared shipment before it leaves origin. Suppliers may use different terminology, so the purchase agreement should state exactly what each sample means.

What should remain consistent

The sample and shipment should align on lot identity, crop year, origin, processing method, agreed grade or physical specification, packaging, and the sensory attributes defined in the contract. Natural agricultural variation exists, but the buyer should not discover an unexplained change in quality only after arrival.

Use measurable acceptance criteria

Instead of writing “same as sample,” define the attributes that matter: moisture range, defect tolerance, odor, cleanliness, key sensory characteristics, and any required screen or preparation standard. The contract should also describe what happens when the pre-shipment sample falls outside the agreed range.

Keep the evaluation protocol stable

Compare samples using the same sample roast, rest period, cupping or brewing method, and evaluation team when possible. A different roast can make the same green coffee appear substantially different.

Document approvals

Record sample ID, date received, lot code, evaluator, decision, and any conditions attached to approval. If the buyer approves a pre-shipment sample with a minor exception, put that exception in writing rather than relying on chat history.

The purpose of pre-shipment control is not to eliminate every difference. It is to detect meaningful differences before the coffee moves across borders. A clear sampling protocol gives both buyer and supplier a fair reference when quality questions arise.
