Every legitimate cashew shipment arrives with a Certificate of Analysis. Most buyers file it. Fewer read it closely. And a meaningful number are not entirely sure what several of the numbers on it actually mean in practice.

That is a problem, because the CoA is the single most useful document a buyer receives — it is the objective record of what was actually measured on the specific batch in the container, and it is the basis for any quality discussion if something is disputed later.

This guide explains every parameter on a standard cashew CoA, what a normal value looks like, and what a value outside that range actually signals.

What Every Number On A Cashew CoA Means

ParameterNormal rangeWhat it tells you
Moisture3.5–5.0%The single most important shelf-life indicator. Above 5% raises mould risk in transit; below 3% suggests over-drying and higher breakage
Broken / defective %Per AFI grade specConsistently at the top of the allowed range indicates marginal quality control, even if technically within specification
Foreign matterNil / not detectedAnything other than "nil" warrants a direct conversation with the supplier before acceptance
Aflatoxin (total)≤10ppb for EUCheck whether testing was in-house screening or accredited external laboratory — EU-bound product should have external confirmation
Aflatoxin B1≤2ppb for EUTested separately from total aflatoxin. Both limits must be met for EU market access
Colour gradeW (white) or SW (scorched)W is standard for premium retail. SW is acceptable for many ingredient applications at lower cost
MicrobiologicalWithin stated limitsTotal plate count, yeast and mould, and pathogen screening (Salmonella, Listeria) — absence should be explicitly stated

Four Things Experienced Buyers Check Beyond The Numbers

🏭
Who Performed The Testing
In-house laboratory or accredited external lab? Both are legitimate, but EU-bound aflatoxin results should carry external accredited confirmation. The CoA should state which
📆
Batch And Date Traceability
The CoA should reference a specific production batch code and date, traceable back to a specific production run. A CoA without batch identification cannot be traced if a problem emerges
📈
Consistency Across Shipments
One CoA tells you about one batch. Six CoAs across six months tell you whether the supplier's process is genuinely controlled. Always request historical CoAs when evaluating a new supplier
📝
Standard Referenced
Most international cashew trade references AFI (Association of Food Industries) standards. A CoA that does not reference a recognised standard is difficult to enforce in a dispute

The most useful habit a buyer can build: request CoAs from the last three to six production runs before placing a first order, not just after. Consistency across batches is far more informative than a single perfect result.

What Should Prompt A Conversation

Moisture varying widely between batches:  A supplier whose moisture readings swing between 3.2% and 5.4% across shipments does not have tight drying control — regardless of whether individual results are technically in spec
Identical values across multiple CoAs:  Real measurement produces small natural variation. Identical figures across several batches suggests the values are being transcribed rather than measured
Missing aflatoxin results for EU shipments:  Not optional. EU-bound product must have documented aflatoxin testing within regulatory limits
No batch code or issue date:  A CoA that cannot be tied to a specific production run and date has limited value if a dispute arises later
Supplier reluctance to share historical CoAs:  A supplier with controlled processes has nothing to hide in past results. Reluctance is itself informative
💬 CEO Perspective
The CoA is the document that turns a quality claim into a quality fact. We issue one for every batch, referencing the actual measurements from our own laboratory on that specific production run โ€” and we are equally happy to share the previous six. A supplier who will only show you the current one is telling you something.
