Most bulk cashew orders go wrong for reasons that have nothing to do with taste. A batch arrives with more moisture than expected and starts losing shelf life within weeks. A "whole" grade turns out to have more broken pieces than a buyer budgeted for. Or a supplier quietly blends in older stock to fill an order, and nobody notices until a customer complains. None of this is exotic — it's the handful of things that separate a reliable supplier from a risky one, and almost none of it gets asked about upfront.

Check the moisture percentage

Moisture content is the single biggest factor in how long a batch of cashews actually lasts once it leaves the supplier. Industry specifications for cashew kernels generally call for moisture in the 3–5% range (per the Agricultural and Food Industries cashew kernel specifications) — go much above that and shelf life drops fast, especially once the product sits in a warehouse rather than moving straight to a shelf. Ask for the moisture reading on the specific batch you're buying, not a general claim about "our cashews." A supplier who can hand you a number without hesitation is a supplier who's actually testing.

Check the broken-to-whole ratio

If you're ordering a "whole" grade, some broken pieces are normal — cashews are fragile, and a small amount of breakage happens during processing and transit regardless of how careful a facility is. The commonly accepted tolerance is around 10% broken within a whole-kernel grade (again, per AFI's cashew kernel specifications). What matters is knowing that number before the shipment arrives, not discovering it after you've already paid. Ask the supplier what ratio they guarantee, and ask what happens if a batch comes in outside that range.

Ask which harvest batch you're actually buying

Traceability matters more than most buyers realize. Some suppliers blend older stock into a shipment marketed as "fresh" without flagging it — not necessarily out of dishonesty, but because batches get mixed in storage and nobody tracks it closely. Ask which harvest the batch is from, and don't treat vague answers as good enough. A supplier who grades and packs at their own facility, rather than buying loose stock from traders, generally has a much easier time answering this — because they controlled the batch from intake onward.

Know what's actually negotiable

It's worth being clear-eyed about where a supplier relationship has room to move and where it doesn't. Verifying the kernel count against the stated grade is normal due diligence — any serious buyer does it — but the count itself isn't something that moves with negotiation; a W320 is a W320. What is negotiable is price and the finish, meaning the visual quality and consistency of the kernels within that grade. Understanding this upfront saves both sides a confusing conversation later.

How to structure your first order

Even after a supplier checks out on paper, it rarely makes sense to commit a full season's volume to someone you haven't bought from before. A structure that works well for new or first-time buyers is ordering in part-shipment tranches — say 1–2 tonnes at a time, each priced at that week's market rate. It lets you test consistency across two or three shipments — moisture, breakage, batch quality — before scaling up, without either side carrying the risk of one large order locked at a single price.

None of this is complicated, and none of it requires special access or leverage — it's just a short list of questions most buyers never think to ask until something's already gone wrong. Ask them upfront, and a supplier relationship starts on the right footing instead of a guessing game.
