An assay certificate is the document that tells you what the gold is worth. It is also the document most likely to be controlled by the party selling to you. Seller-provided assay results can be accurate, but they can also be staged, recycled from a previous batch, or taken from a different material entirely. This guide explains what independent inspection and assay oversight gold buyers should require before payment — and how to structure it so the results you rely on are not produced by the seller.
Why seller-provided assay is a structural risk
The issue is not that sellers are dishonest. The issue is structural: when the party providing the quality measurement is the same party whose price depends on that measurement, the buyer has no independent control. Even honest sellers occasionally present optimistic results; dishonest sellers present results that bear no relationship to the actual material.
The control is simple in principle: require that the assay a buyer relies on for payment be produced by an independent, reputable party — not selected or controlled by the seller.
What "independent" actually means
Independence has three components. The assayer must be independent of the seller (not a related party, not selected solely by the seller). The sampling must be independent (the sample tested must actually represent the material being shipped, not a separate, higher-grade piece). And the reporting must be independent (results sent directly to the buyer, not filtered through the seller).
A seller who proposes their "usual assayer" and offers to "pass on the results" is not offering independent assay. They are offering seller-controlled assay with a third-party name on the certificate.
Pre-shipment inspection for bullion, dore, and raw forms
The inspection approach varies with the form of gold being traded. For bullion bars, inspection includes verification of bar marks, weights, and serial numbers against accompanying documentation, and visual confirmation of condition. For dore, the focus is on sampling and assay, because the value depends on composition that cannot be confirmed visually. For raw or dust gold, sampling methodology is critical — a single grab sample can be unrepresentative or staged.
Veritas does not operate a laboratory and does not issue assay certificates. Where instructed, we coordinate and oversee independent pre-shipment inspection so that sampling is performed properly, by reputable parties, and the results are reported directly to the buyer.
What buyers should require before payment
The exact requirements depend on the transaction, but the following are the controls we recommend to gold buyers as a baseline.
Minimum inspection controls before payment:
- Independent sampling performed by a party not selected solely by the seller
- Sample taken from the actual material proposed for shipment, not a separate reference sample
- Assay performed by an accredited, reputable laboratory with results sent directly to the buyer
- Weights and, where applicable, bar serial numbers verified against the documentation
- Condition and form of the material confirmed to match what was described in the offer
- For dore and raw forms, sampling methodology documented and appropriate to the material
When remote oversight is and is not enough
For some transactions, a buyer can specify the assayer and require results directly — and that may be sufficient if the seller is established and the material form is straightforward. For higher-risk transactions, new suppliers, or material forms where sampling is difficult (raw and dust gold), on-ground oversight of the sampling itself is the only credible control. A certificate is only as reliable as the sample it was drawn from.
Cost vs. capital at risk
Independent inspection has a cost, and buyers sometimes hesitate to incur it for smaller transactions. The framing should be different: the cost of independent inspection is a fraction of one percent of the transaction value, while the capital at risk is the entire payment. For any transaction where the loss would matter to you, independent inspection before payment is the rational control.

The assay a buyer relies on should be produced by an independent party, from a representative sample of the actual material, with results sent directly to the buyer. Anything less is seller-controlled quality.
Frequently Asked Questions
Does Veritas perform the assay itself?
No. We do not operate a laboratory and we do not issue assay certificates. Where instructed, we coordinate and oversee independent inspection so that sampling and testing are performed by reputable, independent parties and results are reported directly to the buyer. We provide oversight, not lab services.
Can I use the seller's assay if it comes from a named refinery?
A named refinery adds credibility, but it does not guarantee the certificate applies to the material you are being offered. Certificates can be recycled. Verify that the certificate details — weights, dates, bar numbers — match the actual material, and where the value justifies it, require independent re-sampling.
What is XRF and is it enough?
XRF (X-ray fluorescence) is a non-destructive technique used for rapid surface composition analysis. It is useful as a screening tool but has limitations, particularly for heterogeneous material and for detecting certain elements. It is not a substitute for a full fire assay where precise fineness determination is required for valuation. We can coordinate XRF screening as part of oversight, but we do not present it as equivalent to a certified assay.
