Is it worth requesting a certificate of analysis for a bulk lot of mixed precious-metal electronic scrap?
Short answer: For a genuinely large or valuable bulk lot, requesting a certificate of analysis, either from the buyer's own testing or an independent lab, is a reasonable and often worthwhile step — it gives you documented, specific figures for the precious metal content rather than relying on a general estimate, which becomes more valuable the larger and more valuable your lot actually is.

A proper certificate of analysis gives you specific, documented measured figures for the precious metal content in your lot, rather than a general estimate — this is meaningfully more precise and useful for a genuinely valuable, mixed lot where the content isn’t obvious just from visual inspection.
Why this matters more for larger, mixed lots specifically
A small, simple lot of similar items might not justify the cost and effort of formal analysis, but a large, genuinely mixed lot of electronic scrap with varying precious metal content across different component types benefits significantly from documented, specific figures rather than a rough overall estimate.
Whether to use the buyer’s analysis or an independent one
A buyer’s own certificate is a reasonable starting point, but for a lot valuable enough to justify the extra cost, an independent lab analysis provides a genuinely neutral figure you can compare against the buyer’s own assessment.
