How to Qualify a Whole Cultivated Ophiocordyceps sinensis Sample Before a B2B Order

Short answer: approve a B2B sample only after the supplier and buyer agree in writing on the product identity, grade criteria, sample source, evaluation method and acceptable variation. A photograph or grade name alone is not enough.

1. Confirm what the sample actually is

Use the accepted scientific name Ophiocordyceps sinensis and record any synonym used in commercial or regulatory documents. State clearly that the material is cultivated and supplied as whole-form raw material. Do not treat Cordyceps militaris, an extract, powder, mycelial biomass or another fungal material as interchangeable.

The buyer should also define the intended downstream use and destination market. Product classification and permission can change with the species, part, processing method, intended use and country. For example, the European Commission describes its Novel Food Status Catalogue as a non-binding reference tool, so the responsible operator still needs to verify the proposed use with the relevant authority.

2. Turn the four grades into measurable purchasing language

Jian'an's four commercial grades—Premium, Grade I, Grade II and Broken Pieces—are useful for quotation and sorting, but the final contract should define the measurable criteria behind the selected grade.

Compare the Jian'an four-grade framework.

3. Ask how the sample relates to the future lot

• Is it taken from an existing identified lot, a retained sample or a development sample?
• What lot or sample code appears on the label?
• When was it packed, and under what stated storage conditions?
• Will the bulk order be released against the same written specification?
• How will unavoidable natural variation in whole materials be handled?

WHO quality-control guidance for herbal materials treats sampling as a foundational step and includes methods for examining foreign matter, moisture-related measures and contaminants. The exact methods and limits must nevertheless be agreed for the product and market concerned.

4. Use a simple sample-approval record

1. Request: send intended use, destination, required grade, quantity range and desired packaging.
2. Specification: review the supplier's proposed specification and mark any buyer-specific requirements.
3. Sample: record sample code, receipt date, package condition and photographs.
4. Evaluation: compare identity, grade, appearance, size convention, foreign matter and any agreed laboratory parameters.
5. Decision: approve, reject or approve with written conditions.
6. Purchase order: reference the approved specification and sample record—not only a photo or informal message.

Questions to include in your first inquiry

• Which grade best matches my required presentation and processing use?
• Can you provide a written specification before sampling?
• Which documents can accompany the sample and the commercial lot?
• Can packaging be reviewed during the sample stage?
• What information do you need to assess destination-market requirements?

Prepare a sample request

Send your target market, intended application, preferred grade, estimated order range, required documents and packaging format. Jian'an can then discuss whether an appropriate sample can be prepared; availability and test scope must be confirmed for each request.
