Jian'an CordycepsBuyers should request written storage conditions and evidence supporting the proposed shelf life for the exact material and packaging being purchased. Do not assign a standard expiry period to whole cultivated Ophiocordyceps sinensis simply because another supplier uses one. Unopened storage, transport and handling after opening need separate decisions.
What evidence should support a shelf-life statement?
Ask what product, package and storage conditions were assessed, which quality attributes were followed, and who approved the conclusion. A release test report describes the tested sample at the time of testing; by itself, it does not establish future shelf life.
The following is a proposed purchasing checklist, not a statement that Jian'an Cordyceps has completed a particular stability study.
| Question | Evidence or written agreement to request |
|---|---|
| What is the claimed unopened shelf life? | Its starting date, supporting assessment and applicable pack configuration. |
| Which storage conditions apply? | Product-specific instructions and the basis for any numerical limits. |
| Does the claim cover repacking? | A separate assessment for the proposed new pack; do not assume equivalence. |
| What happens after opening? | Handling instructions and a justified use period, where established. |
| Who reviews transport deviations? | A named decision owner, records required and disposition procedure. |
How should a buyer prepare the warehouse?
Before delivery, compare the agreed instructions with the actual receiving and storage arrangements. Assign a lot location, preserve labels, record opening dates and prevent accidental mixing. Decide whether monitoring is needed and how records will be reviewed. These are suggested controls to discuss with the buyer's quality team, not universal numerical requirements.
What if a shipment experiences an unexpected condition?
- Separate the affected stock from material approved for use.
- Record the package condition, timing and available transport observations.
- Send the evidence to the responsible quality contact.
- Obtain a documented assessment before release, repacking or disposal.
Do not extend an expiry date solely because the material still looks acceptable. If no supported shelf-life conclusion is available, resolve that gap before committing to a long holding period.
Does visual grade change the storage requirement?
Jian'an Cordyceps uses Premium Grade, Grade I, Grade II and Broken Pieces primarily as visual categories. These names do not establish different shelf lives, moisture limits or storage temperatures. The product is artificially cultivated Ophiocordyceps sinensis material, not wild-harvested cordyceps or Cordyceps militaris.
Scope and reference
WHO's storage and distribution guidance addresses medical products. It is a reference for supply-chain risk management, not a product-specific storage specification or evidence that this raw material is a medical product, approved for a destination, or certified by WHO.
