Examples of origin-claim evidence
Use the same standard for PEL and any competing supplier.
| Observed statement or record | What it may establish | What remains separate |
|---|---|---|
| A U.S. laboratory report | The report’s named laboratory and sample tests. | Production origin and current-lot linkage. |
| A domestic dispatch record | The documented fulfillment event. | Manufacture, identity and analytical results. |
| A company address | A stated business contact location. | Which entity produced or tested the material. |
| A supplier origin statement | What the supplier claims. | The original evidence supporting the exact claim. |
PEL sources
PEL provides original report links and current shipping terms. Those sources should be read for the questions they actually address, without turning testing or dispatch into a broader manufacturing conclusion.
Other suppliers
Request the same original, lot-relevant evidence. This page does not attribute an unsupported origin claim to Ascend BioLabs or declare an unknown supply chain fraudulent.
